Black Diamond X is Maven Genetics' XXX OG x Black Diamond OG cross, and it sits squarely in the OG lane: earthy musk, diesel and a savory finish on dense, colourful, trichome-loaded flower. Maven calls it a hard-hitting indica and describes total body relaxation running alongside a euphoric head buzz. For anyone who prefers fuel and Kush weight over candy, this is Maven's clearest statement.
Where It Comes From
Maven is a California operation, and Black Diamond X is listed among the Crown Jewels of its strain library — the house cultivars the brand builds around rather than one-off limited drops. Its staying power in the active flower, preroll and vape catalog matters for a practical reason: it did not vanish after a single release, which gave Maven room to use it as a breeding parent.
That second life is the more interesting part of the story. Black Diamond X sits on one side of a whole shelf of Maven releases: Fantasma (Runtz x Black Diamond X), Umami Butter (Gelatti x Black Diamond X), Chroma (Prizm x Black Diamond X), RS-X (RS-11 x Black Diamond X), Apples and Diamonds (Golden Applez x Black Diamond X), and Phantom X (Kush Mints x Black Diamond X).
Each takes the original's resin, musk and physical weight somewhere different — fruit, cream, mint, fuel.
The Cross
Maven Genetics gets both breeder and producer credit, and the strain library lists the cross as XXX OG x Black Diamond OG. XXX OG is Maven's own selection from XXX x OG Kush, which makes this a house-genetics project on at least one side. Black Diamond OG contributes the dark colour and dense Kush character the name promises.
Maven's description centres on earthy musk with diesel underneath and a savory character to match, and it holds from the first crack of the jar through the exhale. This is not a cultivar where bright top notes do the work.
Two specifics are worth watching for. The buds run genuinely colourful, green shifting toward violet or near-black against orange-to-amber stigmas. And the trichome coverage is heavy enough that well-grown flower reads sticky rather than dusty. Lemon rind, pine, pepper and floral Kush can appear around the core depending on batch and cure.
What It Left Behind
Its footprint is breeding influence: at least six Maven releases trace directly back to it, which is a real measure of a house cultivar's value even without a trophy behind it.
That is the argument for keeping a workhorse in the catalog. Limited drops move fast and disappear; a cultivar that stays in production long enough to be bred against becomes infrastructure, and half of Maven's modern shelf is standing on this one.
The High Rise Take
Black Diamond X is Maven's durable OG workhorse — earthy musk, diesel, dark frosted flower, and the euphoric-to-heavy arc the breeder itself describes. Menu listings have advertised THC as high as 33%; treat that as a result for one tested lot rather than a property of the cultivar.
