Today there’s a lot of talk around synthetic diamonds. But what are they, how are they made, and in what ways do they differ from natural, mine-sourced diamonds? Synthetic (aka man-made, lab-grown, or cultured diamonds) are formed in highly controlled lab environments using the same basic raw material as natural diamonds – carbon. Whereas natural diamonds were formed through geological processes over billions of years, synthetic diamonds are created through production methods such as high-pressure high-temperature (HPHT) or chemical vapor deposition crystal formation (CVD). Learn more about how synthetic diamonds are cultured, their properties, relative valuation, and the techniques Sarine has developed to distinguish them from natural diamonds.
