    PARAIBA TOURMALINE

    Very Fine Gemstone: Cuprian Tourmaline (Paraiba Type) - 51.07 Ct.
    Alto Ligonha District, Zambezia Province, Mozambique

    After Paraiba Tourmaline was first discovered in Paraiba, Brazil, demand skyrocketed for these intensely colored gemstones, and the original locality was quickly exhausted. It was noted that a few Tourmaline localities in Africa hosted the same copper-bearing type of material as the original Brazilian source. As a result, the category of "Paraiba Type" Tourmaline was officially instituted by trade organizations in order to clearly define this special type of Tourmaline. Light greenish-blue in color, this fancy cut trillion hails from the gem rich Alto Ligonha region of Mozambique, where small-scale mining operations occasionally result in a 'strike' of gem crystals. Only rarely are the crystals large enough and "clean" enough to furnish eye clean gems the size of this one. At 51.07 cts. this scintillating gem comes with AGL Cert # CS 65931 which gives dimensional data and states they believe it to be from Mozambique and that its clarity has not been enhanced. This is a truly 'eye catching' gemstone.
    Measurements: 26.56 x 23.55 x 15.67 mm, 51.07 cts.
    Offered at no reserve.

    Provenance: Rainbow of Africa Collection
    Accompanied by AGL Certificate # CS 65931
