Black Diamond weed isn’t quite as rare as its namesake precious gem, but you may have almost as much difficulty finding this potent indica-dominant hybrid strain. Seeds were never released, so any producer wanting to grow them has to find clones — not an easy task.

If you can find it, you should try it. Black Diamond, also called Black Diamond OG and Black Diamond OG Kush, delivers a happy and sometimes-trippy head high, and a calming, sometimes-sedating body buzz that stress and many pain patients love. Couples love it as well, as this strain is often praised for its aphrodisiac properties.

Black Diamond delights the senses with berries, musk, and earth all prominent in its pungent aroma and flavor. The flower is odd-looking but it’s one of the most beautiful strains of weed, showing strangely-shaped curly leaves and often large streaks of purple.

Effects and Side Effects

Black Diamond’s head and body highs set in almost at the same time. As euphoria floods the brain, the user’s core and extremities begin to feel heavy. Relaxation hits all over the body at the same time, with stress disappearing and muscles loosening.

The cerebral effects aren’t energetic or creative but tend to induce feelings of happiness and mental relief. Giggling and laughing aren’t uncommon, and users are likely to become more talkative and sociable. The brain buzz encourages fun conversation, relaxed enjoyment, and as we’ve mentioned, sex can also be on the menu.

Depending on the amount of weed consumed and THC tolerance, mild hallucinogenic visual and sound effects are quite possible when using Black Diamond. They’re not overwhelming, but they can be startling if you’re not expecting them.

Meanwhile, the body is experiencing its own peaceful, gentle relaxation thanks to the strain’s strong indica content. It’s mellow but not usually couch-locking, at least at first. As the high winds down, though, drowsiness and sleep are likely to arrive.

Black Diamond is known to make anxiety worse in patients already experiencing the issue, with paranoia and panic also possible. The same side effects may appear with overuse of the strain, as may more disturbing hallucinations. These aren’t a given, but they can happen.

This weed is quite likely to give users cottonmouth and dry eyes, and dehydration is another common effect of Black Diamond. You’ll need munchies during the high — and they should always be accompanied by plenty of water.

Positive Effects:

  • Energy: 2/5
  • Creative: 2/5
  • Pain: 4/5
  • Stress: 4/5
  • Sleep: 3/5
  • Mood: 5/5

Negative Effects:

  • Paranoid: 3/5
  • Dry Mouth: 5/5
  • Dry Eyes: 5/5
  • Lethargy: 3/5
  • Cough: 3/5

Bottom Line: Black Diamond can be a fun strain to use, with happy and social cerebral effects that may turn hallucinogenic, and a body stone that’s relaxing but not overly sedating for a while. It’s a terrific evening strain that can lead to fun in bed as well.

Medical Conditions

Its stress-relieving properties make Black Diamond a favorite among patients with access to the strain. Mental health issues like clinically-diagnosed stress, anxiety, and depression are among the conditions that users say can be relieved with Black Diamond, although it’s not always suitable for anxiety patients because of its high THC content. It may help ADD patients, too.

Those suffering from insomnia find the strain extremely helpful because of the sedative effects that eventually appear during use. And patients say the relaxation provided by Black Diamond, along with possible sedation, is extremely good for muscle aches and chronic pain. Some have found those effects can help with more serious pain as well.

Flavor and Aroma

This is a pungent weed with the overriding scent of berries, thanks to its tart and acidic Blackberry parent strain. Some say they can smell grapes, but the aroma is that of wine grapes, not the sweet fruit. There’s plenty of earthiness and musk underneath, along with some nuttiness.

Black Diamond rich smoke is similar, but the earth balances out the berry sweetness quite well. Expect a pleasant aftertaste of berries and toasted nuts.

Flavor and Aroma Ratings:

  • Earthy: 3/5
  • Citrus: 1/5
  • Fruity: 4/5
  • Spice: 2/5
  • Wood: 3/5

Cannabinoids and Terpenes

Average THC content often doesn’t always tell the full story of a strain. Black Diamond tests at an average of about 16%, but it’s not uncommon for batches of this rare weed to have THC levels as high as 20-24%. Of course, if you can find it, you shouldn’t hold out for a more potent flower. CBD and CBN content can vary considerably, ranging from very low to well over 1%.

The many types of terpenes that can be found in cannabis are well-represented in this strain. Linalool and geraniol provide berry and flowery properties, caryophyllene and camphene contribute a little pine and spice, and myrcene and phellandrene are also prominent.


Black Diamond was reportedly created in Northern California, but the identity of the breeder isn’t known. It’s a cross of Blackberry and Diamond OG; Blackberry is an obviously-delicious balanced sativa/indica, and Diamond OG is a strongly indica-dominant strain that delivers strong, long-lasting body relaxation and sedation.

This weed doesn’t fall far from its parent plants.

Similar Strains

Some of the best strain comparisons to Black Diamond are Blueberry OG, Strawberry Cookies, Mango, and Afgoo. Tahoe OG Kush might be a better choice if you’re looking for stronger sedative effects.

If the flavor is more important to you, Southern Lights and Mag Landrace might be more to your liking. Patients say that Southern Lights is a more potent medicinal strain.

Black Diamond Strain Review: FAQ

Q: When you say that Black Diamond is a “rare” strain, does that mean it’s just difficult to find? Or is it impossible?
A: “Impossible” is a very strong word, but it may be closer to the truth than “difficult.” There is Black Diamond weed out there, but it can take a long and diligent search to find it. Online word-of-mouth may be a better approach than simply visiting dispensaries in your area on a long and possibly unrewarding quest. Those living in or visiting California could have the best luck.

Q: In that case, can you grow it on your own?
A: Once again, finding it could be the biggest problem. It’s said that Black Diamond seeds were never made available and that finding a clone was the only alternative if you want to grow the plants yourself. However, some reputable seed banks like Pacific Seed Bank claim to sell these seeds; it’s not known if they’re the real deal or an attempt to come close to the original strain. It’s said to be a moderately-easy crop to grow, though, so if you strike gold (or should we say diamonds) — good luck!
