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!
