Jamming Gems is a Family Owned USA based company that has been supplying the gemstone and jewelry trade since 1991. We began with a love of gemstones. Our owner began collecting and cutting opals. As the collection grew so did our passion for the industry. We began expanding into other areas of the industry and exhibiting at trade shows across the country. Originally located in Southern California, we exhibited at many major trade shows along the west coast and made appearances all the way to Massachusetts. During our time exhibiting at trade shows we showed at International Gem and Jewelry Shows, Gem Faire, and the Tuscon Gem and Jewelry Exchange Wholesale Show.
We began selling on eBay in 1997 as one of the first and only gemstone/jewelry sellers. Seeing the opportunity to provide to our customers over the internet we created our original website. We now have two generations working together to serve your gemstone and mounting needs.

We offer many products and services including casting, gemstone cutting, jewelry manufacturing, gemstone setting and ring sizing at very competitive pricing. Please read about our casting process to learn more about how we strive to provide great products to you!
