This YSL ring. I haven't seen it irl, however everytime I have seen it being worn in photos it looks amazing. Almost looks alien-esque when not on a finger.
I also think the colour is amazing, and would look great in summer.YSL ring $295 (buy online from cult status)

Don't know if I should risk ordering it online. Firstly don't know my size, secondly don't know if I will like it on me.

I also have been eyeing these beauties since they were created.Buy on cult status $1295
