Natural White Zircon 6.6mm 2.19ct Untreated Round Cut Interesting Fluorescence

A near-colorless round zircon with a softly misty interior and warm white to pale beige tones in natural light. Natural inclusions are present, consistent with the SI clarity grade, giving the stone a gentle, organic quality. What truly sets this specimen apart is its remarkable multi-spectral fluorescence: under 310nm shortwave UV it blazes a vivid orange-red, under 365nm longwave UV it shifts to a soft peach-pink glow, and under 255nm it takes on a gentle pink-lavender hue. This kind of multi-wavelength response is unusual even among fluorescent zircons, making it a standout piece for collectors.

Mined in Tanzania and sold entirely untreated, this stone's fluorescence is a completely natural optical property related to trace uranium content typical of certain high-zircon varieties. It is primarily a collectors' piece, prized by mineral enthusiasts, gemologists, and UV-reactive gem collectors who appreciate the science behind the spectrum. The Tanzanian provenance and untreated status add to its appeal as a natural history specimen as much as a gemstone.
