Hey bees! just for fun-recently moved house and when having a clear out I came across this stone I found years and years ago in the street (like 11 years old!).other than going to the jewellers-does anyone know of any tests which I could do to see if the stone is a piece of glass or a jewel? Honestly think it is worthless but was just pondering as I remember years ago round about valentines day jewellers were offering to test diamonds for free to see if recently engaged people’s diamonds were real!

Hold it close to your mouth and scream loudly at it for 30 seconds. If it fogs up and stays that way for more than a couple of seconds, probably not a diamond.

Jabberwocky: thank you.will try this when I get home from work-have a feeling a 30 second scream will do me the world of good also!

Haha Jaberwocky I love the scream test idea! But VioletV here’s some other ones to try without the neighbours calling the cops http://www.wikihow.com/Tell-if-a-Diamond-is-Real I always thought it was something about scratching glass with a diamond?

Diamonds are great heat conductors. Put the gem on a surface and then let it get to an ambient temperature (the same temperature as the room). Then lean over it and without picking it up touch it with your lower lip. A diamond should feel cold.
This isn’t a conclusive test – you need a gemologist for that – but it’s a good indicator.
You use your lip because this is much more sensitive to changes in temperature than your hands

Diamond test are always free that was just a scam to get people in on for VDay. Every jeweler (even chain mall stores) will have the hand held diamond tester. And it will be free for it to be Tested.
1) breath on the diamond is a good one (no screaming needed lol) Bassically if you breathe on it to get it to fog by time you stop and pull it away from your mouth you should have just time to see the stone fogging up before it goes away
2) turn it upside down on a paper with type all over it. A diamond will not show the type but a CZ/white sapphire ect will.
3) go to a jeweler. haha

NEAM2014: I tried this with my moissanite because I was curious. It fogged up of course when I did the breath test but when I tried to look at text, I couldn’t see through it. I wonder if it’s just because moissanite is “kinda” diamond like? I can’t figure it out…know anything about that?!
