Moissanite Stud Earrings, 0.1ct to 4ct in 925 Silver

This is a stud range built around one idea, which is that carat weight should be your decision and not your budget's. Every stone is round brilliant cut moissanite on 925 sterling silver, and the sizes run from a tiny 0.1ct up to a large 4ct. The cut and the setting stay the same across the range, so the only thing that changes is how much stone you see, and that makes it easy to compare one size against another.

Moissanite is silicon carbide, hard at 9.25 on the Mohs scale and with a refractive index of about 2.65 against diamond's 2.42, so it gives more fire than a diamond of the same size. The stones are sold as test passed, which means they register on a thermal diamond tester, though an electrical tester will tell the two apart. They are not diamonds, and the lower price reflects that, but they hold up like a serious stone.

Match the carat to the diameter. The 0.1ct is 3mm and sits quietly on a second piercing. The 0.3ct at 4mm and 0.5ct at 5mm are everyday sizes. The 0.8ct at 6mm and 1ct at 6.5mm are the pair people usually settle on. The 4ct at 10mm is a statement stone and needs a lobe with room. Choose a yellow gold or a white gold finish to suit your skin tone and the rest of your jewellery.
