Dioptase with Calcite Gemstone Carvings spindle-shaped fossils have surfaces marked

spindle-shaped fossils have surfaces marked by weak spiral lines in a helix

commonly schist

They are considered to be “living fossils” because of the great similarity between modern and fossil forms

Although most hair remains are orange in color

Quartz occurs in crystalline masses

Dioptase with Calcite Gemstone Carvings spindle-shaped fossils have surfaces markedDioptase crystals are emerald green and translucent. The mineral got its name from the Greek words for "to see" and "through" because of the ability to see internal cleavage planes of the small crystals. The mineral forms in rhombohedral crystals (usually less than 1cm in size) with a chemical composition of CuSiO3 (H2O).
