Materials Used: ・Surgical Stainless Steel (Gold) ・Rutile Quartz 5mm ※All stud earrings come with catches made of the same material. In the 8th photo, I've circled the areas with cracks. There are some white line-like cracks, but personally, I don't think they're very noticeable. If you don't mind, I'd be happy to send them to you (,,ᴗ ͜ ᴗ,,) ☆Even a single one is simple and cute, and those with multiple ear piercings can enjoy them too♪ ✔ Inclusions and cracks are characteristics found in natural stones. We hope you enjoy them as a one-of-a-kind item. Please refrain from purchasing if you are looking for perfection. ✔ Macro photography makes the colors appear darker than they actually are. Please refer to the other images for the actual colors, as the close-up shots are for checking the patterns “(. .*) ✔ Thank you for your understanding of handmade items.
