I lost the solitaire diamond from my engagement ring...LUCKILY I found it in my purse! Dan came to the rescue and recommended a stronger mount, checked all the stones in both my engagement and wedding rings, found another mount that was about to lose a stone, and was the kindest, most helpful person....and he and his expert jeweler did it all the same day for me so I wouldn't have to be without my rings. Great quality, great customer service - thank you so much Dan!
