My husband and I spent 2 weeks on researching hoping to find a "perfect" stone. At last, we ordered the ring from BN. It arrived last Friday.Initially it was a great pleasure because this one is very bright. But later on we figured out it doesn't have a lot fire... Now hesitating if we should return it and get another one... Here's the link to the stone: http://www.bluenile.com/diamond-details/LD04923850
We used the HCA calculator and this one is 0.7.
Really need your advice here! Is there a way that we could tell the diamond has great fire statistically? Should I return this one? Any opinion will be so much appreciated! Thank you!
