SPENCER OPAL
This is a piece of  rough opal from Spencer Idaho USA.It was deposited in volcanic rocks app 4 million years ago by geysers.When a geyser would erupt the liquid contaning tiny spheres of silica would form a  thin layer of precious opal.The opal colour bar is thin so it is ideal for cutting in to triplets.This field is known for its rare star patterned triplets.The opal  specimen has been glued to a stronger base for ease of handling.
This  rough can be kept as a specimen made in to a triplet or kept as a polished specimen.You can see some natural  fractures in the stone so it would have to be stabilized if you wanted a stone specimen.If so go to the FORUM on opal auction section then CUTTING OPALS then CUTTING /STABILIZING Ethiopian opals as it is the same for this type of stone.
