A diamond blade is an industrial tool used in the construction field for cutting hard or abrasive materials like stone, concrete, brick and also for shape cutting different objects and rigid materials. Diamond blades are available on the market in a large variety of sizes, shapes and types as well as a lot of different uses. A diamond blade works by a very simple and yet pretty interesting principle: diamond crystals form the blade saw of the cutter which is held in a metal stand; while cutting into hard materials the diamond blade wears down and at the same time, new diamond crystals are being exposed for use.

An important aspect of the diamond blades is the fact that they do not actually cut into the materials but grind by means of thousands of rectangular teeth forming the blade saw. There are more working variants of the diamond blade: some are designed to cut on dry surfaces especially when they are used on electrical saws but this particular type of diamond blade is endangering for the health due to the dust released and presents high risk when used by inexperienced workers. Most commonly encountered diamond blades are those used in presence of a water jet meant to cool off the surface, the blade and eliminate the dust released during usage.

In the construction industry where diamonds are mostly used, as well as in other fields where diamond blade saws can find utilization, diamond blades are usually grouped into six major categories containing general purpose blades, grinding cups, laser welded, tuck pointers, core bits and other diamond blades.

The general diamond blade group of cutting saws can be used for cutting concrete, brick , block or granite, can be utilized wet or dry and have a good life duration. Grinder cups diamond blades are suitable for fast grinding in stone or concrete and are composed of two rows of diamond crystal segments to leave a highly smooth surface. Tuck pointers are a necessity when it comes to finishing construction works; it is the best choice for routing and cleaning mortar joints. Laser diamond blades are used for a multitude of purposes when it comes to cutting semi-abrasive materials.

Usually, an industrial diamond blade is assembled on an automatic machine with singular or multiple cut-off blades. Before being released on the market for sale, diamond blades must undergo a series of very meticulous verification procedures; when the verification is completed, a guarantee certificate will be attached to the products specifying the cutting operations it can be utilized for and the effectiveness for every material in particular.

Diamond blades are at high request in the hard industry field. Quality products are always most wanted in spite of the higher prices as they guarantee a quality work and a longer period of time before requiring to be changed. A large number of specialty web sites offer for sale diamond blade products for any purpose you may think of. Clients can buy online and save time or place their order by calling the given phone numbers.

Good King Wenceslas was a diamond of a human being indeed, in the short time he enjoyed the throne of Bohemia. He shared his new Christian joy with his people, and his desire to have Bohemia join with the new Holy Roman Empire of Charlemagne and become a part of a renewed, larger border free Europe. This in 912.

However, his mother who was still a pagan was not amused. She saw the pagan ways special to Bohemia for many centuries as having to give in to a larger central government far away near Brussels today- do you hear that irony in the historic wind?- led by the great new convert to Christian beliefs and education, Charlemagne.

Gone would be the local ways and customs and giving in to a central authority was not for our ways. So Wenceslas banished his mother from the kingdom, her allies brought forward his pagan brother Boleslav, by most accounts a violent fool, who began to make impossible demands of new King Wenceslas. He wanted a stone castle on low ground at the confluence of two rivers: even the King lived in a wooden castle in 912.

Soon, most cowardly by Boleslav and his men in front of a church door, Wenceslas was cut dead. The pagans had won, and Bohemia stayed ignorant and outside the civilization that Christian monks brought to all around.

So much so that the beloved grandmother of young Prince Wenceslas, St. Ludmila, who had been strangled by Wenceslas’ own pagan mother, and Wenceslas himself were adored and enshrined in the hearts and souls of the good people of Bohemia. Within a century converts of good King Wenceslas dared to come forth.

Soon the pagans lost control of the ceremonies, and most of all the hearts of the people. Saint Ludmila and her grand son Good King Wenceslas were very good indeed, and when they looked down on the feast of Stephen, every where he looked around the frost was deep and even.

