Gema&Co

Gema&Co positions itself squarely in the ethical jewellery space, using moissanite stones set in recycled precious metals for engagement rings handcrafted in the USA. Their collection covers solitaires, halos, vintage-inspired designs, and custom pieces, with production usually running around two and a half weeks for standard orders.

The bespoke option lets you choose the stone shape, cut, colour grade, metal, and setting style with the help of their design team. Free shipping, a lifetime warranty, and straightforward returns make the international buying experience fairly low-risk. For buyers in Switzerland looking for a moissanite ring from a brand with a clear ethical framework, Gema&Co is a practical choice.
