1 sand sample from around the world in labeled 10 ml corked glass bottles (about 0.6 - 0.7 oz of sand each).  Bottles measure about 2" tall x 0.75" wide.    The samples are all different -- very different!  Half of the samples come from North America, but some are from Africa, Asia, Europe, and South America too.  Most are ocean samples, but 7 are from deserts, as well as 1 lake and 1 river sample.  Some locations are familiar, but there are probably a few places you haven't heard of.  See list below.   Full set of ~24 samples -- $100.   All the information I have about the samples is listed below.  In a few cases, I just have a country name or region.  Sorry I don't have more specific info like the beach name, geo coordinates, or time of the sample collection.   Sand Sample Set:  Location Continent Type Antigua Africa Ocean Bir Lehlou, Western Sahara, Morocco Africa Desert Mauritania, Africa Africa Desert Nigeria Africa Ocean Playa De Ingles, Gran Canaria Isle Africa Ocean Tenerife, Canary Islands Africa Ocean Bahrain Asia Desert Hong Kong Asia Ocean Kuwait Asia Desert Kwajalein, Marshall Islands Asia Ocean Le Shima, Okinawa Japan Asia Ocean Okinawa, Japan Asia Ocean Oman Asia Ocean Rub’ Al Khali, Saudi Arabia Asia Desert Western Australia Asia Desert Baltic, Lithuania Europe Ocean Crete, Greece Europe Ocean Isle of Skye, Scotland Europe Ocean Nairn, Scotland Europe Ocean Oban, Scotland Europe Ocean Barbados, West Indies North America Ocean Block Island, Rhode Island, USA North America Ocean Cancun, Mexico North America Ocean Costa Rica North America Ocean Dominican Republic North America Ocean El Salvador North America Ocean Fort Lauderdale, Florida, USA North America Ocean Greenwich Point, Connecticut, USA North America Ocean Isla de Contradora, Panama North America Ocean Jamaica North America Ocean Kamaole Kihei, Maui Hawaii, USA North America Ocean Key West, Florida, USA North America Ocean Malibu, California, USA North America Ocean Mississippi Mud, New Orleans LA, USA North America River North Shore, Minnesota, USA North America Lake Pendleton, California, USA North America Ocean Puerto Escondido, Mexico North America Ocean St Croix, Virgin Islands North America Ocean St Pete Beach, Florida, USA North America Ocean St Thomas, Virgin Islands North America Ocean Yuma, Arizona, USA North America Desert Pacific Coast, Ecuador South America  Ocean Miami Beach, USA                            North America Ocean Sangalaki Island, Indonesia              Aisa                 Ocean
