Emerald Cut Moissanite Necklace, 1ct to 3ct in 925

An emerald cut pendant looks different from a brilliant one at once. The facets are long, flat and stepped, so instead of sparkle you get clean bands of light and dark, a calm, architectural look. It shows the stone more openly, which is why the cut tends to suit people who prefer understated jewellery. Because the outline is a long rectangle with clipped corners, it also lies flat and neat against the chest and does not twist or roll as a round stone sometimes does.

The stone is moissanite, which has a refractive index near 2.65 against diamond's 2.42, so even a step cut gives more flash than you might expect. At 9.25 on the Mohs scale it is hard enough to keep its large flat facets free of scratches, which is the thing to protect on an emerald cut, since flat surfaces show every scuff. The chain and setting are 925 sterling silver, so the metal will not tarnish the way plated brass does.

Choose 1ct, 2ct or 3ct. The 1ct is a slim, quiet pendant for a work wardrobe. The 2ct is the balanced middle and the most popular choice. The 3ct is bold and needs an open neckline. The chain is 40cm with a 5cm extension, so it sits high on the collarbone at the short setting and drops lower when extended, which gives you two lengths from one necklace. Finishes are silver colour, gold colour and rose gold colour.
