This ring design is a commission from a friend of mine who is a tailless whip scorpion (AKA Amblypygid) enthusiast and breeder. It probably looks very alien if you've never seen one of these critters but they are extremely cool. I created a model of one a couple years ago which gave me a nice head start on this ring design (see last two images). So the request was to make a ring to celebrate the 2nd wedding anniversary of her and her husband. She is the whip scorpion enthusiast and he is an astronomer so the back of the ring has the four Galilean moons of Jupiter featured. The pair of rings were cast in gold by Rio Grande and treated by Tony Rodriguez to bring out the details (I'm not sure the method he used but he says its pretty old-school).
