Sand grains magnified 110-250 times — tips of spiral shells, bits of coral, shell fragments, protozoa, volcanic material, calcium carbonate shells, biogenic sundries, fragments of baby sea urchin shells and tiny crystals from Maui, Lake Winnibigoshish, Okinawa, Zushi Beach and the Virgin Islands. Thank you, nature.
