Black onyx combines with Clogau's inimitable 'Tree of Life' motif to stunning effect. Black onyx shines especially well when used as a backdrop for colour play. Here the natural luster of rose gold glows against polished onyx - perfect for evening wear. Notice too the exquisite yellow gold filigree detail. With a touch of rare Welsh gold, the oval Nightfall ring is delivered in a presentation box with a certificate of authenticity.
