MÁLAGA / Spinel

Local collectors found Spinel on Dolomite matrix. The crystal form is not excellent, but their color is not bad and the contrast with the white matrix is good. Plus they are fluorescent (red). Some minor yellow Clinohumite crystals are also present, these are fluorescent too, in this case yellow.

NE10R7: This Spinel comes from the first discovery in the Mijas area of this species, which is quite rare in Spain. It is characterized by its color, distinct from other Spinels from this area, as well as its good crystal definition.
As a plus, we can give the precise name of the place where it was found (El Chambao)

It is transparent and bright and has attractive inclusions of hydrocarbons and the beginning of “windows” on some of its terminal faces. We call attention on the position of the crystal on the matrix that enhances the esthetics of the specimen as well as increases its value because specimens of Quartz with matrix are pretty unusual in Berbes.
