AMMA's Filligree earstuds Frame - bold ánd delicate and made of 18 carat gold. Filigree is an ancient lace-like metal technique. During the process of working with this ancient technique, the contrast between a bold minimalistic frame and the delicate and detailed ornaments of filigree was intriguing. Both in shape and technique, the tension between them is strong and difficult to balance. When in balance they look stunning together.
