SCIENCE: CURRENT EVENT 6

What do you think of a gemstone such as ruby or emerald? Jewelery? Stones? Color? Well most people think of it as a precious gemstone (jewelery) that has beautiful colors. Scientist and others think of gemstones differently. It is hard to find the gemstone's origin by its weight or its color. It could be from Australia or Arkansas or it might have a identical one from the Democratic Republic of Congo. How you can figure out the origin of the gemstone is by the atoms and molecules that lie beneath the shiny colored surface. Scientists of Geological Society in Minneapolis found out that with enough information, we see which country it came from, the area of that country, and sometimes even the actual mine that it came from. Many of gemstones, including diamonds, comes from a war-torn country. It is because of the blood mineral that is left after a war. That is why governments say that these days, now that they can figure out which area the gemstone is from, people should sell the gemstones by the country the gemstone is from. When the scientists test the gemstone with the method of the atoms and molecules, almost 95% is correct. For rubies and emeralds, 98% is correctly from that country. But scientists have to test more gemstones before the method becomes a commercial use.

I think that it is cool on how scientist can tell the origin of a gemstone by looking at its atoms and molecules. Its also awesome son how science can tell everything and it can be used on everything.