And as empires lift and fade after great men die too soon, the mists of time blended over this first greater out of the dark ages attempts to bring about a border less market free Europe. It has been a way from 912 to today, and there have been some terrible bumps and off ramp crashes, but here we are.

Well done, great visionaries. Burn in Hell, Boleslav. God and St. Peter willing, I hope to see you inside Heaven at Christmas, Wenceslas: can they arrange frost that crunches deep and crisp and even? We will see. But the question what if reamins in front of us so open to vision.

What if Wenceslav had not turned his back on the treacherous brother and his thugs, and believe his hand on the church door would stop them from killing him?

What if Charlemagne had been aware of the treachery in the court of his dear new friend Wenceslas and sent soldiers of Christ to prevent these pagans from allowing Europe to spread east as it has only managed now.

That was 912, and today in 2008 we can say it is a good thing, long overdue, could have saved hundred of millions of lives in wars, but seems to be happening now.A diamond of an idea, so long overdue.

So, you’re new to the real estate market and you’re having lofty dreams of making a mighty mint flipping houses, well, take heed of this solid advice that’ll help you choose a “good” fixer-upper. Flipping houses can be risky business, but it need not be so. The goal here, is to find a true diamond in the rough- a diamond that needs just a bit of buffing up in order to shine. Especially if you’re just starting out in the flipping market, you don’t want to be dumping tens of thousands of dollars that you just might not re-coup at the end of the day. Ideally, you want something that with the magic of paint, a sharp stylistic eye and some good old elbow grease can turn into a gem- a gem that’ll pay you back your invested time and money, and then some.

The classic rule for a good real estate investment is to purchase the worst house in a great neighborhood. This rule holds even greater weight when it comes to flipping. Oftentimes these are the houses you can scoop up for a deal, and then your job is relatively easy. If the house is structurally sound, you just need to bring it up to snuff with the surrounding neighborhood. This is ideally a cosmetic job- one that’ll require minimal funds and maximum sweat. You want to mine out a job you can do without hiring any outside contractors. The sweat input will be all your own and so you won’t be dumping huge dollars anywhere. The only time you’ll see the huge dollars is when you turn around and flip the property.

Now, it may be a challenge to find a great bargain in a hot neighborhood. In this case you’ll have to expand your hunt. Again, you still want to follow the advice of the friendly chime, “location,location,location”. You may end up having to scout out potential “up and coming” neighborhoods that are bordering already established and affluent neighborhoods. Look for early signs that point towards a neighborhood’s gentrification, such as other renovators working on homes. Look for perks in a particular neighborhood that make it stand out, such as proximity to parks, trails or beautiful views of water or mountains. Likewise, central location that is close to a downtown and/or other important amenities speaks volume about a neighborhood’s inherent worth.

Another aspect to look for in a good “flippable” neighborhood is the quality of schools. It is said that quality of education tends to be a number one selling point for buyers. So make sure you do your homework and know the proximity and quality of educational institutions in the neighborhood you’re scouting in.

When searching for that perfect bargain remember, dirt, grime, clutter and bad curb appeal are actually your friends! So many other buyers may judge a home’s worth based on first impressions, and the aforementioned elements are definite turn offs. All the better for you, because if the house is structurally sound and just needs minor repairs, some thoughtful landscaping and some paint, well then you’re looking at a good investment. These houses tend to stay on the market for longer, in which case you may be able to low ball on your offer, optimizing your profit margins even more.

Be systematic when scouting our the homes. Know that all that clutter might be hiding the true layout of the space. Pack a tape measure and digital camera to remind of the true dimensions of a space.

You really want to be judicious about your limitations. One extra big project could slash your potential profit margin. Stay away from homes that needs major upgrades in order to be marketable, such as roof replacement, leaky basements, cracked foundations and severely uneven floors. Having to completely upgrade a kitchen can set you back $20,000, and if you’re looking at a bathroom, keep in mind the investment could be in the ball park of $10,000. Again, think of cosmetic upgrades that will lift the property to new market heights, and won’t drag you down financially.

