Fluorite (QR Code) – Qinglong Mine, Dachang, Qianxinan, Guizhou, China
 One of the now extremely rare QR Code fluorites from a find at the beginning of this millennium.
 Fluorite, whose growth has led to skeletal tiled cube surfaces, on crystalline quartz.
 The unique design lies in the irregular, staggered arrangement of cube-shaped individual pieces. A corresponding tiling creates an overall appearance reminiscent of a so-called QR code.
 This parquetted surface structure of the fluorites resembles the square coded source code for product identification and therefore these crystals were called "QR-code fluorite".
 Beautiful small specimen of a QR Code Fluorite, which is now very rare and offered at top prices on the market.
