What Are THC Diamonds?

THC diamonds are crystalline structures of pure, concentrated THCA–that means they aren’t actually THC! THCA turns into THC when it’s heated. This process, known as decarboxylation, is necessary in order to experience the psychoactive effects of cannabis. Technically, diamonds can be made from just about any cannabinoid, but the most popular are THC and CBD.

How Are THCA Diamonds Made?

THCA diamonds are made in one of two ways: a closed-loop system or a solvent-evaporation technique known as the crystalline method. Both methods involve multiple steps and professional equipment, so do not attempt to make diamonds at home by yourself.

Closed-Loop: As with other concentrates, a closed-loop extraction method uses a solvent to push cannabinoids and terpenes from the marijuana flower. Once those important compounds are isolated, the solvent is removed. Where diamonds differ from other concentrates is that with diamonds, the solvent must be removed very slowly. This gives the THCA something to grab on to and start to form crystals around. The closed-loop system can take as much as a few weeks to complete. 

Crystalline: This technique follows the same process as the closed-loop system, except when it is time to remove the solvent, both heat and pressure are applied to help the solvent evaporate. This causes the THCA to form into crystals which then sink to the bottom of the solution. There, they will form with any other THCA structures. 

When both of these processes are complete, you’re left with hard, crystal-like structures known as diamonds. Because of the time and effort that goes into the process to make THC diamonds, they tend to cost more than your average concentrate.

How Do THC Diamonds Differ from Concentrates?

THC diamonds are a type of cannabis concentrate, as THCA is isolated and extracted to create a concentrated form of the cannabinoid.

What’s the Difference Between THCA Crystalline vs. Terp Sauce?

THCA crystalline and terp sauce are actually quite similar. After all, terp sauce contains THCA crystalline. The difference is, however, terp sauce also contains a liquid bath of terpenes. THCA diamonds, on the other hand, are literally pure THCA with no other cannabinoids, terpenes, or flavonoids in them. You can have terp sauce with THCA crystalline in it, but THCA crystalline cannot be terp sauce.

How Are THC Crystalline Diamonds Consumed?

The only way to turn THCA diamonds into THC is to heat them, so most cannabis enthusiasts consume them by dabbing or vaporizing them. Some people actually add their diamonds to liquid terpenes to enjoy the flavor of the terpenes because pure THCA does not really have a taste or aroma to it. That being said, if you prefer your cannabis not to have an odor, THC crystalline diamonds could be a great product for you.

Because THCA will convert to pure THC when heated, it’s important to remember that this is an incredibly potent concentrate. A little goes a long way, so start slow and with a low dose and adjust from there to your tolerance levels.

FAQs About THC Diamonds

This unique cannabinoid is the source of many questions in our dispensaries. Here are a few of the most popular queries.

Are THC diamonds decarboxylated?
When you purchase a THC diamond, it is not decarboxylated. However, when you vape or dab the THC diamond, it will activate the cannabinoids, turning THCA into THC.

Are THC diamonds hard? 
While these crystalline concentrates look like precious gems, they are easy to break into small pieces. This makes it easier to portion out your THC diamonds to fit your concentrate needs.

Are THC diamonds potent? 
Yes! THC diamonds are concentrated forms of THC, so they are extremely potent.
