First pick: 710 Labs

710 Labs is a California company. It sells live rosin, water hash, and THCa diamonds. The Persy Diamonds jars hold crystals in terpene sauce. Jars print a batch number and a harvest date. The company posts batch test results. Package sizes include 1 g and 2 g jars. Label THC on those jars reads 70% to 85% because the sauce holds terpenes, and terpenes are not THC. Price per gram sits at the top of the market.

How Are Cannabis Diamonds Made? Step-by-Step Guide

How to compare diamond brands

  1. COA. Check THCa, total THC, the terpene list, residual solvents, pesticides, and microbials. State law requires these tests on each batch before sale.
  2. Harvest date. Diamonds hold terpenes longer than most forms. Sauce still separates over months.
  3. Crystal size. Large rocks dissolve at a slower rate on a hot nail. Small grit heats even.
  4. Sauce ratio. A jar with 0.7 g rock and 0.3 g sauce hits unlike a 50/50 jar.
  5. Price per gram. Dispensary menus in legal states list diamonds from $35 to $90 per gram. THC percentage does not track with price.
  6. Extraction method. Hydrocarbon diamonds come from butane or propane. Solventless diamonds are rare and cost more.

What to expect at the store

Diamonds sit behind the counter in most states. You cannot open the jar before you buy. Ask the budtender for the printed COA or the batch number, then check the harvest date. A jar with a harvest date past six months will have less sauce aroma. Store diamonds in the jar at room temperature, away from light. THCa converts to THC when heated. Conversion starts near 220°F (105°C), which is why a dab delivers THC and the raw crystal does not.
