Rough Amethyst and Diamond Dress Ring

A circa 1970 dress ring in 18ct yellow gold, set with a rough amethyst crystal and accented by a single diamond. The design is built around the natural form of the stone, with an open textured gold surround that gives the piece a bold, sculptural profile. The amethyst has a saturated violet tone with an irregular crystalline surface that catches light in a more fractured, uneven way than a cut stone. A curved gold band crosses the front of the crystal, while the surrounding goldwork adds movement and structure around the centre. It is a strong statement ring with a distinctly seventies character. The contrast between raw amethyst, polished gold and the small diamond detail gives it a confident, unconventional look that feels collectible and visually striking on the hand.
