Hubei turquoise, from Hubei Province, China.
Standard-High grade, stabilized and unbacked, ready for a silversmith to set.

A clean oval of sky blue that settles through its lower third into a soft seafoam green, the two meeting without a line. Fine black matrix threads across the upper end only; the rest is clear, with one small brown fleck at the lower left edge. The polish is bright, the dome low and even. The back is flat and unpolished.
