Gaspéite is just a mineral that is rare belongs to the Calcite team of minerals that includes Calcite, Cobaltocalcite, Magnesite, Rhodochrosite, Siderite, Smithsonite and Spherocobaltite. Gaspéite is being used in the precious jewelry trade for beads, cabochons, pendants and carvings. Gaspeite is most illustrious for its apple green color, however, its color will vary from pale green to bright green. Most can exhibit brown veins.
