These Earrings came exactly as advertised. 3 pairs of (.925) sterling silver, cubic zirconium for $13.00, you can't go wrong. I'm not sure why some other reviews mention size. I don't know how Overstock.com could make the size any clearer.
They tell you they are 2mm, 3mm, and 4mm, and they even place them against a 1 inch scale to demonstrate size. If you want jumbo (5mm, 7mm, 9mm) sterling silver, cubic zirconium earrings, Overstock.com sell them too for only $7.00 more.
Approximate sizing info:
2mm= 0.06 ct or 1/16 ct
3mm= 0.125 ct or 1/8 ct
4mm= 0.250 ct or 1/4 ct
5mm= 0.500 ct or 1/2 ct
7mm= 1.00 ct or 1 ct
9mm= 3.00 ct or 3 ct
All ct weights are for one earring only, for the ct weight for the pair just double the ct numbers.
Now if you go for the jumbo size earrings, will your family and friends really think that you can afford 1 and 3 ct real diamond earrings? If not then they will appear totally unreal just by their size alone. And if you can afford real 1 and 3 ct diamond earrings then why are you at Overstock.com buying and reviewing cubic zirconium earrings?
My conclusion is that theses three pairs of earrings are totally worth the approximate $2.15 each per earring. I only wish that you could buy them as individual sets instead of having to buy all three pairs as a package, as my ideal set would be a 3mm, 4mm and 5mm ensemble.
