The Curator’s Note

On Colour: The true magic of Yaogangxian fluorite is notoriously difficult to capture on camera due to its light-reactive nature. In person, under natural or display lighting, the teal tones are richer, deeper, and even more luminous than photographed.

On Authenticity: As a 100% natural, earth-mined product, minor geological imperfections, rugged edges, and asymmetrical growth patterns are to be expected. These are the signatures of its authentic journey over millions of years. Please review all photos and dimensions carefully before securing this piece.

Frequently Asked Questions

What is Yaogangxian fluorite? Yaogangxian is a tungsten and tin mine in Chenzhou, Hunan Province, China, that has become world-famous among mineral collectors for producing exceptionally well-formed cubic fluorite crystals in a range of colours including teal, blue, green, and purple. Specimens from this locality are considered among the finest fluorite in the world.

What makes cubic fluorite special? Fluorite crystallises in the isometric (cubic) system, producing perfectly geometric cube-shaped crystals. Sharp, well-defined cubic fluorite with high clarity and vivid colour is highly prized by collectors and commands premium prices at mineral shows globally.

What is the teal-blue colour caused by? The colour in fluorite is caused by trace impurities and radiation-induced defects in the crystal lattice during formation. Teal and blue fluorite from Yaogangxian is particularly rare and valued for its unusual hue.

Is fluorite a gemstone or a mineral? Fluorite (calcium fluoride, CaF₂) is a halide mineral. While it can be faceted as a gemstone, collector-grade specimens like this are valued for their natural crystal form rather than as cut stones.

Is this piece natural and untreated? Yes — 100% natural, earth-mined fluorite. No dyes, coatings, or enhancements of any kind.

Do I receive the exact piece shown? Yes. This is a one-of-a-kind specimen; the photos show the exact piece you will receive.

Please Note

• Crystals are natural products — minor surface variations, inclusions, and asymmetrical growth are part of their character, not defects.
• Macro photography is used to highlight detail; please refer to measurements for true scale.
• Colour may appear slightly different under different lighting conditions — teal fluorite is particularly light-reactive.
