Rhodolite Garnet

Rhodolite garnet is a naturally occurring blend of pyrope and almandine garnet - typically about 70% pyrope (magnesium-rich) and 30% almandine (iron-rich). This intermediate composition produces the distinctive rose-to-raspberry color that distinguishes rhodolite from the darker, brownish-red of pure almandine or the lighter pink of pure pyrope.

Garnet forms in metamorphic rocks (particularly mica schists and gneisses) and in some igneous rocks. The specific pyrope-almandine ratio that produces rhodolite's color requires metamorphic conditions where both magnesium and iron are available in the right proportions. Rhodolite crystallizes as the characteristic dodecahedral or trapezohedral crystals of the garnet group.

Rhodolite's rise in popularity over the past two decades has been driven by discoveries in East Africa (Tanzania, Mozambique, Kenya) that provide vivid, well-saturated material at accessible prices. It offers a raspberry-pink color previously available only in much more expensive gems like pink sapphire or rubellite tourmaline.

Rhodolite is identified by its distinctive raspberry to rose-purple color, cubic crystal habit, hardness of 7-7.5, and garnet's characteristic lack of cleavage (it breaks with conchoidal fracture like glass). It's singly refractive with no pleochroism.

Distinguish from amethyst (lower SG, different crystal system), pink tourmaline (doubly refractive, prismatic crystals), and rubellite (darker, more saturated, doubly refractive). Rhodolite's combination of raspberry color, high luster, and single refraction is diagnostic.
