White opal is milky white and glossy, a very clean and beautiful power stone. It looks grayish in the photo, but it's actually closer to white. I apologize that I couldn't capture it well. As for its effects, it's a special power stone that contains water, and because it houses the power of "water," it's said to regulate the flow of luck and lead to happiness, enveloping the wearer. I've acquired a very good quality one. Since shipping is included, I think it's a great deal. Wrist size: 17cm Stone size: Approximately 10mm in diameter Due to being a natural stone, there may be dents or inclusions in the beads. Please understand this beforehand. [Carefully packaged and shipped with care] I am a company employee during the day, so my responses may be delayed. Thank you for your understanding.
