What is Diamonds?


Diamond is a native crystalline carbon that is the hardest known mineral. It is usually nearly colorless. When transparent and free from flaws it is highly valued as a precious stone. It is also used industrially, especially as an abrasive. Crystallized carbon produced artificially is also called diamond.


The name diamond is derived from the ancient Greek adamas ("invincible"). Their hardness and high dispersion of light make diamonds useful for industrial applications and jewelry. Diamonds make excellent abrasives, because they can be scratched only by other diamonds, or man- made materials, which also means that they hold a polish extremely well and retain their luster.


They have been treasured as gemstones since their use as religious icons in ancient India. Their usage in engraving tools also dates to early human history. The popularity of diamonds has risen since the 19th century because of increased supply, improved cutting and polishing techniques, growth in the world economy, and innovative and successful marketing campaigns.


Gem diamonds are commonly judged by the “four Cs”: carat weight, clarity, color, and Cut.


Historically, diamonds were found only in alluvial deposits in Guntur and Krishna district of the Krishna River delta in Southern India. India led the world in diamond production from the time of their discovery in approximately the 9th century BC to the mid-18th century AD, but the commercial potential of these sources had been exhausted by the late 18th century and at that time India was eclipsed by Brazil where the first non-Indian diamonds were found in 1725. Currently, one of the most prominent Indian mines is located at Panna.


Several methods for identifying synthetic diamonds can be performed, depending on the method of production and the color of the diamond. D-J colored diamonds can be screened through the GIA. Stones in the D-Z color range can be examined through the Diamond Sure UV/visible spectrometer, a tool developed by De Beers. Similarly, natural diamonds usually have minor imperfections and flaws, such as inclusions of foreign material that are not seen in synthetic diamonds.
