Stern, the Rio de Janeiro house renowned since the mid-twentieth century for pairing richly colored Brazilian gemstones with sculptural, hand-finished goldwork. The hallmark sits cleanly on the interior shank, consistent with the house's standard practice of marking both maker and metal content on its gold pieces.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003eThe amethyst itself is a deep, saturated purple with strong color zoning visible under raking light, faceted in a traditional oval mixed cut that throws broad, even flashes across the table. Eye-clean to the naked eye, the stone reads dark and velvety in its upper half and opens to lighter violet tones near the culet, giving the face-up view real depth rather than a flat, uniform purple.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003eWhat sets this piece apart is the bezel treatment: rather than a smooth rim, the gold is built up from tightly coiled rope-twist wire wound in parallel courses around the entire perimeter of the stone, with a polished gold ball accent at each shoulder where the shank curls upward into the coiled bezel. The reverse is left open in a pierced gallery, allowing light to pass through the pavilion and brighten the stone from behind, a detail that also lightens the overall feel of what is otherwise a substantial, dimensional ring. The stone itself is held by a six-prong basket integrated into the coiled framework, distinct from the decorative ball elements at the shoulders.\u003c\/div\u003e\u003cdiv\u003eAt nearly 9 grams of 18k gold and centered on a stone of real size and presence, this is a ring meant to be noticed on the hand, combining H. Stern's textural signature with an amethyst that holds its own against the goldwork surrounding it.\u003c\/div\u003e","brand":"H.
