Truly beyond my expectations

My ring is a custom size elongated radiant solitaire (11x8) with an hidden halo and she is a stunner. I just got engaged and already am receiving so many compliments on my ring. The craftsmanship is exceptional and I love how they cut the radiant stone. My fiancé said that it also was made and arrived quickly. 10/10 and can’t wait to get my wedding band from here as well!
