Rocky Mountain Gold!!!!     A fairly large Crystalline Gold specimen from the historic Sunnyside Mine, San Juan Co. Colorado.  Specimen has one diamond sawn face. Gold occurs as  granules, and irregular forms where Gold has crystallized around Quartz.  Gold shows brilliant luster, and a bronzy-yellow color.  Abundant Sphalerite in the matrix, with few % of Chalcopyrite and pyrite. . (untreated)

A Specific Gravity determination indicates 48 Grams Gold--However this is very questionable due to the abundant Sulfides.
