How are lab grown diamonds made? Discover the two processes that'll help you answer the questions "How are lab-grown diamonds made?", CVD and HPHT. View All Diamonds Selective Seed Placement Artistry Ensured Our lab experts select the finest quality diamond seeds. It is most important to select seeds without any imperfections. Advanced CVD Growth Reactor Technology The diamond seed-laden disk is placed in a state-of-the-art growth reactor, where the Chemical Vapor Deposition (CVD) process works its magic. Controlled Growth Carbon Rain and Mastery In a span of 10 to 12 weeks, a controlled environment enables carbon atoms to rain upon the seeds, aided by gases, pressure, and temperature. Cultivated Diamonds Identical Properties Achieved Through the CVD process, rough diamonds are grown to possess identical chemical, physical, and optical properties as mined diamonds. Exquisite Craftsmanship Stunning Cultivated Gems Rough diamonds are expertly cut and polished to create stunning cultivated gems of exceptional beauty. Become a Grower/Partner Enquire now Get Inspired
