What Are Synthetic Diamonds?

Synthetic diamonds are grown in a laboratory and have essentially the same chemical composition and crystal structure as natural diamonds formed millions of years ago. In the last 30 years, gem quality synthetic diamonds have been grown in Japan, South Africa, Russia, Ukraine and the United States. Synthetic diamonds are generally produced using either High Pressure/High Temperature (HPHT) or Chemical Vapor Deposition (CVD).


Cut: The 4th C

When you oooh and ahh over a sparkly diamond, to a large extent you’re reacting to its cut. What you want is light to enter through the crown table (the flat part at the top) and go to the pavilion (the pointy part at the bottom), where it reflects from one side to the other, and then back out of the diamond through the crown table. This ensures maximum sparkle and brilliance. Think spectacular laser show!
