Rare as a diamond, this strain is hard to find but reportedly worth the search. Black Diamond, a cross between Blackberry and Diamond OG, has trichome-covered buds with a purple tint and grape smell packing up to 26% THC and nearly 4% CBD, according to seed bank Bonza Seeds.
 
It tastes earthy and sweet with a slight skunky odor, as expected given its lineage.
 
Effects are uplifting then relaxing, even tending toward drowsy, according to Bonza.
