All of these rings feature our Maine gemstones! Many of these are "one-of's"; designs you won't see again. If there is no size options, sizing is included in purchase. Please let us know what size is needed and we will size it for you. Looking for that special ring to ask a certain question with or are you looking for a custom designed for you ring, please contact us! We have loose gemstones available and will be happy to consult with you.
