Diamond Information

Certification: GIA

Cut: Fair
This diamond reflects light well and represents a much lower price than a diamond with a Good cut grade.
Color: E
This diamond is considered colorless but may have a slightly different degree of transparency than a D color, which is only noticeable to an expert grader under laboratory conditions. Diamonds with a color grade of E are very rare. They appear a brilliant white in the setting and will cost slightly less than a D color, depending on other quality factors.
Clarity: IF
This diamond has a clarity grade of IF, or internally flawless, which means that the diamond shows no internal inclusions under 10 power magnification, but it might have very tiny blemishes or transparent polish marks on the surface of the diamond. Diamonds with an IF clarity grade are extremely rare, and the value will reflect this.

Diamonds – The Hardest of All Minerals
Posted (Super Gem Jewelry) in Diamonds on September-17-2008

Diamonds are minerals. They are know as the hardest known mineral. Diamonds are also possible to treat under high pressure and temperature to produce diamonds that are much harder to used in hardness gauges. Diamonds make excellent abrasives as they can be only scratched only by ultrahard fullerite, borazon of diamonds.With these properties diamond hold a polish extremely well and retain their lustre.

Diamond derives from the ancient Greek and diamonds have been treasured as gemstones as religious icons in ancient India and using diamonds as engraving tools in early human history.

What do a glittering diamond and a lead pencil have in common? Diamonds are very hard and the graphite of the pencil’s tip is very soft. These two different substances contain a wonderful proof of creation called carbon.

A rough, unpolished diamond is the hardest of all minerals. For this reason, a crystal diamond is used to cut and to drill all kinds of material and is also used as an abrasive to smooth surfaces.
Hardness is the resistance of a mineral to scratches from outside forces; it is easy to recognize minerals by this trait. By scratching one mineral with another, their relative hardness can be determined. Scientists use a point system to designate the hardness of all minerals. They rate diamonds with the highest ratio of ten over ten. So, what makes diamonds so hard?

It is very interesting that the soft, breakable graphite in a pencil tip is made up of the same atoms as a diamond. Graphite is composed of the same carbon atoms as a diamond. But, while one is very soft, the other is extremely hard. One is as black as a lump of charcoal; the other may be sparkling bright. One is commonly found in nature; the other is rare. For all these reasons, diamonds are much more valuable than graphite. How is it then, that carbon atoms can be so different from one another?In 2000 De Beers became known as the Diamond Trading Company (DTC), which is now the Supplier of Choice in the global distribution channel.
