Since then, several other methods have been developed to create lab-grown . Both methods are commonly used, but CVD is becoming more popular for producing gem-quality synthetic diamonds for jewelry.An obvious difference in genuine and synthetic diamonds are how they are produced.Both laboratory-grown gems (also called “synthetic” gems) and natural gems that look like a particular gem can be used to imitate that gem.
Lab-Grown Diamond Production Methods
This process involves subjecting graphite to high pressures and temperatures to convert it into diamond. Younger buyers find synthetic diamonds especially appealing, and not just because of lower prices. HPHT is used more often to create synthetic diamonds for . Diamond simulants are not diamonds, but are stones that are somewhat similar in appearance and are generally used for cheaper, high street .The jewelry industry uses special terms for manufactured and look-alike materials: synthetic (man-made, lab-grown or lab-created) and imitation (simulants). These diamonds are also associated with human rights abuses. Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. In fact, it is impossible to tell a CVD diamond apart from a .Identification.
