I really like the way this specimen sits up unaided and shows off two spinel twinned galena crystals to 3cm each sit on a matrix of smaller untwinned galena crystals, quartz, and sphalerite. The galena displays a mirror bright luster so reflective you can see the photographer's face in the crystals from a foot away! The crystals exhibit a silvery-gray color that is more attractive in person than it seems here, as well.
