An excellent ring-sized stone with high level of polish and a brilliant lustrous, bright, visible inclusion of a rutle "starburst" inside the quartz. The rutile is nucleated around a hematite crystal at the core. Interestingly, these are now thought to be around 500 million years old (see attached note). Donated by Brian and Kendra Cook, Nature's Geometry Inc. specimen and photos. They own the mine that produced this gorgeous material, and operate in a village and community-friendly sustainable mining partnership, down in Brazil. See Brian's previous talk for the 2019 Symposium year, posted online at www.DallasSymposium.org.
