How can I tell the difference between and diamond and glass or even a rhinestone?

Answer 1

a true diamond will cut glass, run the diamond on a piece of glass if it cuts it is a diamond. God bless and Good luck, or take it to a jeweler.

Answer 2

OK if it is just glass or rhinestone that you are trying to differ from here is a simple test get a white piece of paper with small print on it take your stones one at a time and lay them across the small print if you can read any of the letters under the stone then most likely it is glass or rhinestone if it is diamond you cant read any letters.

Answer 3

If you want to be a really fancy git, you could try to get a piece of it off (good luck with that if its a diamond) and run it through a Mass Spectrometer to see if its pure carbon... or at least primarily carbon.

Chances are thats not an option though...
Like the others said... scratching is the key. Diamond is 10 on the Moh's Scale of Hardness... and can scratch just about anything (besides Ultrahard Fullerite). If you have a diamond you can have a lot of fun scratching lines into all kinds of other rocks with it... and actually cutting into them. You can grind it into metals too for that matter. If you try that with glass, then its the glass itself that'll get scratched. Check closely any such scratchline to see if its concave (inny) or convex (outy)...

And if all else fails... take a look at a few known glass windows and a few actual diamonds. They have different refractive indices... i.e. light shines through them at different angles and splits differently. Its hard to explain what each looks like... You just have to familiarise yourself with it firsthand.

Answer 4

For a simple, nondestructive, do-it-yourself test, just immerse it in Karo syrup. Ordinary glass will nearly disappear visually, since it is barely higher in refractive index. Diamond will still be quite easy to see and reflective, although less so than in air.

Rhinestones are tougher to predict, since they can be made of ordinary glass or leaded crystal, which is higher refractive index but still not as high as diamond. Best would be to do a comparison with diamond in the syrup.

If you put it in the syrup and it dissolves, then it was "none of the above" :)

Answer 5

Pick the gem and with it scratch a glass plate! If you succed you have a very high probability of it being a diamond! You can make a second test and calculate the refraction with a special equipment, or if you have a good eyesight, a very good lenses and mainly skill you can SEE the difference!

Answer 6

Lots of things will scratch glass besides a diamond. The best way is to check its SG ( density ) if it is a diamond its density should be around 3.5

Answer 7

test the diamond in the darkness a true diamond continues to shine a bit even in darkness. but a glass doesn't

Answer 8

Glass could have many compositions. a topic-loose practice was to easily make it out of melted sand, that's SiO2 (quartz). right this moment, although there are various extra ingredients to the silica to make it extra suitable and shatter resistant. Diamonds are certainly one of those carbon. They variety under intense warmth and stress deep in the crust. it is the toughest organic substance. once you're saying crystal, i anticipate you recommend something like Swarvoski crystal. it quite is comprehend as lead crystal and lead oxide has been added to regularly used glass to offer it an superior index of refraction so it is going to "sparkle" extra whilst faceted.

Answer 9

a diamond can cut or scratch a piece of glass or Rhine stone but they can't scratch a diamond.
a jeweler can tell by using a special gadget to measure it's
refractive index.
God bless,
gabe

Answer 10

scratch a peice of glass against a diamond, if it makes a mark, it is not a diamond, if it does not make a mark, it is not a diamond.
