bought a ring for 20 bucks at a yard sale the lady says she thinks its fake so i took a chance....asked a jeweler to test it but he said he could tell its fake because i paided 20 bucks...bought the kit just like yours...says 18kg stamped did what your video showed and wow it is real....so happy...got a large 18kg ring for 20 bucks.....so much for the jeweler lol Thank you........
I know this comment is as vintage as the $20 ring BUT* So the Ring was stamped 18k and the original owner never even bothered to get it checked out? Wow that's amazing.

I bought the kit and also bought a rolex and everybody told me it was fake because I only paid 800 dollars and on the bottom said 18k and I just tested and the stood the 18k acid but it was dissolved by the 22k acid, my god the rolex is real!!!!!!!!
So the last hold is what it is? If I'm testing 14kt and the 18 gets ate up and the 10 and 14 are still showing it reverts to last hold which would be 14kt? Btw great video
What if you have a rare gold coin you want to test without scratching it? Also if something is plated with real gold, how do you discern what is under the plating is not gold? I mean, if you scratch the gold plating it will test as gold, but underneath it could just be lead lol or some other metal.
I have a bar my grandpa gave me before he passed. He was a retired American electrical power employee. He said it was a thermo electrical somthing. He said its made of gold palladium and silver. Iv acid tested it with platinum acid in a test stone and it stays for a while but the metal will float to the top after a while. Any thoughts
I want to know the same thing as AOG Critical Logistics Inc. - what happens with BRASS? Will the acids eat it away as well? React in a different way? Or will it give a false positive?
Hi! I got an acid test and I have a gold ring that is stamped with “ALASKAN GOLD” but no gold content stamp(kt).. So I did the 10 and it didn’t dissolve, the 14 faded a little, but took a while.. Did the 18 and it completely dissolved. Started to smoke a bit too.. Because I just got this kit today, I tried the 22k acid and it didn’t dissolve. So I’m kinda confused here.. Say it’s 14k, is any testing beyond that just invalid? Instructions aren’t real clear expect for the basic of basics
Hey I have a "white gold signet ring very old n homemade it's un semetrical there is no markings on the ring at all! But I have acid test at my home and the only thing that eats it away is 24k and platinum! 18k does not effect it and neither does silver acid. How do I make sure it's not stainless steel
"I'm just going to rub it on the stone aand, oh wait, it looks like my 75 year old mother is already doing it... wait, oh god, those are my hands!" ha ha ha...
I was sold a fake sterling silver and the 18k solution turn blue so that doesn't mean is real silver it just mean silver turns to blue with the 18k solution.
I mean gold doesn't get damaged if you scratch it like this. I work at a jewelry shop and clients always come in worried that it'll scratch or break their gold and I'm always like ...no, if it's real gold you shouldn't be worried about damage.
@@MadMax-us9ih have you ever put it under a microscope? It does scratch. that is why its left on the stone and you can tell if its silver plated, because you wore through the plating. most buyers just sell it for scrap instead of sitting on it...quicker money
Heard if you scratch 10k or 14k hard it will not pass the test because you scratching the non metal and from my experience scrating antique gold or even dirty gold it won't pass so try cleaning the gold good before testing and clasp or bail clamp my stock to magnet because the spring inside is not gold it will pass the acid test.
I was wondering,. I have an .750 stamp (18k) gold chain I just picked up a Puritest kit of Amazon the acids are JSP brand... So the gold didn't get "eaten up" it just sort of lifts off the stone and flotes in the acid, is that alright or is the gold supposed too stay on the block? Thanks for any response!!!
Thank you so much for the video. I don't have a clue about this testing thing; but I collect old stuff and I enjoy finding treasures along the way. I bought the materials, even a microscope 60x , and i am not much closer to be sure of my metals as I test them, I do have now a full set of fingerprints:) My question is; Do these acids like 10K one also melt other metals like brass?
Thank you Kendall for your video ;-) have you ever tested sterling with acid, both using 18k acid (blue results) and silver acid (red results) and getting positive results with both acids, but for example, the charm is marked 925 Italy with a reputable hallmark and the charm is "magnetic"...is the coating that prevents tarnish causing it to be magnetic? I read somewhere that the coating is rhodium and is magnetic...I actually keep scratching until I wear away the coating to get the positive silver results, if I just do it the first time it is negative since I am just rubbing the coating on the stone, after a few times scratching on the stone it eventually shows it is sterling, what are your thoughts and experience? Thanks so much ;-)
seems to me 22 kt acid would only eat up 1/2 the gold sample if it was 12 kt. (leaving the actual gold content behind. If 22 kt acid eats it all up ,then I would suspect NO gold content?
I think that gold is a noble metal and no acid "eats" it up. I think what ever gold is left is the content. Say you scratch a 1/2" square with jewelry, then whatever acid you used eats away all that is not gold. Now say you only have 1/8 square of gold left, you figure the percent/ kt left on the block
A lot of places wont take 10k scrap, but it's still worth testing for, because alot of people like it seeing as the lower karats in gold, the stronger it is. That's why 14k is the most common in a lot of places, looks good enough and doesn't get dinged up as easily.
I have a question. My sister gifted me a necklace she tried in the pawn shop which has a huge area blackened. How do I clean that portion so it becomes all shine like the rest of the necklace? Thank you!
Toothpaste with baking soda and scrub it with an old toothbrush. Or dawn dish soap mixed with hot water. And scrub. If it's gold and it is blackened, it's either fake or plated. The test they did ruined the jewelry. It can be polished out with things listed above, but may have removed plating from the piece.

