This is a large, heavy specimen of pegmatite matrix. Euxenite is really the main mineral and occurs within the specimen as large crystal grains from 5mm to 18mm. They are dark brown with an vitreous luster. The Xenotime grains are 4-18mm and are kind of a yellowish brown replacing the Euxenite. The specimen originated from the Paul Moore collection with tag, though his name does not appear on the label.
Because of the size, the specimen may cost extra to ship beyond the cart charge if shipped outside of the USA.
