Emerald-Cut Aquamarine Necklace, Diamond Halo

An emerald cut does not sparkle; it reflects. Long parallel steps send light back in broad flashes, which is why this 5 by 3 mm stone reads deeper and cooler than most of the rounds and ovals in this collection. Step cuts show colour darker than brilliants do.

The diamond halo around it is squared off with softened corners, so the outline stays rectangular where the stone is rectangular. One eighth of a carat of natural diamonds, four prongs at the corners, and a 9.55 mm pendant strung in line on the chain.

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.

For someone whose taste runs architectural rather than romantic: the emerald cut is the one shape that reads as design rather than sentiment.

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.