So what is it what they don’t want you to know??????!
They don't want you to know that you're not going to find out 😂
They don’t want you to know to wear goggles while acid testing. 😅
Does it damage the item when you scratch it?

Make a deep scratch and test it again. Some GF will test positive, much more on watches as they put a “thick” layer of gold. Most watches are GF
Some types of stainless steel will pass
Lol doesn’t mean it real but atleast the gold is
@@louiet4905 bingo.
So the last hold is what it is? If I'm testing 14kt and the 18 gets ate up and the 10 and 14 are still showing it reverts to last hold which would be 14kt? Btw great video
After put acid and add sea salt if sea salt colour will be yellow it means pure 22k gold if not it means not gold.
Hi can I ask which acids range bottles I need for testing
Can you reuse the scratching stone? Or do u need a new one for each piece of gold?
yes the scratching stone can be reused
What is considered clean and uncontaminated? Cannot have residues to confound current testing.
Would it be the same acids to test for white gold ?
What if you have a rare gold coin you want to test without scratching it? Also if something is plated with real gold, how do you discern what is under the plating is not gold? I mean, if you scratch the gold plating it will test as gold, but underneath it could just be lead lol or some other metal.
Scratch deep enough to get the plating off
Powerfull magnet. If it attracts, it's plated.
Only on ferrous metals. Stainless steel gives a weak magnetic response, as do some platinum/iridium alloys.
@@BenYamunma
my question is where are you buying real gold for 1$??????
Goodwill darlin!
I have a little of it on my skin. What is the best way to wash it off?
What’s the square blocks your rubbing on
What is the black stone you are using to test
I have a bar my grandpa gave me before he passed. He was a retired American electrical power employee. He said it was a thermo electrical somthing. He said its made of gold palladium and silver. Iv acid tested it with platinum acid in a test stone and it stays for a while but the metal will float to the top after a while. Any thoughts
If flakes or specks swirls your puddle it's still a good sign as well but maybe a bit lower purity
How much in to include black stone for testing?
What can you use as an alternative for a testing stone. I have acid, just need a test stone alternative...
What are you rubbing the gold on
Why it have no 16carat acid test?
What does it mean when it wipes away black on a towel....did the chain puddle flakes some in 14k and not so much in 10k
I put the acid direct on a small part on my chain and it changed to like a copper color ? What does this mean
I want to know the same thing as AOG Critical Logistics Inc. - what happens with BRASS? Will the acids eat it away as well? React in a different way? Or will it give a false positive?
Hi I worked buying and selling gold and brass will fade away
How to make this acid solution
Why would my ring pass every test but the acid test. The pawn shop said it was copper but my finger never turned green.
My chain is the same . Did u get a result ?

