Diamonds are the crystalline structures that develop at the bottom of the container.
Concentrate enthusiasts will be familiar with sauce carts, or vape cartridges loaded with terpene-heavy sauce. These cannabis diamonds may also refer to the crystalline structures left over after terp sauce has been removed from the initial sauce mixture. These diamonds are usually coated in residual sauce and very potent.
Diamonds can also refer to pure crystalline THCA that have been isolated from refined oil. THCA is non-intoxicating on its own, but converts into the intoxicating THC when exposed to heat through decarboxylation.
When THCA diamonds are vaporized through a dab rig, e-rig, or vaporizer, THCA decarboxylates into the active THC, which in turn binds with receptors in the body’s endocannabinoid system to produce an intoxicating effect.
