Aventurine (orange)

Orange aventurine is an orange colour variety of aventurine, a natural quartzite or quartz rock whose small platy inclusions can make it glitter (aventurescence); the iron oxides hematite and goethite produce orange to red and brown tones. The Japanese retailer Pascle says its orange aventurine shows little aventurescence and is sometimes called orange quartzite. It is a natural rock, not goldstone glass and not sunstone feldspar.
