While true gem opals are found a thousand miles from North Texas, our local prairies are home to “living opals” hidden within the iridescent exoskeletons of beetles. By mimicking the same light-shifting physics found in precious stones, these insects use microscopic layers of chitin to create stunning displays of structural color and metallic luster. Join Randy as he explores the intersection of mineralogy and entomology, sharing photography tips and the “collector’s code” for finding these shimmering natural wonders in our own backyard.
