Unusual vintage natural clear faceted quartz w/ amethyst cap. Size 7.5 💜

This is a very unusual vintage handmade ring in size 7.5. It’s made from natural clear quartz crystal with a amethyst cap. Not sure of the metal since it isn’t marked. There is a slight anomaly on the second to the last picture, probably due to the age of this piece, but in overall good preowned condition. Please see all photos for measurements, details and current condition. Thank you for looking and all sales are final 💙💜
