Laboratory stones are one of the most controversial and exciting innovations in the world today. They began to grow diamonds more than 60 years ago for industrial purposes. General Electric (USA) was the first to synthesize them in large quantities in 1954. The technology imitated the natural process of stone formation, the so-called HPHT (High Pressure, High Temperature - "high pressure and high temperature", 1,300 ° C and a pressure of about 50,000 atmospheres). In parallel, the industry began testing another method: CVD (Chemical Vapor Deposition). Today, all laboratories that grow stones use one of these two. Larger stones were obtained by those who use the HPHT technology.

Until recently, grown stones were called "synthetic", therefore, they were not seriously compared with precious stones extracted from the earth. In 2018, the US Federal Trade Commission (an independent consumer protection agency) approved new naming rules for the jewelry industry. Diamonds are now considered to be mined and grown stones. It is now incorrect to call laboratory stones synthetic diamonds. They have the same chemical and optical properties. They are diamonds. Modern grown diamonds cannot be distinguished from natural ones without special devices. They are certified by gemological laboratories, issuing a passport - as well as mined stones. If you want to buy lab grown diamonds in dallas, you may come to store.
