In the cannabis market, the word “diamonds” is used to characterise crystalline formations, particularly THCA, that form in sauce extracts or on their own. The word “diamond” has several different connotations when referring to cannabis. It’s frequently used to characterise crystalline forms of pure tetrahydrocannabinolic acid (THCA), commonly referred to as “THCA diamonds” or “THC diamonds,” and THCA that has formed in the presence of a terpene-rich solution. The non-psychoactive cannabinoid known as THCA, or tetrahydrocannabinolic acid, is a precursor to THC, or tetrahydrocannabinol, which is a psychoactive cannabinoid.
