Background
CD52 is a GPI-anchored protein present in lymphocytes and male reproductive tissues (mrt) including mature sperm and seminal plasma. It has been shown that mrt-CD52 is synthesized in epithelial cells of the epididymis and vas deferens, but not in the testis. The mrt-CD52 is transported to mature sperm during sperm transition in the male reproductive tract. Lymphocyte CD52 functions to stimulate suppressor T cell induction, while mrt-CD52 is associated with seminogelin and involved in clot formation and liquefaction of semen.

You can wear them in the water because they are 14 k gold
Love these earrings. They were a little smaller than I thought and the clasp gets wonky after a while.

These have been a conversational piece
Style: 16mm Rose Gold
I thought these were cute. I purchased two sets because I have two holes. They seem like a good quality of rose gold. They are not to big but the heart just hugs my ears.

Deceiving measurements
The earrings are pretty. However, the description shows 2 mm thickness and mine are 1mm (barely). The picture also shows measurements from 16-20 mm which is hard to judge. Mine are 16mm (that’s okay).
Lastly but not least, I found the exact same earrings for half the price so now I feel like I over paid for these ones.

Highly deceptive on size, and the packaging is trashy!
Style: 20mm Yellow Gold
A coworker and I purchased these earrings as a gift for another coworker. They arrived today thrown in a plastic bag, with a cheap box that says "LooptyHoops" along with fliers about their other jewelry! The earrings are not ANYWHERE near the size we ordered! I am questioning the legitimacy of this company, and if their earrings are 14K gold!
