I'm not sure where to get a good price, but be careful when you clean it. These stones have a special coating on then that can come off with certain cleaners and ultrasonic cleaners as well.

I did some searches for you on ebay and you may be able to bid and get a good deal. i think you wanted it to be gold, so i put that as part of my search term. here's a link to the rings i found - some are really pretty! http://tinyurl.com i also found a few on amazon. i will link you to those, just click on the images and it will take you to the amazon page. good luck!
