Well, My teacher only told us about this technique just only for Tsvorite garnet. Its additional knowledge I got that many of stones which have Iron in it can be tested by this method. Thanx a lot for uploading such a worthy knowledgeable video.
Thanks for demonstration. It is indeed a new concept in identification of gems from natural to synthetic and pretty easy to do as well as easy on one's pocket! 👍
I think to assign a value to the measurement you'll need a commonly agreed (international standard) magnet so the same force is applied with any of these standardized magnets. Then of course you'll need to standardize a way of determining the force of the attraction. For example (and I don't think this will be the best way) using your water bowl and float you coud measure the speed of the movement by using the elapsed time for moving a given distance with the magnet resting at a fixed distance from the starting location. You'll need a standardized styrofoam float (raft), distilled water, a distance scale, and a stopwatch. I know this would not be the best way to do it, but I think it could work somewhat. Tyhe biggest problem is having specimens to measure that are also a standard siza AND shape. Maybe they could make a gradiated accurate magnetic field viewing film? (Look it up if you haven't heard of this film. It's just a translucent sheet you hold over the magnetic object to view its magnetic field. Neat-O!) And that's my three cents!
Excellent points and right on the money. After this video, there were scientists involved who developed a system of measurement. Kirk Feral developed a website with a lot of great information: www.gemstonemagnetism.com/.
I think some sort of scale that can hold a small compartment of water which you place the gem in and then it measures the strength of the attraction towards the magnet
I tried 5 stack of 10x5mm N52 coins on several pulled chzokralski rubies and all of it were weakly to moderately repelled by N52. High chromium? A couple of natural light blue cobalt spinels were also repelled, all were reddish purple under LWUV and inert under SWUV. Couple of natural vivid blue spinel were weakly attracted, all were inert under LWUV and SWUV.
I have a purple tourmaline that's highly magnetic and I've heard some purples turn electric "paraiba-ish" blue but I'm afraid to heat it at home. What should I do?
Verrrry cool! Just stumbled upon this technique awhile back for identifying garnets... Had about 30 small bright orange faceted stones, was unsure what they were, and they were comming up around sapphire/garnet on my refractive index scale... Saw that garnets have iron, so used a magnet to identify the majority of them as spessartite, and exclude a few presumed orange lab sapphires. SCIENCE! :D
I have some gems that pull with the magnet, but others that push away. The foam will be very still in water, but soon as I put the magnet near it, they start moving away from the magnet. What does this mean?
Excellent point. A few years ago a gentleman did exactly that, developing an identification scale based on the application of magnetic susceptibility as you suggest. Well done.
i think this technic its not work for all stone. i have try in a synthetic lab created its work with magnet as well and i test for a natural agate stone this tehnic not work as well i think that agate doesnt have iron mineral.
That puts synthetics in the easy as..FAKE category,lol. Till they catch on, and start adding iron:/ A very simple test for non experts to get a "bit" ahead of the massive synthetic stone, pain in the ass game:) Even rough stones, at the bloody mine, ive found to be synthetic for gods sake:/

thanks a lot it saves a lot of time and effort

I just watched your video demonstrating the iron in gems using the magnet. VERY COOL!
Thanks for demonstration. It is indeed a new concept in identification of gems from natural to synthetic and pretty easy to do as well as easy on one's pocket! 👍
Is red diamond can be magnetic or not..sir....thank you for your answer. 🙏
Very cool. Easy way to find the synthetics. Thank you.
that is very cool and awesome idea, I will be using this in the future
awesome presentation,thank you..

Great video, I love gemstones and peridot is my favorite, good info on how to check if it's real!!
Thanks for sharing this method

Very useful
Very interesting!!!
This guy is great most gem hunters wont even tell you this.They are hiding there knowledge so they can be greedy and take advatage of everyone.
nice video

Thanks for this, you're awesome!
hi sir. i am from india. this video is very nice. but can u pls tell me what the Metirial u used for this can u pls rply me. thank u
Very interesting.....I guess this test has a lot of scope !
Also will lab created gems move as well?

Try with the change of pole of your magnet.
Very cool, thank you :^)
thank you for shareng your knowledge
great sir
Nice
Thank you.
Bravo, thanks
Magnetic susceptibility test used in chemistry would be ideal to quantify the type and strength
Excellent point. A few years ago a gentleman did exactly that, developing an identification scale based on the application of magnetic susceptibility as you suggest. Well done.
Thanks a lots ...
i think this technic its not work for all stone. i have try in a synthetic lab created its work with magnet as well and i test for a natural agate stone this tehnic not work as well i think that agate doesnt have iron mineral.
Awsome :)
cool
with the force maghnit
am test same you i have black stone i think one kilo
Yes 60'/.OK
Will doen
