Beautiful Earrings
Size: 1.25 Carats, Color: 14k Yellow Gold
These are absolutely gorgeous. So sparkly. Bought a pair for my son's girlfriend. She doesn't take them off. Ended up getting pairs in various sizes for her mom and myself as well.

Gorgeous 1 ctw lab created diamonds
Size: 0.20 Carats, Color: 14k White Gold
These 1 ctw lab created diamond stud earrings (1/2 c per ear) are as beautiful as the real deal! The color is white and they sparkle like crazy when you glance in the mirror. The size is exactly perfect for me, not too outrageous and not too invisible. I bought these as a present to myself with my Amazon credit card reward dollars!
