Sapphire Cabochon Ring – Atelier MJM, 14K Yellow Gold 585 (6.10 g, Size US 7.25 / EU 55 / 15)
The velvety depth of rich blue, the sleek lines of a smooth cabochon cut, and retro elegance inspired by 1960s and 70s design. Weighing 6.10 g, this exceptional ring was crafted from 14K yellow gold (585 hallmark) at the renowned Atelier MJM studio. The piece represents a prime example of Polish artisan goldsmithing, where modern minimalism intersects with a nostalgic vintage touch and quiet luxury.
At the heart of the composition lies a natural sapphire in a smooth cabochon cut, boasting an intense, captivating hue. The stone’s rounded, polished form pairs effortlessly with the substantial gold setting, releasing soft light reflections that create a deep contrast against the warm tone of 14K yellow gold. An ergonomically contoured band in size 15 / 55 (US 7.25 / 17.5 mm) ensures a comfortable fit on the finger—making it a bold daily accent or a treasured addition to an artisan jewelry collection.
