Calumet Mine, Turret District, Chaffee County
6.8 x 5.2 3.3 CM (cabinet)
A plate of Epidote that shows two different colors and has a few bi-color crystals. In very good condition the crystals reach up to 1.5 CM though most are smaller. Most crystals have gemmy faces, are transparent and have a yellow to dark green color range. From the old Calumet Iron mine in Chaffee County Colorado, this is above average for size and quality of the crystals on matrix. Many of the crystals are well striated with very sharp and distinct forms.
A very well-documented and fine Colorado classic piece, this comes with 5 old labels, one of which notes: Collected in 1946 by C.G. Coil. Clarence Coil was a significant figure in Colorado Mineralogy. Well-formed, terminated crystals are on several sides and in one large vug. This was in many collections over the years, including Elberto Tealdi (Milan, Italy) and Richard Kosnar. The esthetics and satiny luster in person show why it was included in these fine collections.
