• They’re made through complex lab processes using solvents and slow crystallization that should not be attempted at home. Depending on how they’re made, they might be paired with terp sauce for added flavor and entourage effects.
  
  
• You can find THCA diamonds at licensed dispensaries, and it's best to check for purity, clarity, and freshness. A little goes a long way, so start small and enjoy the ride. Store them in a cool, dark spot to keep them potent.
  
  

THC Diamonds

Also: THCA Diamonds, Liquid Diamonds, THCA Crystalline

Diamonds are a type of cannabis concentrate that earned its name due to its crystalline appearance. Available as both a solid and a liquid, these popular extracts are extremely potent, so it’s important to fully understand THC diamonds before partaking.

THC diamonds are crystalline structures of pure, concentrated THCA, meaning they aren’t actually THC! So, while we’ll be referring to this product as “THC diamonds” in this article, bear in mind that they are actually “THCA diamonds.”

THCA activates and turns into THC when it’s heated through a process called decarboxylation. For example, smoking THCA diamonds in a dab rig or infused joint is enough to decarboxylate them and achieve the desired effects of THC. On the other hand, if you eat a THCA diamond without first decarboxylating it, you won’t experience the same effects.

THC diamonds appear crystal-like and translucent–hence the name “diamond.” The color of the crystals can range from clear to shades of amber, with less opaque THC diamonds generally indicating higher quality. Other names for THC diamonds include: 

• Weed diamonds
• THC crystalline
• THCA crystals
• THCA diamonds
• Diamond sauce
• Liquid diamonds THC
  
  

THC diamonds, after decarboxylation, can contain upwards of 99% THC, which is far higher than the 60-90% THC content of other cannabis concentrates.¹ However, diamonds' high THC content doesn’t guarantee a more powerful psychoactive effect than other concentrates.²

According to a CU Boulder study, high-potency concentrates may provide more THC, but they won’t necessarily cause more intense psychoactive effects than regular flower.³ This is due to a phenomenon known as the entourage effect, where the cannabis plant’s terpenes and cannabinoids work together to produce more enhanced effects.

THC diamonds can be made using the closed-loop technique or the crystalline method.⁴ Both methods involve extracting cannabinoids from cannabis or live resin with solvents and purifying the extract to make diamond THC. 

Here’s a high-level look at how cannabis concentrate manufacturers produce THC diamonds. Remember that making concentrates is very complex and dangerous, so do not ever attempt this at home.

The closed-loop method for making THC diamonds minimizes waste by recycling solvents to produce pure THCA crystals. The process involves: 

• Extraction: Manufacturers flash-freeze cannabis flower and use solvents to extract cannabinoids and terpenes.¹
  
  
• Purification: Solvents are purged from the extract to create a thick cannabis concentrate. Next, they freeze the concentrate to filter out solidified waxes and get a refined cannabinoid and terpene-rich concentrate.
  
  
• Crystallization: The technicians use a nonpolar solvent to dissolve the purified concentrate. As the mixture slowly cools, it separates into a liquid terpene-rich “sauce” and chunks of THCA crystals.
  
  

The final step is diamond mining, which involves filtering the THC diamonds from the sauce. Some producers sell the sauce separately as a terpene-rich extract or coat the diamonds with the sauce to give them flavor.

The crystalline or solvent-evaporation process for making THC diamonds typically involves the following steps:

• Extraction: Manufacturers create live resin concentrate by extracting cannabinoids and terpenes from flash-frozen cannabis flower.
  
  
• Filtration: They then mix the concentrate with ethanol, freeze it, and filter it to remove impurities, such as waxes, lipids, solvents, and particulate matter.
  
  
• Diamond Mining: The purified concentrate is mixed with a nonpolar solvent, which is gradually cooled or evaporated until THCA crystals form and separate from the liquid (sauce).
  
  

While both methods may seem similar, they rely on different equipment and techniques to create THC diamonds. 

Again, do not attempt to make diamonds at home. Even the slightest mistake while handling volatile solvents can lead to fire accidents, chemical burns, or exposure to toxic fumes.

Solid crystalline THC diamonds can be consumed several different ways:

• Dab Rig: After heating a dab rig, place a small amount of THC diamonds on the heated nail or banger to smoke the concentrate. 
  
  

• Smoking: Whether you’re rolling a joint or packing a bowl with ground flower, you can place a small amount of THC diamonds on top of the flower. When the joint or bowl is lit, the diamonds will combust with the flower to produce a potent smoke.
  
  

• Dab Pen: Place a small piece of the diamond in the concentrate chamber. After setting the device to the recommended temperature (around 315-450℉), the dab pen will heat the diamonds, releasing their potent vapor for consumption without combustion.⁵
  
  

• Edibles: butter or cannabis-infused oil can be enhanced with THC diamonds, which then can be used in your favorite edible recipe.
  

