Lab Grown HPHT & CVD Diamond
This chart shows the different methods of diamond growth and an example of their rough form!
Diamonds grown with the CVD or HPHT method are all real diamonds! Both methods produce diamonds that are physically, optically, and chemically identical to natural diamonds although they may have unique characteristics before they are cut and polished as seen in the figure above. Both types are made of pure carbon and create the same hardness. To the naked eye, there are no clear differences between a CVD and HPHT diamond and the price for each option are very similar.
What are lab-grown diamonds?
A lab-grown diamond is a lab-grown diamond whose composition, physical, chemical and optical properties are the same as those of a natural diamond, so it cannot be distinguished by the naked eye, a magnifying glass or even a microscope. There are currently two mainstream cultivation methods: chemical vapor deposition (CVD) and high temperature and high pressure (HPHT).
Lab-created diamonds are changing the game for jewelry retailers, with a sustainable and ethical option. These diamonds, which are distinct from mined diamonds in that they were grown by man but remain chemically, physically and optically identical to those dug out of the ground. There are two primary methods to create lab-grown diamonds: HPHT – High Pressure High Temperature, and CVD – Chemical Vapor Deposition. This article gives you a complete view of the processes used and their importance in lab-created diamond manufacturing. Diamonds deposited by the HPHT process are chemically and physically identical to natural diamonds. Often specific to industrial use, HPHT diamonds are becoming more popular in jewelry applications.
The popularity of lab-grown diamonds is increasing, as awareness grows amongst consumers about the positives they can bring. Technological developments mean that the quality of and price for these diamonds is continually improving, increasing their appeal to consumers as well making them suitable for a wider range of industries.
