Thank you for viewing! (^-^) Natural stone: Kyanite Bead size: Approximately 7mm Posts: Earring backs: Surgical stainless steel Discounts available for multiple purchases☆ This is handmade. I make every effort to create them carefully, but they are not comparable to mass-produced items. I hope you will handle them gently. As they are natural stones, they may have 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 if you have a moment☆彡
