Blue Onyx, often known as Banded Calcite, is a captivating stone composed primarily of calcite and other carbonate minerals, though it is not a true onyx. This beautiful crystal is typically found in regions such as Mexico and the southwestern United States, where its vibrant blue bands form over many years. Discovered in the early 20th century, Blue Onyx is valued for its believed calming energy and grounding properties.
