Synthetic HPHT Diamonds as Diamond-Bearing Rock Pseudoindicators

A comparison between synthetic HPHT diamonds and natural diamonds has been conducted, highlighting substantial differences between them. Key distinctive features of synthetic HPHT diamonds have been identified, facilitating their differentiation from natural counterparts. The authenticity of HPHT diamonds found in rocks from the Ukrainian crystalline shield has been examined. Samples from concentrates of crystalline and terrigenous diamond-bearing rocks, exhibiting similarities to synthetic HPHT crystals, serve as pseudoindicators of diamond potential in geological formations and necessitate thorough investigation.
