The listing, ONE OF A KIND -- Double Terminated Crystal Point Ring has ended.
I believe my mother had this ring made. It is quite large and very unique. As it is hand-made, there are no markings. But I have had it tested and it is sterling silver.
The crystal alone measures 1 1/4" long. It is a size 7.
Crystal have many meanings for many belief systems, from wicca, to magick, to pagan. This ring was meant for someone special an as unique as my mother was.
I have a few other rings from her estate, take a look.
