Making this ring was quite an adventure! I have never had to individually fracture, shape, and adhere material to make a continuous inlay before. This mammoth ivory was unearthed in Texas, where mammoths resided between 10,000 and 1 million years ago. Unlike other mammoth ivory I have used, this material is much closer to stone than horn. This means it is much too friable to form a continuous ring. I decided to inlay it into my own matrix mixture- a super fine black stone from Sri Lanka and epoxy resin.
