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.
