The Green “Jasper”, formed from silica-rich solutions depositing within pre-existing rocks, exhibits verdant hues due to iron impurities. During its formation, microscopic quartz crystals interlock, creating a dense, opaque structure. Variations in colour and pattern arise from differing concentrations and distributions of included minerals, such as iron oxides or hydroxides, which produce bands, spots, and other intriguing visual effects within the stone. | Omar Nacer
