This exceptional specimen features a sharp single crystal of genuine Ruby (the red variety of Corundum) from the famous gem fields of Tanzania. The crystal perfectly demonstrates textbook hexagonal symmetry, showing off a beautifully defined prismatic habit and a flat, clean termination.
This specimen features an exceptionally strong, brilliant neon-red fluorescence under a shortwave or longwave UV lamp. This fiery, electric-red glow is a definitive signature of high-quality, chromium-activated ruby crystals that carry minimal iron impurities to quench the fluorescence.
Perfectly scaled as a premium thumbnail-class specimen, this crystal comes pre-mounted on a clean white display insert securely housed inside a classic Perky box. Tanzanian rubies are highly celebrated by systematic collectors for their sharp crystallization and distinct crystal physics. With its outstanding geometry, clean faces, and explosive UV reactivity, this piece makes a vibrant, high-impact addition to any fine crystal or fluorescent mineral display.
