Review on 2Pairs 18K White-Gold Plated Sterling Silver Round Square Cubic Zirconia Simulated Diamond Stud Earrings For Men Women - Milacolato by Amy Cummings

FWIW, I got the 4mm size, which I usually use for my extra hole. I have some black pearl earrings that these will go well with, sort of complementing the iridescence of the pearls. I like the sparkly dark stones.The square version is noticeably larger than the round version, roughly another mm. This means that if you wanted to line up multiples of increasing size, this might work nicely.
