Chalcopyrite (Peacock Ore)
Copper Iron Sulfide (CuFeS2)
mineral
Blue Apatite
Ca5(PO4)3(F,Cl,OH)
mineral
Garnet (likely Almandine or a blend)
Garnet group: X3Y2(SiO4)3, where X can be Ca, Mg, Fe2+, Mn2+ and Y can be Al, Fe3+, Cr3+. Given the dark, somewhat reddish-brown appearance in the image, it's likely Almandine (Fe3Al2(SiO4)3) or a mix with other iron-rich garnets.
