For thousands of years meteorites have slammed into the earth's surface, each one carrying an invaluable record of the very beginnings of the solar system. But finding meteorites -- some buried over centuries by thick layers of dirt and sediment -- is no easy task. Modern day treasure hunters Steve Arnold & Geoff Notkin have travelled the world for years to search for the remnants of these ancient meteorites. The Meteorite Men series on the Science Channel takes viewers on a search for alien treasures & reveal these lost treasures of the universe. For its pilot series in 2008, the Whitecourt Crater, in Whitecourt, Alberta, was the only location outside of the US. Since then, the series has taken off and the Meteorite Men have hunted for meteorites around the world. And, in August 2011 it took them back to the Whitecourt Crater where they met avid meteorite hunters Luc and Joan Guillemette.

Gold was the first metal widely known to our species. When thinking about the historical progress of technology, we consider the development of iron and copper-working as the greatest contributions to our species' economic and cultural progress - but gold came first. Gold is the easiest of the metals to work. It occurs in a virtually pure and workable state, whereas most other metals tend to be found in ore-bodies that pose some difficulty in smelting. Gold's early uses were no doubt ornamental, and its brilliance and permanence (it neither corrodes nor tarnishes) linked it to deities and royalty in early civilizations .

We do know that February has long been celebrated as a month of romance, and that St. Valentine's Day, as we know it today, contains vestiges of both Christian and ancient Roman tradition. But who was Saint Valentine, and how did he become associated with this ancient rite?

Pearls are very soft and need special care. They never should be tossed on top of or next to other gems in a jewelry box. Store them in a jewelry pouch. If a pearl necklace is regularly worn, as it should be, some of the pearls will constantly be in close contact with the woman's skin on her neck at the shoulder line. Pearl pendants do not always have such constant contact with a woman's skin. The pearls in the necklace will gradually absorb acid from the skin and the acid will slowly eat into the spherical pearl. Over time the pearl will not only lose its luster, but will become barrel-shaped. You can slow this process by wiping the pearls with a soft cloth after wearing them.
