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.

About zircon
Zircon is a natural mineral, not the synthetic cubic zirconia. It is 6 to 7.5 on the Mohs scale and brittle, so its facet edges wear or chip easily when zircons rub against each other or against other gems.
Cleaning
Warm water, a drop of mild dish soap and a soft toothbrush are all you need. Brush behind the stone too, where dust and skin oils collect, then rinse and dry with a soft cloth. An ultrasonic cleaner is usually fine for a clean faceted zircon, but skip steam: sudden heat can crack it or change its color.
Wear and storage
Never keep zircons loose together in one bag: rubbing wears their facet edges. Store each one on its own in a gem jar or a soft pouch, and protect it from knocks.
For your jeweler
This zircon is untreated. Zircon takes normal setting well, but keep it out of direct torch flame: sudden heat can crack it or change its color.
