I had been wanting a blue diamond ring for quite a while when I found this item on overstock.com. Never before had I found a .5 carat center stone blue diamond ring for this price. So, I decided to give it a try. The ring that originally came in had a small chip and scratch on the center stone that was not really visible to the naked eye; I found it with my jeweler's loop. So, I asked for a replacement to be sent. The second ring that came in had a very long and clearly visible scratch on the center stone. I decided to keep the first ring. It has a nice deep blue color, whereas the second ring had a deep teal colored center stone. Overall, I am happy with my new ring. The round clear diamonds are nice to the naked eye and the silver sparkles. This ring is not, in my opinion, an heirloom or engagement quality ring, but it makes me smile.
