From the historic mines of La Trinidad in Querétaro, Mexico — where rhyolite lava flows once hosted rich gas-cavity opalization — this specimen comes from a region known for its distinctive “cantera” style opals, with vibrant color living directly within the host rock. Small-scale mining in the area dates back over a century, lending this piece both geological and cultural provenance
