" These earrings are very small, maybe somewhere between 3 and 4mm each. They do appear white, (I don't see any yellow tinting) with a slight, slight bit of grey, which I prefer over a super white look (as you might sometimes find in a cz). These earrings catch the light nicely, showing a bit of rainbow effect. They aren't super, super sparkly or faceted, but they do possess shine and detail. I am very happy with these earrings as they are just what I wanted: something petite and real, set in yellow gold, and with a nice, clean and "believably" sparkly look! I also like the fit of the earrings backs, very tight and secure. "
