from my personal estate of jewelery :) as seen on me in many of my videos over the years! solid 14kt white gold, real (not lab! natural!) sapphire & real (not lab! natural!!) diamonds. absolutely fabulous. currently a size 6.5, but any local jeweler could size for you 💕 i bought this from a jewelry store but as added security posh authenticates orders over $500, so the ring will be tested for authenticity for you prior to arrival 💕 One of my favorites, hope you love it XOXOX
