Cannabis Diamonds: The Short Answer
Cannabis diamonds are pure THCA crystals. They look like rough-cut quartz, they test high, often 90% THCA or better, and they carry almost no flavor on their own. The crystals form when extractors let a concentrate sit long enough for the THCA to separate from the terpenes and other oils around it. What's left behind is a pool of liquid terpenes called sauce and a pile of hard, glassy rocks. You dab them, usually with a little sauce on top for taste. Heat converts the THCA into THC, which is the part that gets you high.

How the Crystals Form
Most diamonds start as a hydrocarbon extract, though some producers work with ethanol or rosin. The extractor dissolves the crude oil in a solvent, filters out plant matter, then purges the solvent off under vacuum. What's left goes into a sealed jar and into a temperature-controlled oven. Over days or weeks, the jar gets cycled through warm and cool stages. THCA has a habit of stacking into lattices when it's given time and the right conditions, so it slowly drops out of solution as solid chunks while the terpenes and flavonoids stay liquid. Good labs pull the jars at the right moment. Pull too early and you get a gritty slush. Pull too late and the sauce dries out.

Diamonds vs. Sauce
They come from the same jar, so the comparison is a bit like asking about the cereal versus the milk. Diamonds are the THCA: hard, near-tasteless, and potent. Sauce is the terpene layer: runny, aromatic, and much lower in THC. Some brands sell them together as "diamonds and sauce," which is the version most people actually want. Diamonds alone give you a blunt, powerful hit with little flavor. Sauce alone gives you flavor and a mellow effect. Together they cover both.

What Diamonds Feel Like
Since the active material is THCA, the raw crystal won't do much if you eat it. Heat is what makes it work. Once you dab it, the effect tends to hit fast and land hard, more in the head than the body for a lot of people, though that depends on the strain the extract came from. New users should treat one small piece as a full dose. A grain of rice is a reasonable starting point, and even that can be a lot if your tolerance is low.
Dabbing Them Right
You need a rig, a banger, a torch, and a carb cap. Quartz bangers work well because you can see the puddle and judge the temperature. Heat the banger until it glows, then wait. How long depends on the thickness of your quartz, but 30 to 45 seconds is a normal range. Drop the diamond in, cap it, and pull slow.
Temperature matters more with diamonds than with most other concentrates. Too hot and you scorch the terpenes and cough through the whole hit. Too cool and you leave a puddle of unvaporized oil behind. A cheap infrared thermometer takes the guessing out of it. Aim for somewhere around 480 to 560 degrees Fahrenheit. Cold starts are another option: load the diamond first, then heat the banger until the oil starts to bubble, and cap it.
Storing Them
THCA crystals are fairly stable, but the sauce around them is not. Terpenes evaporate, oxidize, and go flat. Keep the jar sealed, keep it in a cool dark place, and skip the fridge unless you're holding it for months. If you do refrigerate, let the jar come to room temperature before opening it, otherwise condensation drops moisture straight into your concentrate. A glass jar with a tight lid beats silicone every time, since terpenes migrate into silicone and never come back.
What to Look For When You Buy
Ask for the lab report and read the THCA number, not just the total THC. A jar labeled 95% THC might be mostly THCA on the actual test. Look at the sauce too: it should be glossy and smell like the strain, not like hay or solvents. Clear, chunky crystals sitting in a decent pool of amber sauce is the sweet spot. Dry rocks rattling around in a jar with no sauce usually mean the batch sat too long.
Who Should Skip Them
If you're new to cannabis, or if you mostly smoke flower, diamonds are a big jump. They wreck tolerance quickly, and the high can feel one-dimensional without the terpenes to round it out. Anyone with a low threshold, or anyone who wants to taste the plant, is better off with live resin or a good rosin. Diamonds are a tool for people chasing maximum potency per hit, and that's about it.
