Thank you for viewing. This is a very valuable gemstone. It's a type of quartz that contains red, sparkling, glitter-like inclusions of lepidocrocite. Fire quartz, Sacred Seven, and Super Seven are well-known examples, but this loose stone features a faint pink color with lepidocrocite inclusions within transparent quartz. Firstly, transparent pink quartz of this quality is rarely seen (the quartz in this product is a pale pink color). Furthermore, I've only ever seen one other piece with lepidocrocite inclusions like this. It's an ultra-high-quality piece. This precious loose stone has been set into a pendant top with a brilliant oval cut. High-quality fire quartz spheres of about 12mm can cost hundreds of thousands of yen, so I believe this is a very good value. I am selling this as part of a decluttering effort. I hope it reaches someone who will cherish it. *Chain not included. Pendant top only.* Please assess the condition based on the photos. Thank you for viewing. I also handle pendant tops of rare stones such as rutilated quartz, lepidocrocite, and rhymar, so please take a look.
