Sourced from the Clear Creek Management Area in San Benito County, California, this agate forms in altered serpentine and volcanic rock, creating its signature mix of translucent glow, mossy inclusions, and swirling patterns. Colors range from greens and teals to creams, golds, browns, and smoky translucence. With a hardness of ~6.5–7, it’s durable and ideal for cabochons. Collecting access in the area is restricted, making well-patterned pieces limited and highly desirable.
