This is a delicate Ocean Jasper pendant. It comes with the copper bail and the brown 'leatherette' necklace.
Ocean Jasper is a variety of Jasper which contains variably-colored orbs or spherical inclusions or zones. This material is quite attractive when polished and is used as an ornamental stone or gemstone. The name "Ocean Jasper" is used for the variety of Jasper found along the intertidal shores of northeast Madagascar.
Jasper is a form of chalcedony quartz, and is opaque rather than clear or translucent like regular quartz or agate. It contains an abundance of impurities which give its interesting appearance.
There are over 3,000 types of agates and jaspers, and this is a nice representative of one of them!
(As always, if you don't like the choice of bail or necklace, just contact me and we can make changes.)
