How do I know if I found a diamond?

Question

this rock is trasparent and looks like class it cuts class

Answer 1

take it to a geologist or a diamond cutter

Answer 2

Take the rock you think is a diamond. Find a copy of Mohs scale:

If it will scratch glass, and glass will not scratch it then pull out a hardened steel file. If you can scratch the file without the rock scratching with a file, then you have reason to go to a gem show, ask a dealer and they will normally help you do a final identification.

Hey MrMike, this is a follow-up to your other question. Thanks for selecting my answer as the best answer, but in your comment on my answer I finally understood your question. The other answerer and me both thought that you were asking about a particle-wave duality, a quantum phenomenon that only really occurs on an atomic scale. In your comment I understood you were actually asking about a different phenomenon, so I wanted to answer that.

You were basically asking about sound waves. If you match powerful enough sound waves to the "frequency" of an object, you can destroy it, as every cartoon where somebody sings in a high pitch and a window breaks demonstrates. It's a bit harder in practice, but just as for electromagnetic energy you have the equation (speed of light) = (wavelength) * (frequency), it is also true that (speed of sound) = (wavelength) * (frequency). Once you know the speed of sound in the material (it's ~300m/s in air, ~1500 m/s in liquid and ~5000 m/s in solids), and the "wavelength"--i.e. the size of the cancer cell--you can calculate the necessary frequency. Then if you hit the cancer cell with that frequency you will break it up. Unfortunately, the rest of the cells in your body are the same size, so they will break up too. But in a laboratory people use this technique very commonly to break up cells so you can isolate things from them. It's called sonication, and you can read a bit more about in this short wikipedia article http://en.wikipedia.org/wiki/Sonication but if you really want to learn more about it just google "sonication"

Good luck. In the future, the more information you put in when you ask the question the more likely answerers are to give you a better answer...

Answer 4

the refractive index of diamond is very low thats why if a light ray enters into it, it suffers total internal reflection and thats why diamond glows in night. Actually very few rays goes into it and suffers total internal reflection and it begins to glow.So if u find a diamond, place it in adark rom and pass a tiny ray.If it begins to glow then u r lucky one.

Answer 5

If it cuts glass then its a diamond

Answer 6

Put water on it, diamond repels water like grease or oil. You can't wet it, it looks really soapy.
