They wear as everyday studs rather than occasion pieces. Our guides to gothic earrings and earring types cover where a stud like this sits among the alternatives.\u003c\/p\u003e\n\u003ch2\u003eThe Lab-Grown Ruby\u003c\/h2\u003e\n\u003cp\u003eRuby is corundum — the red variety — and corundum is a 9 on the Mohs scale, second only to diamond. Our guide to what ruby means covers the history behind it, and garnet versus ruby is worth reading if you are deciding between the two.\u003c\/p\u003e\n\u003cp\u003eThese stones are lab-grown, with the same chemistry, hardness and optical behavior as mined corundum, in a saturated pigeon-blood red that would be scarce and expensive in nature at matched sizes across a pair.\u003c\/p\u003e\n\u003cp\u003eEach center stone is marquise cut and set north–south, the most elongating orientation — the same reasoning our guide to marquise cuts sets out for rings applies here.\u003c\/p\u003e\n\u003ch2\u003eMetal and Stones\u003c\/h2\u003e\n\u003cp\u003eBoth earrings are solid 925 sterling silver with a black ruthenium finish — a platinum-group metal that settles to a deep gunmetal rather than a flat black. The slight reflectivity is what keeps the milgrain and the star readable instead of flattening them.\u003c\/p\u003e\n\u003cp\u003eSmaller lab-grown ruby marquises form the rays and the point below the frame, so the red runs through the whole earring rather than sitting in one spot. The white accents — the halo of rounds around the frame, the pavé along the upper edge, and the stone in the star — are cubic zirconia.
