To keep your jewelry looking its best, avoid exposure to water, perfumes, and chemicals. Store your pieces in a dry place and clean them regularly with a soft cloth. For more tips, visit our Jewelry Care page ❤︎

When adjusting your adjustable ring, please handle it with care and only when necessary. Too much pressure can deform the delicate handmade design. A gentle touch will keep it looking beautiful. 💍✨

Our rings are made from conflict-free materials. We use high-quality conflict free simulated diamonds, which are man-made stones that look just like diamonds and shine brilliantly ✨

No have to worry, our rings won't turn your finger green :)
