Description
A gemmy thumbnail sized specimen of soft orange color â??Blood Vessel Opalâ? with good quality glassy â??beadâ?-like globules free of matrix. A bit of rough edges here and there keeps it from being perfect, hence the reduced price. There is also a bit of secondary white opaque Opal overgrowth, which gives it character, but do not mistake it for damage or being dirty.
