However, instead of mined diamonds, which formed beneath the ground billions of years ago, your diamond was grown in controlled laboratory conditions using sophisticated methods of chemical synthesis. The most modern technology There are two scientific approaches to diamond creation.
The Chemical Vapor Deposition (CVD) process releases carbon from plasma. This involves superheating hydrocarbon gas in a vacuum to between 3,000-4,000C, at which point the carbon atoms begin to separate from their molecular bonds. Those atoms descend and land on a flat wafer of previously grown synthetic diamond and grow in vertical layers.
This substrate is square for jewellery applications but the shape can vary for other applications in medicine, communications and technology. The High Pressure High Temperature (HPHT) process replicates the natural conditions under which diamonds formed 100 miles below the surface due to subduction. A carbon source, a diamond seed and a metallic catalyst go into an octahedral cell.
The cell is placed into a massive mechanical press where the contents are heated near 1,500 C and subjected to staggering pressure. The melting metal dissolves the carbon and the pressure causes precipitation to the diamond seed, growing a larger diamond. The level of pressure from these immense presses has been compared to what you'd experience if you balanced a jumbo jet on the tip of your finger. Four main factors are considered when judging a diamond's quality and value. They are the diamond's 4C's: Carat weight, Color, Clarity and Cut.
IGI screens every diamond using state of the art technologies to determine naturally mined, laboratory grown or simulant origin. Experienced graduate gemologists conduct further assessment in controlled conditions, detailing relevant gemological characteristics according to the strictest international system. Your diamond is exceptional and distinctive. No two diamonds are alike.
Yet all diamonds have certain features in common that allow experts to compare and evaluate them. The name diamond is derived from the ancient Greek "adamas" meaning unbreakable, untamed and unconquerable. Diamonds have been treasured as gemstones ever since they were discovered. In our modern age the word "diamond" continues to evoke images of elegance, style and glamour. Diamond symbolizes purity and strength.
And the story of your diamond is uniquely yours.
