Solid gold is guaranteed to never tarnish, so you never have to take it off (bonus: you can wear it in water). It's 100% worry free. In addition to our quality standards, all our manufacturers certify where their gold comes from so we can proudly stand behind our ethical practices.

The Icons speak to your individuality and celebrate the art of personalization. Featuring distinctive drop shaped natural gemstones like labradorite and aventurine as well as hand-set pavé, these pieces are the perfect blend of design and craftsmanship. At the core of the collection lies the Drop pendants, a canvas for creativity to stack on hoops or necklaces. Embrace an ever-changing collection and unlock a new jewelry language.
