i bought my engagement ring from bluenile and saved $6,000 over buying it in a store.
You can get F and IF (flawless and internally flawless) diamonds there, you cannot get that most places.
I had a secondary appraisal done on it locally and it came out higher than the one that was provided with the ring.
No point in buying your setting somewhere else, that just costs you more money. Or, send them your setting for the diamond.
They shipped it overnight to me for like nothing… very very very highly recommend.
