Bermuda Sand Grains
Sand grains from the beaches of tropical islands like Bermuda are filled with fascinating remnants of biological organisms, including sea urchin spines, shell fragments, bits of coral, glass-like sponge spicules, and the tiny shells of single-cell protists known as forams.

Maui Red
Three sand grains from the red sand beach at Makena Point, Maui are heavily eroded, revealing their beautiful interiors.

Puffy Stars
Star-Shaped Sand Grains from Okinawa. These tiny foram, a type of protozoa, secrete beautiful star-shaped, calcium carbonate shells, or tests.

Heart Gems
Sand grains from around the world are mixed together like a pouch full of gems. The sand grains are from Maui, Hawaii, Japan, California, Ireland, Bermuda, and Minnesota.

Blue, Orange & Pink Sand Grains
The tip of a spiral shell has broken off and become a grain of sand. After being repeatedly tumbled by action of the surf this spiral sand grain has become opalescent in character. It is surrounded by bits of coral, shell, and volcanic material.
