Antique French Marquise Diamond Ring

This exquisite antique marquise diamond cluster ring, crafted in Paris circa 1900, is a testament to timeless French artistry. At its heart lies a 0.5-carat marquise-cut diamond, set in a delicate millegrain bezel. Surrounding the central stone are small old mine-cut diamonds, arranged in an elegant navette-shaped cluster, collectively glistening with their characteristic charm.

The ring is crafted from 18K gold and platinum, with the hoop in rich yellow gold and the bezel topped in contrasting platinum—a hallmark of early 20th-century French jewellery. The finely detailed open gallery features repeating crescent motifs. All diamonds are set in open-backed settings, ensuring maximum light reflection and brilliance. The cluster head measures approximately 12 x 6 mm.

The piece is marked with the French 'eagle's head' control mark, indicating its Parisian origin and 18K gold purity. Weighing 2.14 grams, it is a light and delicate treasure, perfectly proportioned for those seeking understated elegance.

The ring is a UK size H (US size 3.75). It remains in very good condition, with all stones securely set and the gold retaining its polished finish.
