General Description
Tourmaline is one of the most diverse gemstones in nature. It can appear in nearly every color of the spectrum—from vivid pinks and deep reds to emerald greens, ocean blues, and even black. Some crystals display multiple colors within a single stone, such as the famous watermelon tourmaline, which shows a pink center surrounded by a green rim.
Varieties and Colors
Richly colored, gem-quality (pink, green, blue, multicolored)
Schorl: Black or very dark brown (common)
Dravite: Brown to dark yellowish-brown
Rubellite: Deep red to pink
Indicolite: Blue to blue-green
Verdelite: Green
Watermelon Tourmaline: Pink center with green rim
Paraíba Tourmaline: Electric blue to neon green (copper-bearing, extremely valuable)
Major sources include Brazil, Afghanistan, Madagascar, Nigeria, Mozambique, and the United States (California and Maine)
