How to tell if diamonds are real?
I have 34 medium ish "diamonds" in a necklace and want to know if they're real.
a real diamond never breaks if u drop it (i think--it said in a comedy movie so i'm no so sure)
The absolute best way is take them into any jewelry store and ask if they will test them for you .. they have a special device that will measure the amount of carbon in the stones, if they are not diamonds it can tell.
Throw them on the ground if they don't break it's real
A real diamond can scratch a mirror
diamonds will cut glass...thats one good way to tell..
Reflection Color: Because of the refraction index of diamond, the reflection & sparkles in the stone should be shades of gray.MORE
