Rubellite Tourmaline: Why Not All Pink Tourmaline Earns the Rubellite Name

by Laura Konst
Not all pink Tourmaline is Rubellite. The name is reserved for material displaying a saturated, stable red to pink colour that holds its character across different lighting conditions, a standard that depends on the precise balance of manganese and iron within the crystal structure. This guide explores the pegmatite geology, the manganese colour chemistry, the role of iron in disqualifying otherwise pink material, and where Rubellite sits within one of the most colour-diverse mineral families on Earth.

Black Tourmaline: The Mineral That Generates Its Own Electricity

by Laura Konst
Black Tourmaline, known mineralogically as Schorl, is one of the most common black minerals on Earth and a defining species of the tourmaline group. Formed within boron-rich pegmatites and metamorphic rocks, its deep opaque colour, complex chemistry, and remarkable piezoelectric properties make it one of the most mineralogically fascinating crystals you can add to your collection.
