A super thumbnail! This specimen appears to be a complete floater and is composed of three, intergrown octahedrons of dark red cuprite, to 1.6 cm in length. Up close you can see a few spongy masses of native silver, to 4 mm in length, in association and for contrast. While there were many thumbnails, few are such nice and pristine clusters
