Got a new little darling, I tried to take some photos, but I've never tried to take photos of something this small so pardon the fuzzies!
It's 4mm, I'd estimate H color.
Ebay, as usual, lol. I fell in love with the photo and just had to have it, and it's even more lovely in real life!
I started a thread on SMTB to get ideas. So far I'm leaning towards a etoile style ring.
