They repaired an opal ring for me. Did a great job.

Grace is A+mazing! She is one of the most genuine people I've met and has great communication & customer service skills. She's honest, trustworthy & will not take advantage of you like many of the companies in the jewelry industry. She takes her time with you to find out what you really have in mind and then some! I only trust her advice and care of my jewelry now. For future quality purchases Gem Garden is where I will go! Thank you Grace! :D

This review is very late... however, my experience with Gem Garden was excellent! My 12 year old son visited the Gemological Institute of America on a school field trip and came home with a small stone that he wanted to make into a ring for his mother for Christmas. The owners went above and beyond the scope of their work to help him find a ring to mount the stone. After much searching there was no ring available to fit the stone. The owners created wonderful sterling silver pennant that went on a chain as a necklace. The work was outstanding and my son was so proud and could not wait to give it to his mom. Moreover, the owners packaged an emerald apple for my 8 year old son to give to his mother so he would not be empty handed. They are a class act and wonderful to work with. If you are into gems and stones this is the place. Additionally, they have many other little great gift ideas. Go check it out, a cool little place with tremendous owners.

I needed some help with a ring I found while cleaning out old stuff. These people were so gracious and knowledgeable. I much appreciated dealing with them and will do so if I ever need their services again in the future.
