I've worn it about 10 times. The beads are approximately 6mm, 5mm, and 4mm in size. The type of stone is unknown. It will be shipped without a box, wrapped in bubble wrap. I have taken the photos in natural light. The color may differ from the image depending on the lighting. Thank you for your understanding. ⚫ There is a smoker in the house (smoking is only outdoors), and there is a cat. ⚫ It may take some time to reply to messages and ship items. Please take a moment to read my profile, if you don't mind.