thank you Kendall what acid concentration did you use?
What if NONE of the acids dissolve the scratch?
Then you have 24k. Huzzah!!! Congrats!
Do the tester pens work for gold and silver testing?? Please
What is it when the acid turns green on 9ct gold when testing?
"I'm just going to rub it on the stone aand, oh wait, it looks like my 75 year old mother is already doing it... wait, oh god, those are my hands!" ha ha ha...
Does scratching the gold on the stone scratch the gold?
I was sold a fake sterling silver and the 18k solution turn blue so that doesn't mean is real silver it just mean silver turns to blue with the 18k solution.
and they scratch the hell out off it before they even make an offer

new england patriot but not damage it as in completely destroy it or even that noticeable🤦♀️

If the acid eats at 10k and 14k could the item be like a 6kt or 9kt? Or does that mean it’s not real gold
10k in many places is not even considered gold anymore.
In other countries they consider 9 kt as gold.
I was wondering,. I have an .750 stamp (18k) gold chain I just picked up a Puritest kit of Amazon the acids are JSP brand... So the gold didn't get "eaten up" it just sort of lifts off the stone and flotes in the acid, is that alright or is the gold supposed too stay on the block?
Thanks for any response!!!
It could be gold plating not solid gold
So when the particles float to the top it is GP, IS IT WORTHLESS?
@@GoFarFarAway. yes, worth less literally but still nice to wear
Mean that you need to use a reference test with a gold of known purity to compare. As it might be just you
Should try it with 14k &10k because fake gold will dissolve completely.
Bought this kit for when I find jewelry at the goodwill or OfferUp .
Sir acid ka naam bataiye

What if i use the acid test and the gold slowly goes away
Then you get the sad trombone music...

The gold is not gone, but it is the acid dissolved.
Who is "they" and what is it they don't want to know exactly? If it's how to do acid tests on gold - you have it covered.
Thanks for the gleaning gleams lesson
How come nobody talks about or shows how to CLEAN the really HIGH quality gold like 24k off the scratch plate???
looks like it is eating it up? it did eat it up.... and if it ate it up at 14 you just wasted 18k acid you do not go up you go down..lol
I think that gold is a noble metal and no acid "eats" it up. I think what ever gold is left is the content.

Thanks for the video. It helped a lot. I was able to test the gold I had and will sell it more condident.
Thanks for sharing
Thanks for watching!
Best BITCOIN commercial ever
How many times should you test a gold chain to make sure it’s not gold plated?
So is that all clear now?
So if the 14k gold acid eats up the gold it's most likely fake?
No it might as well be because the value of it is so low
A lot of places wont take 10k scrap, but it's still worth testing for, because alot of people like it seeing as the lower karats in gold, the stronger it is. That's why 14k is the most common in a lot of places, looks good enough and doesn't get dinged up as easily.
I have a question. My sister gifted me a necklace she tried in the pawn shop which has a huge area blackened. How do I clean that portion so it becomes all shine like the rest of the necklace? Thank you!
Toothpaste with baking soda and scrub it with an old toothbrush. Or dawn dish soap mixed with hot water. And scrub.
If it's gold and it is blackened, it's either fake or plated. The test they did ruined the jewelry. It can be polished out with things listed above, but may have removed plating from the piece.
@@ChfBgTlk Ok, I'll try it thanks. Hope it won't damage it more. Is gold for sure since my sister works with gold and I got it as gift for Christmas.
Where can i sell my gold at spot price
