Man-made Diamonds Are Getting Better.

The growing concern over separating man-made or synthetic diamonds from natural ones is well grounded on the fact that this gem species is one of the hardest ever to segregate visually, even for gemologists. In fact, for stones that are grown using the HPHT (High Pressure, High Temperature) method, exposure to the trade and processes involved with manufacturing synthetic diamonds allowed laboratory gemologists to take note of certain characteristics observable in grown stones. These include specific types of metallic looking flux residues, and peculiar looking growth marks that showed the difference in a stone's crystal-development history.



The HPHT method has been the staple of the jewelry industry for many years, and still accounts for the production of many of the world's synthetic diamonds today. Despite this, more and more technologically advanced companies have been working on (and developing proprietary advancements) the other method of diamond growing called Chemical Vapor Deposition or CVD for short. This type of synthetic diamond is much less likely to show visible traces of its synthesis today. The diamonds themselves are grown from flat sheets, by depositing material layer by layer from a carbonaceous cloud of gas (like methane).



Synthetic CVD diamonds have finally reached the point where their colors and clarities produced can be directly comparable to those of high quality natural diamonds. While synthetic diamonds sold on with open disclosure and honest documentation are very beautiful products, the problem lies in the sale of synthetic stones under the guise or label of 'natural diamonds'. These are two different categories of salable gems with two different price points in the trade, and therefore should not be mistaken for one another.

Gemcamp laboratories maintains both gemological instrumentation and advanced spectrometers that can detect both HPHT and CVD synthetic diamonds and separate them from natural counterparts. We combine the use of scientific equipment with the knowledge of our gemological staff, and experience gained throughout their years in the diamond trade. For visits to our laboratory, you can set up an appointment with us through our facebook page, in order to properly assess whether your diamond is actually synthetic (man-made) or natural.
