How are lab grown diamonds made?
Lab grown diamonds are produced in an artificial setting that imitates the natural process of the Earth’s mantle. One of the main methods of creating a lab diamond is CVD (chemical vapor deposition) while another method, HPHT (high pressure high temperature).
Both methods are effective in creating high-quality diamonds that look and feel the same as those found in nature.
CVD lab grown diamonds
During the CVD diamond creation process, a minuscule slice of diamond is placed into a chamber where it is exposed to carbon-rich gas and heated to extreme temperatures. Within a period of just weeks, the carbon gas ionizes and the resulting particles stick to the original diamond slice, before eventually crystallizing into a fully formed diamond.
Most experts agree that the process of creating CVD diamonds vs HPHT diamonds creates slightly higher quality gems. This is because the HPHT process involves metal, which can enter the diamond and cause more visible inclusions. When the HPHT process is used, pure carbon is pressed within a metal cube, exposed to extreme heat and pressure through electric pulses.
Eventually, that carbon will break down and crystallize into a diamond. All metal traces within an HPHT diamond are tiny and are usually invisible to the naked eye.
HPHT lab grown diamonds
The HPHT method (high pressure and high temperature), is the original method used in creating lab grown diamonds. This method works to recreate a diamond’s natural growing environment naturally found deep within the earth. in the HPHT method a diamond seed is placed in a specifically designed press, once pressed the seed material is moved to a growth chamber. The growth chamber is then heated to 1300-1600 °C with pressures above 870,000 pounds per square inch. The molten metal created by this process dissolves the high purity carbon source. Carbon atoms precipitate onto the diamond seed crystal, and a synthetic diamond begins to grow. Once the lab grown process is complete the newly created crystal is then cut and polished by a diamond cutter.
Certified lab grown diamonds
Certified lab grown diamonds go through strict grading assessment during certification. Certification labs like GIA, EGL and IGI grade lab grown diamonds to the same quality standards as natural diamonds.
This means you can filter your diamond search by the usual cut, color and clarity standards, so you can find a lab grown diamond equally as beautiful as a top-quality natural diamond.

Lab Grown Diamond FAQs
Just like Natural Diamonds, All Lab Grown Diamonds come with an Appraisal which will allow you to insure your diamond against loss, damage, or theft.
Absolutely Not! In fact, the only way anyone can identify a Lab Grown Diamond including the Major Grading Laboratories is by using Specialized Sophisticated Equipment.
All Certified Lab Grown Diamonds are laser inscribed on the Girdle of the diamond with the number of the corresponding grading certificate.
Lab Grown Diamonds are typically 70%-80% Less Expensive than Natural Diamonds for the exact same size and quality.
Consumers can purchase a Larger Diamond for Substantially Less Money than a natural diamond of the same size, shape, and quality.
