I've decided to propose to my amazing girlfriend. I looked into he pintrest and talked to her best friend and found out which ring she as obsessed with.. problem is that it's apparently a Harry Winston ring which he is extremely expensive. I know she's the kind of girl that will be okay with anything but I really want to get her a ring like the one she's in love with. I was hoping someone knew of a look alike right or atleast some information on the stone (She's in love with the way the cushion stone looks and I know pretty much NOTHING about rings and stones -didn't even know it was called cushion till her friend said so-)
Please and Thank you
