100% Satisfied

I was nervous about buying a ring online but it seemed like it would be a wild goose chase trying to find an elongated hexagon moissanite engagement ring (which is what my now fiance wanted) so I took a chance with Brilliant Carats and I'm glad I did. The ring is high quality and the price can't be beat. I will be shopping with them again for a wedding band.
