by JPie » Jul 13, 2018 I've been a huge fan of Kataoka since I first discovered his jewelry in 2014. I collected a few things here and there, and thought I'd share some pics. Please post if you have any of his pieces! First up, the crown ring. 0.68 ctw of rose cut & brilliant cut diamonds, set in 18K yellow gold. Fun fact: there are two rose cuts in each station, stacked, to enhance the appearance of the top stone. Unfortunately, I can't seem to get this ring to look its best in photos.
