Thank you for viewing. These are bororo's dumortierite in quartz earrings. They feature needle-like crystals encased in transparent quartz. The smoky blue color gives a mysterious impression. I love them, but I can't seem to wear them well, so I'm offering them for sale in the hopes that someone else will appreciate them. Thank you. ■Size Stone: H approx. 14mm x W approx. 9mm x D approx. 7mm Please note that there may be some error due to amateur measurements. ■Material Post: K18YG Stone: Dumortierite in quartz ■Used about twice.
