If you've looked at the little crystal clusters in our case and wondered whether they're actually as potent as they look — they are, but there's a small technicality worth knowing before you use them. What you're looking at isn't quite THC yet. It's THCA, THC's non-intoxicating precursor, crystallised into a near-pure form. Heat is what finishes the job.
So what's the difference between THCA and THC?
THCA is the acidic compound cannabis actually produces. It doesn't get you high on its own. Heat it — by dabbing, smoking, or vaping it — and it converts into THC through a reaction called decarboxylation, at which point it becomes intoxicating. That's why diamonds are sold as crystallised THCA even though everyone calls them "THC diamonds": the name describes what they become the moment you use them, not what's sitting in the jar.
Why are they so strong?
Diamonds are made the same way live resin is — starting from cannabis extract pulled with a hydrocarbon solvent — but instead of stopping there, producers let the solution sit under controlled conditions until the THCA crystallises out on its own, sometimes over days or weeks. What's left behind is a terpene-rich liquid called "sauce," which is often sold alongside the diamonds or recombined with them. The crystals themselves commonly run 90–99% THCA purity — about as concentrated as cannabis gets. (If you want the fuller breakdown of how this compares to live resin and distillate, we covered that in an earlier post.)
How do you actually use them?
There are a few real options, depending on what gear you've got:
- Dabbing. The traditional route — a small piece goes on a heated nail or banger in a dab rig, and you inhale as it vaporises. Lower temperatures tend to preserve more flavour; higher temperatures give bigger clouds at the cost of taste.
- A loadable vape pen. If your pen is built for concentrates (not a sealed disposable), a small amount can be loaded directly and heated the same way.
- Sprinkled onto flower. A few crystals dropped onto a packed bowl, bong, or into a joint before lighting will decarboxylate from the heat of the flame as you smoke, boosting the potency of a regular session.
- Already-infused products. This is the easiest route by far — some vape carts and pre-rolls come with diamonds already built in, so the conversion happens automatically when you use the product as normal. No measuring required.
One thing diamonds aren't good for: eating raw. Without heat, there's no decarboxylation, so raw crystals dropped into food won't do much. If you want an edible-style effect, that heating step has to happen first.
Where to find them on our menu
We carry diamonds two ways — on their own, and already built into a few of our vape carts:
