This is an Ocean Jasper Palmstone from Madagascar. Ocean Jasper is a particular variety of orbicular jasper that only comes from Madagascar. It was named Ocean Jasper because the original mine was so close to the ocean that it could only be mined from at low tide. This piece features a deep green color with bright white lines and circles primarily on one side, but a few scattered throughout the whole piece.
This piece measures approximately 7.3cm x 6.2cm x 2.9cm
