• Minerals : Spinel on calcite matrix and forsterite
    Dimensions : (8.91×7.81) mm pour for the biggest crystal and (46.73×41.39×26.92) mm for matrix
    Weight : 64g
    Treatment : None
    Origin : Parker mine, Notre-Dame-du-Laus, Québec
    Information : Because its marble (calcite and dolomite), quartzite, amphibolite, and pyroxenite formation, Parker deposit provides formation such as this matrix that consists of calcite, forsterite (the greenish formation on matrix) and black spinels.

  • Minerals : Spinel on calcite matrix and forsterite
    Dimensions : (4.11×3.99) mm for the crystal on the tip and (53.62×57.46×36.92) mm for matrix

  • Minerals : Spinel on calcite matrix and forsterite
    Dimensions : (16.75×13.74×17.29) mm for the crystal and (21.72×16.59×17.23) mm for matrix
    Weight : 6g
    Treatment : The matrix was placed in hydrochloric acid to remove the calcite excess.
    Origin : Parker mine, Notre-Dame-du-Laus, Québec
    Information :
    The use of HCl on this matrix had the effect of removing all the calcite without altering the integrity of the spinel crystal. However, forsterite has been altered in the process rendering it brittle on its surface and removing a little of its greenish complexion.

    Origin : Parker mine, Notre-Dame-du-Laus, Québec
    Information :
    The matrix has a structure of forsterite crystals yellowish rust type. This structure does not have any predominant crystal spinel, but a multitude of spinels through crystals of forsterite.
