How I can know if I find a small piece of jade or not?

I found him walking on a beach in Costa Rica. It looks like jade and smells such as jade, after which I worked. Its dark green color with inclusions of lighter green, and this reflects its size is 3 / 4 "X1 / 2" X1 " and is almost as hard as an emerald.

A dark green stone with green spots .. hmm, could be jade. But it could be something else …. a quick trip to a jeweler or a gemologist is fixed? In fact, all you have to do is get a particular measurement of gravity on the issue (ie, a relationship between the amount of stone that weighed in the air against the water). Jadeite and nephrite is 3.33 is 2.95. However, there are some quick tests and observations that you can do at home that can explain to us what he has. Hold the stone in his hand. Does it feel cold to the touch? (You may have seen the Chinese and Burmese people in their cheeks touch jade to test your nerves as a sign of authenticity.) Observe the texture of the material. If there is a fracture, the texture should be hard and fibrous. If it shows fairly smooth and flat "defects" (Shear planes), you may have another type of green stone. example, Amazonite. If polished, it looks like a "dimpled" skin? Can you see the small veins the surface? If transparent, the material appears slightly fibrous? It's really hard to say what you have in your description. As a collector, I am pretty good at jade visual identification. If you have a photo, please send the URL to me and I will do my best to help!
