I like CZ jewelry to look real, not overly large. The .25 ct Sterling Silver Round CZ stud earrings measure almost 1/8" in diameter, a size I prefer for CZ stud earrings.  These CZs have a nice sparkle to them; the stem measures 3/8" long not including the CZ. The butterfly backs are small & a little hard for me to handle, but once on the earring they stay in place. If you find the backs too loose, use tweezers to pinch the round ends a little closer together. I suggest going slowly with this or you might get them too close together & you won't be able to get the earring stem through.  I've been wearing these earrings every day for  two months now & haven't had any problems with them.

At $6.79 with Super Saver Shipping, I think these earrings are a great value.
