[Picked from ETSY]
These beautiful gold stud earrings are made with solid 14K gold posts and clutches holding cubic zirconia with brilliant flash. The colors available are green, lavender, orange, pink, purple, and yellow. These stones are round brilliant cut stones, either 3 mm, 4 mm, or 5 mm. The stones are natural with no treatments.
Typically my photos are the 4 or 5 mm. Expect the 3 mm to be a bit less color saturated on the translucent gems. The smaller size gives less material to affect passing light.
The fourth photo is a general sizing photo for anyone unfamiliar with how much a 1 mm change can be for stones. You can find this item at http://www.etsy.com/listing/171581832/black-spinel-14k-gold-stud-earrings
