My avatar has been hogging these beautiful eye diamonds for too long!
Now every girl can wear these diamond jewels which add elegance in close ups
and highlights from far away views!
These can be worn with any skin. Try to avoid hairstyles that are opacity mapped, and so far they look best on the default head, ellen head, bobblehead, lifeless head.. typically on other ones (jen head and head 4) they appear as one diamond outside of the eye.

Very easy to derive! You only need one texture of any size, just experiment and play!
