What are THCA diamonds, and should I try them?

Diamonds are crystalline, near-pure THCA — commonly 95%+ — that convert to similarly concentrated THC when heated. They are the strongest product category we cover, and the honest answer to "should I try them" is: not as a starting point. They exist for experienced, high-tolerance users with appropriate hardware; for anyone else the margin for overshoot is enormous. If you are in the experienced lane: verification is pleasantly simple (a purity claim either has a COA or it does not), and price per gram should be compared against other concentrates, not flower. Start low, go slow applies at double strength.
