How to tell if a diamond is REAL or FAKE using The Dot Test

[word]

The diamond's higher refractive index bends the red away from our eyes so we can't see it!

Not me thinking the fake one is prettier 😅

This only works with classical cuts though. Non-classical diamond cuts, such as a princess emerald or pillow cut will show the dot.

Hot take: the function of diamonds is to look pretty. If you can't tell a fake by looks it don't fucking matter if it's fake

[jackdog]

I stand by the fact that if you need to do weird tests like these to determine if a diamond is real, then there is no point in spending money on real diamonds.

High refractive index - 2.4 compared to for example glass as 1.5. The higher the index, the more light is bent.

I had an old school diamond that was worth a lot money. It belonged to to grandma. I had it appraised and the guy told me it was fake. Then he realized that the jewelry from 30’s and 40’s were cut differently.

I’d say if you need a test to determine if a diamond is real or fake. Just buy fake diamonds they’re cheaper, look the same to an untrained eye and they’re not mined by underpayed and overworked children in unsafe conditions

[BBAANNAANNAA]

Its because the real diamond is already covered in blood

Real Diamond lovers be like "The child labor makes it worth more 😊"

If you cut the cz properly it will be just like the Diamond (but more expensive for the better quality) white sapphire is better anyway

You can tell without the dot. The fake has a bluish tint to the light refraction the real one is pure white minus the facets of the stone.

If you can’t tell when you are wearing it then buy the cheap one😂😂😂😂

[sydkoy]

The real one is low quality tho, you can see the clarity and color aren’t the best. 2 of the 4 c’s aren’t properly met here for a higher quality Diamond.

I kinda like it being see through though.

[JonGardner]

Cracks me up that cubic zirconia are considered "fake" only because the fiat value of natural diamonds is artificially (and arbitrarily) inflated.

[MsClrs]

It would totally depend on the diamond cut right?

[RRALPHYY]

Doesn’t the way the gem is cut affect the way the light bends which shows the dot?

[prachijain]

The fact that I understood the reason immediately, my physics classes paid off haha! We did discuss about diamonds in optics so that knowledge came handy!

[ObservingAllThereIs]

If it's hard to determine which one is real, why would you even want a real one?
They're just worthless shiny rocks.
