Hello Julie – At this time we do not have a 20″ snake chain. We do however have a 19″ snake chain. The price is $104.95 however we would like to pass a discount on to you so it would be $84.00 plus shipping and tax if you are in South Dakota. We do have 20″ in other designs I would be happy to show you. We do have a few other dome rings. If you would like I can take photos and e-mail them to you. Let me know what you think about the chain and if you would like to see more rings. Thank You-Debbie, Shankar Jewelry, 605-578-3808
