Cultured Diamonds

Cultured diamonds, often produced by chemical vapor deposition, is a method of growing diamond by creating the environment and circumstances necessary for carbon atoms in a gas to settle on a diamond substrate in diamond crystalline form. This method of diamond growth has been the subject of a great deal of research since the early 1980s, especially due to its potential applications in the cutting tool, semiconductor and diamond gem industries.

In their pioneering work in the area, the Japanese passed a mixture of carbon-containing gas (methane in their case) and hydrogen into a quartz tube at a pressure of 0.05 atmospheres. Using microwaves the mixture was heated to 800 °C, disassociating both the methane and hydrogen into elemental forms. The carbon is deposited on a substrate, the majority as graphite but a very small proportion as diamond crystal. the graphite is 'removed' by the hydrogen leaving a thin layer of diamond, initially the layer was around 25μm in thickness.

Our cultured diamonds are of the highest quality, most often exceeding the quality of the finest natural diamonds. While cultured diamonds have traditionally experienced a slow period of growth, that growth has recently spiked. With growing recognition of the quality of cultured diamonds in realtion to natural, there is also growing acceptance.

Also, cultured diamonds of such high quality represent a technological milestone of incredible proportions, allowing for future advancements in the fields of computer processing power, laser technology, and data storage. Cultured diamonds are going to change the face of technology, not to mention allowing that special someone to wear an exquisite gem...without a second mortgage.
