Ask a jeweler how to spot fake Tiger Eye and they'll usually point to one thing first, weight and pattern consistency. Genuine Tiger Eye forms when quartz gradually replaced fibrous crocidolite, leaving parallel bands that shift and shimmer as the stone turns, a natural optical effect called chatoyancy that's genuinely difficult to fake convincingly in glass or resin imitations, since those tend to show a flatter, more uniform shine with no real depth to the movement.
The golden-brown color you're looking at here is the stone's natural, untreated state, no dye or heat treatment involved, unlike some of the blue, red, or black variations that circulate in the market and require processing to achieve.
That's part of why classic golden Tiger Eye remains the most trusted and widely traded version, buyers know exactly what they're getting without wondering what step happened in a lab before it reached a cabochon cutter.
Tiger Eye has also picked up an informal reputation as a birthstone alternative for those born under Leo and Capricorn, alongside its long standing use as a stone associated with courage, protection, and grounded confidence in crystal traditions.
Each cabochon here is cut mix shape with a flat back, and because the fiber density and banding width vary from stone to stone, the strength of the chatoyant flash shifts piece to piece even within the same batch.
