_small.jpg) | Lustrous undamaged Hematite crystals with reddish brown Andratite. Not photographed is the back which has crystals that are white hexagonal prisms which seem to be Ettringite which is usually light yellow to yellow but mindat also has photos of white Ettringite. Calcite and Barite are eliminated because of the crystal shape which is what I thought it originally was and did not photo them. ex Glen Davidson colleciton. |
