RM1712   Turquoise

Royston Mine, Royston, Nye Co., Nevada, United States

Curious specimen of turquoise, authentic turquoise, of a slightly greenish blue color, forming globular and elongated nucleus, in a matrix of goethite with other phosphates as possibly strengite. It is slightly polished which allows us to see perfectly the forms that the phosphate takes inside the matrix.


Size: 6.5 x 4.0 x 3.2 cm.

Col. J.M. Manchion (Barcelona)
