The Hayat Gems Journal

Tourmaline forms in more colours than almost any other gemstone — green, pink, blue-green Paraiba, and naturally zoned watermelon bi-colour among them — while remaining durable enough (7–7.5 on the Mohs scale) for daily-wear jewelry. That combination of colour range, durability and design flexibility is why it has become one of the most sought-after coloured gemstones for custom rings, earrings and pendants.

Each colour variety has its own character: Green Tourmaline is the classic, widely available entry point; Paraiba Tourmaline is the rarest and most valuable, prized for its neon blue-green saturation; Watermelon Tourmaline is collected specifically for its natural pink-and-green zoning, with no two stones alike. Whichever you’re drawn to, natural gemstone value comes down to the same fundamentals: colour saturation, cut quality, clarity to the eye, and — for higher-value stones — certification.
