    "What a gorgeous Native Gold ! 
    It's completely crystalline with flattened dendritic crystal growth to 
    the right and dodecahedrons and trigons crystals to the left. 
    When the specimen was forming, a small seam probably opened up in the Quartz matrix and allowed for the development of larger, unflattened crystals. on both the front and back side of the specimen. The flattened crystalline growth to the right is pure dendritic, displaying beautiful herringbone patterns throughout. 
    From the Eagle's Nest Mine, Placer County, California. 
    Measures 6.1 cm by 6.7 cm in size."

    "A superb glassy gem quality transparent fluorite crystal measuring 1.7 x 1.6 x 1.6 cm is attractively studded on the side of a 4.6 x 3.5 x 2.5 cm matrix. A tiny chip is present on one crystal edge, seen only by my eyes with magnification. For one of these, this is in excellent condition. The quality is exceptionally high for a Fort Wayne fluorite miniature. Collected in the early 1970's."
