Natural Stone Materials Handmade Materials Accessory Materials Fluorite Faceted Rice Cut Approx. 8x6mm Sold by the strand (19 beads) (Decorative beads are not natural stones) High-quality fluorite faceted cut beads. Although small, they are transparent and very beautiful. The Japanese name "Hotaru-ishi" (蛍石, fluorite) comes from the fact that when thrown into a fire, it crackles and emits fluorescence, scattering about. In addition to heat, some fluorite exhibits beautiful and mysterious luminescence through "fluorescence" caused by ultraviolet light. The range of colors is very wide, with purple, green, colorless, light blue, yellow, indigo, and pink being the most common in order of abundance, which seems to be influenced by the differences in the rare earth elements they contain. Some even have stripes of various colors. Among them, the blue-violet, white, and yellow striped fluorite from Derbyshire, England, is called "Blue John" and was processed into vases and ornaments in the 18th and 19th centuries, gaining popularity. ❗️Please read the profile before purchasing or making inquiries.
