Polychromatic jasper is a recent discovery. It was found in Madagascar in the vicinity of an extinct volcano in the year 2006. It is a silicon dioxide ,thought to have been formed in the cooling phase of the volcano. The unique and various colours of the stone are due to the different mineral contents of the original sediments of ash thrown out by the volcano. This particular stone (38mm x 38mm) was cut and polished in our own workshop. The stone has a mysterious pastel forground in shades of cream , blues and mauves set off by a sienna brown background reminiscent of an old Japanese woodcut painting. Is that that a ghostly mountain rising up out of a choppy sea? The stone is simply set in a 5mm silver surround with an additional 1mm edging to complete the framing effect, and has two strong ¾ bails at the back in 2mm round wire, allowing for the free movement of the chain. CHAIN NOT INCLUDED. With this pendant we recommend the use, as displayed, one of our 16 inch silver Omega chain SCH03, with a sturdy and easy to use silver lobster claw fastener.
