I must brag.
My wife had a 1.75ct ring from her family, so I knew I was screwed. I bought a 1.75ct on eBay for $1000 from the guy in Beverly Hills who sells rolies since he seemed trustworthy (Beckertime I believe). Another $500 locally for a mount with two small diamonds on either side. Perfect color but heavy on the inclusions. However, they are all white so other than a slight loss of brilliance it looks exceptional to the naked eye.
The gals go nuts over this thing, much to my satisfaction.
