Blue Sandstone is achieved by substituting cobalt for copper. The resulting crystals have a more silvery appearance and are suspended in a strongly colored matrix of the corresponding ionic color, resulting in blue goldstone.
Blue sandstone is considered to have calming properties, helping to alleviate stress, anxiety, and restlessness. It promotes a sense of inner peace and tranquility, allowing the wearer to maintain a balanced state of mind and emotional well-being.
