Moissanite Santa Hat Stud Earrings in 925 Silver

A Santa hat stud is a novelty earring, and the novelty is the point. The red hat and the Santa theme are readable at stud scale, which is why this design works where more complicated seasonal shapes turn into a blur. They are small enough to wear to work or a family dinner without looking like fancy dress, and they sit flat against the lobe, so there is nothing to swing or snag.

The stones are moissanite, set in 925 sterling silver. Moissanite has a refractive index of about 2.65, higher than diamond's 2.42, so the stones flash with more coloured fire than a plain glass or resin novelty earring. It also rates 9.25 on the Mohs scale against diamond's 10, so a seasonal pair that spends eleven months in a box comes out looking as sharp as it went in. The base is silver, so there is no brass underneath to turn green in storage.

The range covers several sizes, backs and finishes. Stud sizes run from 3mm up to 6.5mm, and each is offered with a push back or a screw back. Push backs are quicker to fit and remove. Screw backs grip more firmly and suit anyone who is hard on their earrings or wears them for long days. The finish is white gold or yellow gold. White gold is the cooler choice and contrasts well against the red, while yellow gold is warmer and more festive.
