"I purchased a center stone for an engagement ring from McGivern Diamonds. The stone was delivered overnight and was exactly as Michael described on the phone (beautiful). I had called Michael with a handful of diamonds and wanted a recommendation - he called me back 30 minutes earlier than promised with a recommendation and walked me through his thought process.
I took it to a local jeweler who was very impressed with it. He also told me that the price I paid was about what he would've paid for a similar stone.
My only regret is that I didn't find their website sooner - my search would have been a lot easier."
