Aquamarine Necklace, Diamond Art Deco

Stepped shoulders, a bezelled centre, and a hard horizontal line: this one borrows its geometry from 1920s plaque brooches. A 4 mm round aquamarine sits flush in a bezel at the middle, with diamond-set steps stacking outward on either side.

A bezel rather than prongs is what makes the reference work. The collar stands slightly proud of the stepped field, so across a 13.88 mm front the blue is the one raised point on an otherwise flat, hard-edged plaque.

Choose 16 inch or 18 inch. Each length is its own finished necklace on a solid cable chain in the metal you choose, so you are buying the length you pick.

The piece for someone who owns architecture books and dislikes anything that dangles.

The aquamarine is natural. Aquamarine is routinely heated to settle its colour, a permanent and industry-standard treatment, and these stones should be assumed heated.

Where the design carries diamonds, the accent diamonds are natural, never lab-grown or simulated, and are supplied to a published colour and clarity spec.

Gemstone and diamond carat weights are nominal totals and are approximate; actual weight may vary slightly from the stated figure. Millimetre measurements are nominal and vary piece to piece within normal manufacturing tolerance.
