What Are Lab Grown Diamonds?
Laboratory-grown diamonds are a new source of diamonds grown on Earth. They are the same as diamonds extracted from the ground – chemically, physically and optically. According to the Federal Trade Commission's (FTC) Jewelry, Precious Metals, and Pewter Industry Guidelines: "Diamond is a mineral composed primarily of pure carbon crystallized in an isometric system. The FTC revised the definition of diamonds, which were previously "natural minerals.". The Guide states that the Commission no longer uses the term "natural" to define "diamond", as it is now possible to define diamonds as "natural" diamonds when it is now possible to produce products that have essentially the same optical, physical and chemical properties as diamonds mined. (Source)) When carbon atoms crystallize into a cube structure with tetrahedral bonds, diamonds form, making it the hardest substance on Earth. This concept is used to grow diamonds on Earth using a high pressure, high temperature (HPHT) process or a chemical vapor deposition (CVD) process. Diamonds only grow when "diamond seeds" are present. A diamond seed is a very thin piece of diamond on which carbon atoms are deposited to form a powerful tetrahedral structure and grow into larger rough diamonds.
Are hpht diamond bad?
Absolutely not. Hpht is a real diamond. It has the same physical properties and chemical composition as natural diamonds. Compared to natural diamond mining, cultivating diamonds is more environmentally friendly. It does not require mining and can protect the surface environment, greatly reducing land consumption and carbon emissions (for natural diamonds). 1/2 of mining) and water resources (only 1/7 of natural diamonds), etc.; and it is significantly better than natural diamond mining in terms of labor protection, and there are very few safety accidents in the plant for cultivated diamonds.
