Quartz tinted by fine inclusions of iron oxide or goethite dispersed through the interior. Named, straightforwardly, for its resemblance to strawberry.

Found in Madagascar, Kazakhstan, and Brazil, though specimens with vivid redness are uncommon. Most lean closer to pale pink than red. Crystals that truly earn the name "strawberry" are limited. Between the colour the name promises and the colour delivered, a small gap.

Inclusion density and distribution differ from stone to stone, so no two share quite the same hue.
