Gold buyers generally only test using 10k, 14k, 18k, and 24k, and they only pay at the lowest test it passed. If you have a 22k chain and it passes 18k but not 24k, they are only going to pay you at the 18k rate and will pocket that extra 4k's worth when they sell to their wholesale buyer (usually by melting everything together and selling at exactly whatever k weight it all averages out to. They won't mention that they are only paying you for 18k, they just give you that price on a "take it or leave it" basis, and let you assume it the price for 22k because that's what it is stamped as (and is), but who ever checks their math? If you do check their math, they will say they can only determine it is at least 18k, and so "take it or leave it", and most people then take it and screw themselves. Here's how to easily and quickly use their own test solutions to figure out exactly what k it actually is, so you get paid accurately. Lets say you have a chain you believe to be 19k, so after it passes for 18k, you need to prove to the buyer it's 19k so you can get paid accurately, but there is no 19k test solution. Well by mixing up the appropriate ratio of 18k and 24k solutions, you can make a solution for any k weight in between 18k and 24k in just seconds. Here's how: Let's start with a 1/1 ratio as an example: 1 drop of 18k solution and 1 drop of 24k solution equals 21k... The different solutions are just different ratios of Nitric acid to Hcl acid, and you can mix them to get any gold content you want by simple math. Say your piece passes 18k, but it is supposedly 19k. The difference in k's between 18k and 24k is 6, so 6 is you base. To get 19k simply mix 5 drops 18k with 1 drop 24k (6 drops total) and then use one drop of your mix to test with. In this case if it stayed yellow with that 5/1 solution you made, you know it is at least 19k, so then you would try for 20k, by mixing 4 drops 18k to 2 drops 24k. If it ate the yellow you know it is 19k because it failed at 20k... 14k and 18k are 4 k's/drops apart, so you will be base 4. For example, 2 drops of each solution creates 4 drops of 16k solution, (but so does 1 drop of each...), 3 drops of 14k and 1 drop of 18k makes a 15k solution, and obviously reversing that ratio makes a 17k solution. The same ratios would apply between 10k and 14k solutions to make 11k, 12k, and 13k solutions. So am I your friend or what???? :D

The acid can be neutralized with a little bit of water and baking soda if it gets on the skin :)

BTW: Most older and/or high quality jewelry is usually about 1k more than it is stamped as. Newer and/or lower quality pieces generally are what they are stamped as or a little less...

This is a gift. Thanks.

Nice breakdown Sandro, thanks!

@VolcanicDrum Thanks for the review! Glad you enjoyed the info and the video! Cheers!

THANK YOU for your honesty ;)

I'm going to try this. Great video, thanks!

One of the truest, best and simplest gold videos on KZfaq. Spot On!

Dude, You should be starting with the next lowest karat solution from what the stamp says. or you are wasting the gold. You only want to rub it once. If you start witht he highest solution, you will have to rub it again and again. If it is 14K start with the 12K and then move up to the 14K. Solution is cheaper than gold!

Nice explanation of a 'Touch Stone' for testing a gold alloy sample. As you know 18 carot gold is 18 parts gold and 6 parts copper or silver to make a total of 24 carots. Green gold, an naturally occurring alloy called Electrum is alloyed with silver and copper. Rose Gold is alloyed with copper only. Yellow gold [18/6 ratio] is alloyed with fine silver only.

Awesome video... So many people getting ripped off... 10-15% below spot is always pretty fair.. Thanks Again!!

Very educational

In that business they cut your jewely to check if it has gold inside, but that testing if pretty much like they do to verefy what type of gold, etc.. Nice vid

No! Keep the gold, unless you're desperate.

A very useful video, thankyou.

Awesome, I'm bookmarking this. It's always nice to know what you have. Thanks! I already have a scale and it was only about $14, so it makes sense that you got a good deal.

Well done, Great explanation. I wish there was less back ground noise.

Great big Man-Hug to you Sandro. This is info I have always wanted to know. Cheers mate.

Excellent, here's a tip too: Use a windguard on your mic :)

That's a very interesting and informative vid for a novice. Yes, it is worth it to buy all those testing solutions , scales etc via Ebay. KudosMr. Marino.

Good job

great video

Great info Sir, thank you very much.

nice video, ty

@KingsWorld2010 I'm not using an open container of the stuff, and an eye dropper is easy to manage. A drop of the acid won't kill you, just clean it off of you so it doesn't burn your skin.

thanks, great!!!!

All those items can also be found at your local head shop! (Even the chemicals if you go to the right ones!)

Very nice testing friend. Informative video. Regards,

I think your demonstration is very comprehensive and I thank you for making it know to the public. Please where can I check the current prize for gold? I really need to find out as I represent a group of ilitrate villagers that has some gold dust in their possession.

you forgot to file it first. then for proving firstly there is no steel in it.. it is always good practice to see if it is magnetic. it is just smart for demo because if its magnetic. it is not gold and dont waste risk of acid burn etc... good other wise

Take a propane torch to .999 pure gold. It will not discolor and retain its shine. Jewelry marked at 10 k or so is probably actually 9k or less which cannot be sold as gold. Gold nuggets have more value than bullion only because they are nuggets which people feel have esoteric value.

Thanks bro!

This is perhaps one of the most useful reviews I have ever read.You just taught me how much to expect from selling my gold! There will be no surprises from here on out! I like knowing this useful info. I did already have a testing kit, I had to ask the owner of a local pawn shop where they got theirs from, and she said e-bay, just as you did! They did run a magnet over my silver to test it, but also checked the stamp it had on it too. I wasn't sure if there was a chemical to test silver or not until I went online to buy the gold test kit. Thanks again dude, I really appreciate your time on sharing this! BTW, your chain looks really nice on you, and 21K is not easy to find in my area. I have a 21K piece that I purchased in Iraq however, wish I had bought more, gold was not as expensive then as it is now, but on a army sergeants salary, I did great to purchase one or my wife. Thanks again.

Good video.

can you show me the link of that scale you're using? I searched ebay and couldn't find the one you have

I was the 1000th like !!!

@huskerbird1 just search gold testing

Link to who offers that kit at that price on eBay? Sounds a screaming deal! Great video!

Ucher Harris kitco.com he said it in the video

really classy video

nice ifound it quite helpful cos i can sell gold if it is real.LOL

oh

Awesome new way to make money with gold! www.Goldmoneytoday.com/newlifestyle/SaveInGold

Informative film and important in today's economy.

Hey Pilgrim, I bet there is an interesting story that goes along with the scar on your scalp! Thanks for a very informative, quality video. Pete

You can buy a bitcoiin with all that gold
