THCA Diamonds are formed from live resin – which aids in terpene retention – that allows for a more flavourful concentrate! The live resin, while still in a viscous state, is sealed in a pressurized container and left at room temperature. As time passes within this mixture, THCA crystals begin to form and fall to the bottom of the jar, creating diamonds. The residual terpenes found in the live resin rise to form a viscous layer on top before it gets seperated. The result: a solid concentrate comprised of 97-99% THC.
