HOW TO TELL IF SAPPHIRE IS FAKE?!

Not helping ur video

So you didn't even show the displacement of water... how did you do that with such a small stone?
worthless video

How can you easily tell if this sapphire is real or fake….

Means it's real

So if I scratch a sapphire with sapphire it will scragch

Ty so much

Please translate your program to Arabic languages to be more useful, thanks , f .

So long as neither you or anyone else who might be trying to sell the stone aren't claiming that the stone is natural, as long as the density, appearence, and hardness are the same why would it matter?

Hello and thank you for your video, very interresting!
Would you mind explaining how could I calculate myself the volume of some gems to determine the density, I know the process of using diff of water (emmerging) but I don't know any tool that can be such precise to get this value properly ?
Any advice ?
Thanks!

When working with gems a white or black background makes it easier for others to see the gems as well as good lighting. Thanks for your info!

Very useful video. Do more testing videos Ali as they truly demonstrate the art of gemology.

Be careful useing the machine that you asked if the math was right because it can hear what you are saying when you think it's off. They had a story about it on TV.
I just got a beautiful yellow/gold single stone sapphire from China. Of course I don't know if it is 'real' or not, esp. After seeing this video. Maybe I should send it to an outside Gem place.
I hope it is real but I only paid $16. for it & $6. for shipping. It's way prettier than the picture so I wonder if someone sent me the wrong stone. Even if it may turn out to not be real it still will make a nice ring. It's nice to come here & learn from a knowledgeable teacher like you.

Thank you! I cannot wait for the emerald one, as I frequently purchase stones to make jewelry and have struggled for years with being ripped off! The integrity of the pieces that I make mean EVERYTHING to me, as it is my intention to give my customers the best possible product for the least amount of money. I have had to raise my prices due to constantly being ripped off, in addition to having to pay to have many stones tested before I can use them.

.... Very interesting , Mohamed !
Thank you for all of it !!
CHEERS !!!