As you’re hunting you’ll also want to be cautious of homes with existing renovations as you have no assurance if they were done properly. They’ll also tend to jack up your cost of purchase.

When looking at homes, keep an eye out for hidden treasures, such as hardwood floors tucked under green shag carpet. Yes, sometimes, you just might find $15,000 under an ugly carpet- or at least that much worth in wood flooring.

As mentioned earlier, no curb appeal is a great thing for the house flipper. Some thoughtful landscaping elements can add huge value in curb appeal to your home, and is certainly a project you can “dig” into yourself.

So just remember, young flipper, a real bargain is one that needs only cosmetic touch ups, and not a complete face lift!

Those who are thinking about buying diamonds either as an investment, for mounting in custom diamond jewelry, or simply as an addition to a collection, it is a good idea to educate yourself on the subject. Not all diamonds for sale are necessarily a good value; the old Roman advice caveat emptor is especially applicable when it comes to buying diamonds.

Getting Started

There are two things you need before you start buying diamonds:

1. A thorough knowledge of the diamond market

2. Where to obtain reliable appraisal services

The latter is especially important. Any appraisal of certified diamonds should be undertaken by an independent agency that has no connections to or interest in the wholesaler or retailer who is offering the diamonds for sale in which you are interested.

This may require a bit of detective work. The problem is that the world diamond market is controlled by a relative handful of corporate and international banking interests. However, it is well worth your while to find such appraisal services so as to insure that your interests are protected when buying diamonds.

The “Four Cs”

The laboratories that analyze diamonds for sale examine these gems for four different objective characteristics:

* Carat: this is the weight and mass of the gem, equal to .2 grams.

* Cut: the way the stonecutters have shaped the gem, i.e. “round” or “square” and how well this has been done

* Clarity: this looks at any internal flaws, such as a “cottony” appearance within the gem

* Color: certified diamonds can range in color from crystal clear to dark amber and even black.

This analysis is done prior to the actual appraisal, but is an important part of the process.

The Appraisal

While a lab report is based on objective, observable criteria, an appraisal is more subjective. The purpose is to determine the market value of these gems, primarily for the purpose of insuring them.

So – how much will you pay when buying diamonds? This is what the appraisal will determine.

Some cuts are more valuable than others. Princess cut diamonds, which have grown tremendously in popularity over the past thirty years, are the product of a unique cutting method developed in 1979 by a Los Angeles jeweler. These gems combine elements of “round” and “square” cuts; the princess cut diamonds results in the lowest amount of waste, so the diamond retains more of its original mass and weight.

These are only a few of the issues that should be kept in mind when buying diamonds, but they are the most important.

Clarity refers to an objects transparency or purity. This is a very important characteristic for diamonds. To determine a diamond’s clarity the placement, appearance, and number of inclusions, blemishes, or flaws are noted. The number of inclusions, blemishes, or flaws can affect the opacity of the diamond, its sparkle, and its overall brilliance.

The Gemological Institute of America (GIA) is a not for profit institution dedicated to research and education in the field of gemology. The GIA is responsible for creating a gem scale to rate diamonds clarity.

The scale is as follows:

Flawless(FL): This refers to a diamond that does not have any blemishes or inclusions at all when viewed under a 10x magnification by an experienced diamontologist.

Internally Flawless(IF): This refers to a diamond that does not have any inclusions, but may have some minor blemishes when observed by a certified diamontologist under a 10x magnification.

Very Very Slightly Included(VVS1 and VVS2): This refers to a diamond that has very tiny inclusions. These inclusions will be hard, even for an experienced diamontologist, to see when using a 10x magnification.

Very Slightly Included(VS1 and VS2): This refers to a diamond that has very minute inclusions such as small clouds, feathers, or crystals when observed under a 10x magnification.

