These are stones I found at my parents' house. Some have issues, but I'm selling them all together. There's amethyst-like stones, like those used for "sazare-ishi" (small stones used in shrines), and some finely crushed stones. I was told a jeweler gave them to my parents, but they never used them, just displayed them in a glass case. When I had them appraised for purchase, the green stones were suspected to be glass, not jade. The rose quartz is old, and the beautifully cut, sparkling stones that look like amethyst appear to be glass. I don't know what the yellow, rod-shaped stones are. The jade floor decoration was displayed in the alcove, but it broke. I think it could be displayed again if professionally repaired. The purple glass, which looks like amethyst, has a beautiful finish, so I think it could be used as a necklace pendant if you add metal fittings. I'm selling them all together. Thank you.
