One of my favorite jewelry sets at Collabor88 is the Helen Jewelry Collection by LaGyo. It comes with a color changing hud and in silver and gold versions. You can choose from earrings, necklace, collier, headpiece and bangles. On the pic I'm showing the Helen collier and bangles in gold.
I'm wearing also the Faceted Solitaire Earrings and ring from Yummy, my dress is Lea from bava and my skin Izzie's Kaelyn 20's Skin (nude lips). All those items are to get at Collabor88.
