This jasper variety forms in the Sonora region of northwestern Mexico, near the Arizona border. Volcanic and sedimentary processes created the mineral-rich deposits that produce its red and cream coloration.
Red Sonora Jasper rates 6.5 to 7 on the Mohs hardness scale, making it durable enough for regular wear in pendant jewelry without significant risk of scratching.
Iron oxide inclusions within the chalcedony create the red to burgundy tones. Cream and tan areas contain fewer iron deposits, while green streaks indicate the presence of copper minerals.
