Moissanite Hoop Earrings, 3mm to 4mm in 925 Silver

These are closed hoops set with moissanite rather than plain metal bands. A hoop presents stones on a curve, which means that at any moment part of the line is catching light head on while the rest glances. That is why a jewelled hoop looks livelier in movement than a stud of the same carat weight. The hoop sits close to the lobe rather than swinging, so it stays put under a collar and does not tangle in hair.

The stones are D colour moissanite, which is the top of the colourless range and the right call against a white metal hoop, because any warmth in the stone would read as yellow next to bright plating. Moissanite's refractive index of about 2.65 is higher than diamond's 2.42, so the fire is stronger, and 9.25 on the Mohs scale means earrings that live in a jewellery box with other pieces do not pick up scratches.

Three stone sizes set the weight of the pair. The 3mm is the most discreet and the easiest to wear every day, including to work. The 3.5mm is the middle ground and the one most people settle on. The 4mm gives the hoop real presence and reads clearly from across a room. Each size comes in white gold, yellow gold or rose gold plating over 925 sterling silver, and the hoops close with a hinged post and snap catch.
