Chunky Asymmetrical Clear Quartz? Bracelet Sterling Silver 925 Heart Clasp

Chunky Asymmetrical Clear Quartz? Bracelet Sterling Silver 925 Heart Clasp pre-owned bracelet. Good condition. I believe it is quartz, but I am not a professional. It was tested on my Presidium Gem Tester and it does not register as glass. It also is not plastic. Cold to the touch. Very pretty. No brand or maker's mark that I can see. Heart shaped clasp with 925 stamp. Thank you for your interest in my closet! Please feel free to reach out with questions. I am open to reasonable offers and love to bundle for a better deal!
