Spotting genuine chrysocolla involves a keen eye. First off, examine its color; true chrysocolla boasts a unique range of blue-green shades. Next, check for a glassy to dull luster, which is a hallmark of the mineral. Lastly, consider its association with other minerals like quartz or malachite, as chrysocolla often occurs alongside them. When in doubt, seeking advice from a reputable gemologist can help ensure authenticity.
