Beautiful 1.5ct Cushion Asha Solitaire

I have a stunning sz 7.5 (can be resized) stunning 1.5ct cushion cut Asha solitaire. Set in white gold. The ring is beautiful, although it could stand to be re-dipped for additional shininess on the white gold. 


I am in the market for something larger now. I paid $500 for it from AshaDiamonds in 2013, and have original paperwork.
