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

the distinctive pattern of the six-sided coral fossil emerges

Within the "Gemstone community" Zircon is not a commonly used stone

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

Dioptase with Calcite Gemstone Carvings Although most hair remains areDioptase 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).
