Tourmaline
Why does tourmaline often have multiple colors in one crystal?
Tourmaline's multi-colored appearance stems from changes in the chemical environment during crystal formation. As the crystal grows, varying amounts of trace elements are incorporated into its structure, creating distinct color zones. This is most famously seen in watermelon tourmaline, where pink and green zones occur in the same crystal. The phenomenon, known as color zoning, can create dramatic effects like sharp color boundaries or gradual transitions within a single specimen. Each multi-colored piece tells the unique story of its formation conditions.
How can I tell if my tourmaline is natural or synthetic?
Natural tourmaline typically shows slight irregularities in color distribution and may contain natural inclusions visible under magnification. The colors should appear rich but natural, without an artificially vivid or perfect appearance. Multiple colors in a single crystal often indicate natural formation, especially if the color transitions are irregular or asymmetrical. Additionally, natural tourmaline displays pleochroism – showing different colors when viewed from different angles. While synthetic tourmaline exists, it's relatively uncommon compared to other synthetic gems.
What's the best way to clean and care for tourmaline?
Tourmaline requires mindful care to maintain its beauty. Clean your crystals using warm water and mild soap, avoiding ultrasonic cleaners or harsh chemicals. Dry thoroughly with a soft cloth after cleaning. Store tourmaline pieces separately from harder stones to prevent scratching, ideally in soft pouches or lined boxes. Avoid sudden temperature changes and prolonged sun exposure, as some varieties may fade in strong light. While tourmaline is relatively durable (7-7.5 on the Mohs scale), it can be sensitive to pressure, so handle with care and avoid impacts that might cause internal stress or fractures.
Tourmaline fascinates with its remarkable color diversity, appearing in virtually every hue of the rainbow – often within a single crystal. Our collection features premium specimens showcasing tourmaline’s most coveted varieties, from the watermelon-hued bi-color crystals to the vivid pink of rubellite and the deep blue-green of indicolite.
