- Materials:
- 18k Solid Gold: Crafted in 100% recycled 18K solid gold, this piece is made from gold all the way through — not plated, coated, or filled. With 75% pure gold content and an Au750 hallmark, it is designed for everyday wear, lasting value, and a warm glow that never fades.
- 18k Gold Over Sterling Silver: Made with a 1-micron layer of 18K gold over genuine sterling silver — a thicker gold layer than standard plating, which is often only 0.01–0.05 microns. Stamped S925, with no brass or copper core.
For solid gold version, our earring back is also crafted from solid 18K gold, ensuring safe and worry-free wear.
