Thank you for viewing! (^-^) A pale blue sheen floats on the milky white stone, a very beautiful stone. ~Cubic Zirconia (CZ)~ This artificial stone has a refractive index very close to that of a diamond, and it shines so beautifully that it is difficult for the naked eye to distinguish it. It has a brilliance similar to that of a diamond, but the dispersion of light (rainbow-colored brilliance) tends to be slightly stronger than that of a diamond. Natural Stone: Moonstone Bead size: Approximately 5.5mm Post: Catch: Surgical stainless steel ~We accept changes to the metal fittings~ Hook → Stud Stud → Hook, etc. Free of charge ☆ We offer discounts for multiple purchases☆ This is handmade. I try to make them carefully, but they are not as good as mass-produced products. I hope you will handle them gently. Since they are natural stones, there may be cracks or inclusions. I have several cats. Please refrain from purchasing if you are concerned. ・I am studying to polish natural minerals such as Larimar. My polishing skills are still developing, but thank you for your support (*´ー｀*) Please read my profile for more information☆彡
