One-of-a-kind natural apatite on calcite. You will receive a piece similar to those shown. Size: 5 to 6 inches (sizes vary) Apatite is a phosphate mineral that commonly forms in igneous and metamorphic environments, while calcite is a calcium carbonate mineral typically formed in sedimentary settings. This combination occurs when apatite crystals grow within or on calcite during overlapping geological processes. The blue to green color of apatite is caused by trace elements such as iron and rare earth elements, while calcite is usually white or pale due to its composition. These specimens typically show prismatic apatite crystals contrasting against a softer calcite matrix, often mounted on a metal stand to display the natural structure. Each item is unique in shape, color, and pattern. Higher-grade pieces are selected first. Photos represent overall quality and appearance.
