This vintage EFFY ring is crafted in solid 14K yellow gold and set with alternating diagonal rows of dark blue topaz and diamonds across the crown. The stones are laid in angled channels separated by raised polished gold ribs, so the band reads as a continuous spiral of blue and white rather than a static row, and the ribs catch light between each row to frame the color. The deep inky blue of the topaz plays hard against the brilliance of the diamonds, and the warm yellow gold pushes both tones forward. The crown carries a gentle dome that tapers smoothly into a slim comfortable shank, giving the ring presence on the finger without bulk. It is marked 14K and BH, the maker's mark of BH Multi, the manufacturing house behind EFFY, used on the brand's earlier production. EFFY built its reputation on hand-finished settings and heavily saturated colored stones, and this piece shows that approach in miniature. A striking stacking band or standalone statement piece.
