USA, Utah: Tiffany stone is a gemstone often patterned with swirls or sections of purple, white, black, yellow, and violet-blue. The stone is mostly fluorite, but also has variable levels of other gemstones mixed in, such as quartz and opal. Some consider this gem a fluorite variety. This pretty piece was made from a large specimen I slabbed. Set in a high wall sterling silver bezel. Chain not included.