Due to the difference in consistency, consumption methods for liquid diamonds are going to be different. First, make sure you have a dab rig or dab pen that is compatible with liquid concentrates. For best consistency, liquid diamonds should be at room temperature.

• Dab Rig: Once you heat the dab rig’s nail, you can add a small amount of liquid diamonds to the heated nail or banger, where they will vaporize.
  
  

• Dab Pen: After adding the liquid diamonds into the dab pen, the liquid diamonds will heat and vaporize the concentrated vapor.
  
  

• Vape Cartridge: Many dispensaries carry liquid diamonds in vape cartridge form, which can be screwed onto your battery and enjoyed the same as a distillate vape.
  
  

You now know what THC diamonds are, but how are they different from other cannabis concentrates? Here’s a summary of the other key differences between THC diamonds and popular cannabis concentrates.

THC diamonds 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 and other cannabinoids. 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 diamonds in it, but THCA diamonds cannot contain terp sauce. 

While diamonds are THCA-rich and relatively flavorless, terp sauce is overflowing with various cannabinoids and flavorful terpenes. This makes diamonds ideal for a potent THC experience without the taste or smell of cannabis.

In addition to high cannabis concentrations and potency, both THC diamonds and shatter also can be consumed by smoking, vaping, or edibles. The primary difference between the two is in its physical state: shatter is hard like glass but is also easily breakable. THC diamonds, on the other hand, are small, difficult to break, and shaped like diamonds.

It’s easy to see the difference between THC diamonds and crumble: diamonds are clear and look like precious gems, and crumble looks like a crumbly chunk of feta cheese. Crumble is less potent and is preferred more for its taste than potency, whereas diamonds are preferred more for their potency and lack of a distinctive flavor.

You can buy THC diamonds at most dispensaries and cannabis shops. You will need to prove you’re old enough to legally buy cannabis, so don’t be surprised if the budtender asks for your ID. Also, depending on your state’s marijuana laws, the dispensary may ask for your medical card before selling you THC diamonds.

A state-licensed dispensary is the best place to buy diamonds because they stock only legally compliant, accurately labeled, and third-party-tested cannabis. Get the best quality product by checking diamond THC for the following before purchasing:

• Quality and purity: It should have a lab test certificate that verifies it’s contaminant-free with a pure THCA content of at least 99%.
  
  
• Color and appearance: High-quality diamonds are typically clear or milky.
  
  
• Age: THC diamonds that are older than 12 months may be less potent.
  
  

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

What are THC diamonds?

THC diamonds are a crystallized cannabis concentrate with a THCA content of over 99%, leaving little room for other cannabinoids. Diamonds also contain little to no terpenes, resulting in a mostly neutral taste and smell when smoked or dabbed.

Are THC diamonds decarboxylated?

No. 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 THCA with a purity of over 99%, making them extremely potent. Heating the THC crystals in a dab rig or vaporizer activates the THCA, turning it into THC that can cause powerful psychoactive effects.

Can I make diamonds or liquid diamonds at home?

No. Not only is it extremely dangerous–requiring both specific equipment and flammable solvents–but depending on your location, producing cannabis concentrates may be legally restricted.

Are THC diamonds the most potent form of cannabis?

THC diamonds are among the most potent forms of cannabis if you want a strong THC experience. However, if you prefer a fuller cannabis experience that includes other cannabinoids and terpenes, diamonds may not be your best choice.

How do you use THC diamonds?

Cannabis lovers typically enjoy diamonds with dab rigs or dab pens. These devices evenly heat the THC crystals and release THC-loaded vapors that you can inhale. Alternatively, you can sprinkle ground diamonds on flower to smoke in joints, pipes, and bongs.

What's the difference between THC diamonds and live resin?

THC diamonds are crystals of concentrated THCA that become THC when heated. The diamonds contain zero or only trace amounts of terpenes and other cannabinoids. Live resin, on the other hand, is a liquid cannabis concentrate filled with cannabinoids and flavorful terpenes typically found in marijuana plants.

How long do THC diamonds stay potent?

With proper storage, THC diamonds can retain their potency for six to 12 months, after which the concentrate’s THCA content will begin degrading. Preserve your THC diamonds’ potency by storing them in an airtight container placed in a cool, dark cabinet.⁹

Why are THC diamonds sometimes called sauce?

Some people call THC diamonds “sauce” or “liquid THC diamonds.” However, these names are misleading because the “sauce” is the terpene-rich liquid that forms during the diamond production process. 

You can find THC diamonds mixed in with the sauce under labels like “diamond and “sauce” or simply “sauce” for short.

Can you eat THC diamonds?

You can’t eat THC diamonds directly, but you can use THC diamonds when making edibles–they just need to be decarboxylated first.

Ready to Try THC Diamonds?

If you want a highly potent THC product without cannabis’s taste or smell, THC diamonds are a great choice. Each diamond is at least 99% pure THCA, which turns into THC when you light it up in a joint, pipe, vaporizer, or dab rig.
