This 1950 Art Deco style custom-made platinum cluster ring centres on a light blue elongated oval cut 4.00 carat aquamarine. The gemstone sits within a rubbed over milgrain border and is surrounded by a halo of twelve brilliant cut diamonds, accompanied by two baguette cut diamonds set east to west on the shoulders splitting into two sets of six brilliant cut diamonds, bringing the total diamond weight to 1.40 carats. Full UK hallmarks for platinum 950 appear on the band. Measuring 1.8 cm high, 1.5 cm wide, and 2.2 cm deep, the piece is worn upon the finger as a statement accessory. The design incorporates silver tones from the metal alongside white diamonds and the central pale blue stone. The finger band transitions smoothly to the decorated face, offering a sophisticated addition to formal evening attire or everyday wear.

FAQs

An Art Deco style aquamarine cluster ring typically features a prominent central light blue gemstone surrounded by geometric or halo arrangements of diamonds, set in white precious metals with detailed millegrain edging.

These rings are traditionally crafted from platinum or white gold to enhance the cool blue tones of the central aquamarine, accented with brilliant-cut and baguette diamonds.

Authentic period pieces exhibit historic metal purity hallmarks, precise hand-applied millegrain decoration, period-correct gemstone facet proportions, and structured platinum settings.

An aquamarine cluster ring acts as a refined statement piece that complements contemporary tailoring, neutral colour palettes, and modern minimalist fine jewellery combinations.

Clean gently using warm water, mild soap, and a soft brush, avoiding harsh chemicals or extreme thermal shock to protect the clarity of the natural gemstone.
