Oval Aquamarine Necklace, Diamond Deco Halo (7x5mm center)

Baguettes are what separate this from an ordinary halo. A 7 by 5 mm oval aquamarine sits in four prongs, ringed by baguette-cut natural diamonds across the top and bottom with a column of round brilliants down each side, so the surround has flat facets and fan-shaped rays rather than a plain bead border.

One third of a carat of diamonds goes into that ring, and the baguettes are why the 16.1 mm pendant throws broad flashes instead of fine sparkle. The two cuts do different jobs and the contrast is visible at arm's length.

It hangs on a solid cable chain, in the metal you choose, that adjusts between 16 and 18 inches, so you set the drop where you want it.

For an anniversary where the recipient already owns the obvious pieces and would notice the baguettes.

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.
