Screw backs keep these studs secure, so you can wear them all day without checking that they're still there. Each earring is a cluster of round brilliant-cut moissanite stones in a claw setting, which lets more light reach the stones than a closed setting would. The base metal is 925 sterling silver. You can choose a silver finish or a gold-plated finish. Four designs are offered, about 10mm or 11mm across depending on the style. The supplier lists the earrings as unisex, and they are sold as a pair. A common question is whether the gold finish will wear off. Gold plating on sterling silver slowly thins with friction, lotions, and water. Keeping the earrings dry and storing them on their own makes the color last much longer. If the plating does wear through after years of wear, the metal underneath is still solid 925 silver, not a base metal that can turn your skin green. Moissanite is also one of the hardest gemstones, so the stones won't scratch or cloud with everyday wear. If you want the sparkle of a statement stud at a fraction of the cost of diamonds, these are worth considering. They stay put through workdays, workouts, and nights out, and each pair arrives ready to give as a gift.
