Origin & story
Rubellite is the trade name for tourmaline that remains a true red or raspberry pink under all lighting conditions, rather than browning under incandescent light.
Nigerian and Mozambican deposits have produced exceptional clean crystals. SOMSTONE selects rough for clarity and saturation and cuts to preserve colour.
