Hi, snowmom, that's interesting and thanks for sharing. Read a bit on the webmineral and mindat website that reidite is "inclusions in shocked zircon grains with a scheelite-type structure..." Zircon is one of the prettiest gemstones, and thought you may find this interesting. "What are the oldest rocks on Earth, and how did they form? The material that holds the greatest insight into these fundamental questions, because it can contain a record of some of the earliest history of the Earth, is a mineral named zircon..." www.amnh.org/education/resources/rfl/web/essaybooks/earth/cs_zircon_chronolgy.html
