Impressive Large Aquamarine Cocktail Ring, 30 Carats, Art Deco style and 0.80 Marquise Diamonds in 18k White Gold

A spectacular Art Deco style aquamarine and diamond cocktail ring, centred by an exceptionally large rectangular step-cut aquamarine of 30 carats.

Measuring approximately 22 × 15 × 12 mm, the aquamarine displays a striking, intense blue colour with excellent presence and the crisp architectural geometry characteristic of a classic emerald cut. Its considerable depth gives the stone an impressive saturation of colour, shifting beautifully between vivid blue and cooler crystalline tones as the light changes.

The aquamarine is secured by four substantial corner claws and flanked on each shoulder by a pair of marquise-cut diamonds, approximately 0.80 carat total. The diamonds form elegant leaf-like motifs within an openwork setting, providing a refined contrast to the strong geometric form of the central stone.

Crafted in 18ct white gold, the design has a distinctly Art Deco-inspired character: bold proportions, clean symmetry and an unapologetically impressive central gemstone.

A superb statement ring whose appeal lies not simply in the aquamarine’s substantial carat weight, but in its combination of scale, colour and elegant period-inspired design.
