Sunset Tourmaline

Sunset tourmaline is a trade name for gem elbaite displaying warm sunset colors, blending orange, pink, peach and red. The hue may be a single warm tone or a soft gradient that recalls the colors of an evening sky.

The coloration is driven mainly by manganese, which produces pink and red, sometimes combined with elements or zoning that add orange and golden warmth. Some stones are bicolor, with distinct orange and pink zones.

It is valued for its lively, romantic color and is part of the broad family of warm-toned tourmalines that also includes peach and orange varieties.

Sunset tourmaline forms in granitic pegmatites from the boron-, lithium- and manganese-rich fluids that remain at the end of granite crystallization. Manganese gives the pink-to-red base, while subtle changes in chemistry produce orange overtones and zoning.

Crystals grow in miarolitic pockets with quartz, feldspar and other colored tourmalines, and warm colors often grade into pink or other hues along a crystal.

Sources include Brazil, Nigeria, Mozambique, Madagascar and Afghanistan, among other colored-tourmaline localities.

Sunset tourmaline has the characteristic striated prismatic habit and rounded triangular cross-section, hardness 7-7.5, vitreous luster, white streak and no cleavage.

Its warm orange-pink color combined with strong pleochroism helps distinguish it. The presence of color zoning or gradient is a clue that it is natural tourmaline rather than a single-color imitation.

Warm tourmalines can resemble some garnets, topaz or citrine; tourmaline's strong pleochroism and double refraction help separate it from singly refractive garnet, while its hardness and habit distinguish it from softer stones.

Sunset tourmaline is used in rings, pendants and earrings for its cheerful, warm color, appealing to those seeking orange and peach-pink gems. Bicolor sunset stones are especially distinctive.

Fine, saturated stones with attractive color blends command good prices, though warm tourmalines are generally more affordable than top blue cuprian material.

Metaphysically, warm-colored tourmalines are linked to energy, warmth and the sacral chakra, claims that are traditional rather than scientific.