Slightly Included(SL1 and SL2): This refers to a diamond that has noticeable inclusions such as clouds, feathers, or crystals, that are evident to an experienced diamontologist under a 10x magnification.

Included(I1, I2, and I3): This diamond is often referred to as imperfect. It may contain some inclusions that are fairly apparent to an experienced diamontologist that may be visible without any magnification.

From the above definitions it is easy to tell that you do not want your diamond to have too many inclusions, but what exactly is an inclusion? An inclusion is an internal characteristic that, due to the immense pressure it takes to create a diamond, is often formed during the formation process or caused by an irregularity in the crystal structure. A blemish on the other hand is an external characteristic that can be caused during the formation of the diamond, during the cutting process, or by everyday wear.

There are many different types of inclusions. One common type of inclusion are feathers. Feathers look quite literally like feathers and in some cases extend to the diamonds surface. The diamonds stability can be affected if the feathers extend to the surface of the diamond. Some other types of inclusions are bearding, cleavage, crystals, and pinpoints.

One common type of blemish is naturals. Naturals refer to a part of the diamond that was not polished during the original cutting/polishing phase. Hence they are still natural. Some other examples of blemishes are fracture, nicks, and scratches.

These inclusions and blemishes are not always a bad thing. They are used as a way to identify diamonds. A truly flawless diamond is very hard to find and very expensive as well. It is always a good idea to have your jeweler plot your diamonds characteristics so that you can easily identify it in the future.

Diamonds are made up entirely of carbon. Pressure (diamonds can’t form above 100 miles below the earths crust) and temperature (750+ degrees F) are the factors that “change” the diamond from mere carbon into a treasured commodity. After millions of years undergoing this pressure and heat, the rough stones are settled in diamond-bearing rock and from there, wait for a volcanic eruption to bring them to the surface.
Diamond Mining Techniques

Pipe Mining: Primary Source-refers to the process of diamonds emerging to the earth’s surface in host rocks through volcanic pipes, which are pathways between the earth’s mantle and surface.

When an eruption occurs, other materials are carried up along with the magma, or lava. If the eruption originates far enough down in the earths surface, it could contain diamond-bearing rock, usually kimberlite or lamproite.

These eruptions must be extremely forceful and move at high speeds, for if the diamonds remain in the magna for a long period of time, they could burn up if the temperatures or turn to graphite.

From here, they conduct a process called open mining where the surface remnants are inspected for diamonds. Once those are exhausted, large shafts are plunged into the ground next to the volcanic pipes and more diamond-bearing rock is recovered, and taken to a screening plant where the soil is separated from the diamonds.

Diamond Mining
Alluvial Mining: Secondary Source- Refers to the removal of rough diamonds that have been relocated to oceans and riverbeds through erosion.

After an eruption occurs, some of the diamond bearing rock is displaced, often settling in ocean beaches and river beds. To extract this valuable substance, a process of Alluvial Mining is conducted. In order to remove the rock from these areas, the water must be pushed aside to get to the floor of the ocean or river. Usually a wall of mud and stone is constructed. From there, the miners using bulldozers or pumps bring the rock to the surface. It is then taken to a screening plant where the soil and silt can be separated from the rough diamonds.
Rough Diamond Quality

After the rough diamonds are mined, less than 20% are gem-quality, the other 80% have other uses. If not gem–quality, they fall into one of two other categories Near Gem-Quality or Industrial use diamonds.

Gem Quality: Approximately 20% of diamonds mined fall into this category. These are high enough in quality to be used in diamond jewelry. They range in clarity from Flawless to Visible Inclusions.

Near Gem Quality: These fall in a category between gem quality and industrial, so they need to be individually evaluated to determine if they could be used in jewelry in some way or if the quality is just to poor they are used in industrial ways.
They range in clarity from Visible Inclusions to industrial quality.

Industrial Quality: These diamonds are badly included stones and are functional only for industrial use; for example drills and saws or earthmoving equipment. These are categorized as industrial quality clarity.
