Large Blue Cap Tourmaline A850

Blue Cap Tourmaline – Rare Collector-Grade Termination

A beautifully saturated blue-cap tourmaline showcasing that classic two-tone transition collectors obsess over. This piece displays a deep, inky black-green body with a vivid electric blue termination, highlighted dramatically when backlit. The cap glows with that unmistakable tourmaline translucency that sets true blue-caps apart from ordinary schorl.

The crystal shows excellent natural texture and growth striations along the body, culminating in a concentrated blue zone at the top where the color intensifies and lights up under a strong light source. Blue-cap terminations of this quality remain scarce on today’s market—especially in unpolished, natural form like this.

Geological Note

Blue-cap tourmaline forms when late-stage pegmatitic fluids introduce a different chemistry during the final moments of crystal growth, allowing the termination to shift into rare blue wavelengths. This zoning is both geologically uncommon and visually striking—making each specimen one-of-a-kind.
