There are two techniques for growing synthetic diamonds One is HPHT (High Pressure High Temperature), and the other is CVD (Chemical Vapor Deposition),
The HPHT diamond manufacturing system employs the use of dissolved catalysts tor encouraging the growth of the diamond.
The catalysts used leave evidence ot their use in the stone, in a minute quantity, which doesn't occur in a natural diamond.
Diamond Services ensures the integrity of the diamond jewelry sold by jewelry retailers before they're placed in their stores. Lab grown diamonds have become more prevalent in finished jewelry. Because these stones are difficult to detect, the need for accurate testing to determine whether or not a piece of jewelry contains all natural diamonds is more important than ever; especially for the end consumer. Diamond Services is different. We are the only company within the industry that uses a state-of-the-art unique process that detects the presence of lab-grown diamonds in both finished jewelry and loose diamonds; making us the leading choice for identifying them.
