This is a gorgeous hand cut swamp bog jasper and probably one of my top 3 favorites. This stone has a lovely green blue hue.
It owes its color to the trace elements present in the swamp bog that eventually was turned to jasper.
It's cut into a long triangular freeform with set in a heavy gage split shank ring design.
The ring is a size 7 and can be sized from a 6 to a 9.
PLEASE CONTACT ME ABOVE WITH YOUR FINGER SIZE.
The stone used here measures 30 by 14 mm or about 1 1/4 by just over 1/2 inch wide.
Jasper is an opaque form of Chalcedony, which is a microcrystalline variety of the mineral Quartz. It often contains an abundance of impurities, and therefore some regard it as a rock instead of a mineral. Jasper is usually associated with brown, yellow, or reddish colors, but may be used to describe other opaque colors of Chalcedony such as dark or mottled green and orange. Some forms of Jasper are banded, and these banded Jaspers may appear similar to Agate, but unlike Agate they are opaque. When Jasper is dull and lacking interesting colors or patterns, it is not Jasper but rather Chert. - See more at: http://www.minerals.net/mineral/jasper.aspx#sthash.KsFIRXyW.dpuf
