Gold Silver Jewelry Tester Appraisal Kit 10K 14K 18K 22K 24K Platinum Palladium Test Precious Metals 999 925 Scrap

Like most families we have a few bits and pieces of jewelry, unpaired earrings, broken chains, etc. that have little value before but with the price of gold at all time high they are now worth testing and selling. The test kit is excellent, the solutions fresh and works great; at least for the gold which I used. I am assuming the same is true with the silver and platinum solutions. I’m not a jeweler but the kit is easy to use and seems to do what it is designed for which is all that matters. The price is very reasonable and the delivery was very prompt.

Very Good & easy to use

Bottles are small, but it works as it should and seems to last. Would be nice if it came in a case to keep it in/ store it in.

Everything about this kit is excellent, except for one tiny detail – when I opened one of the scratch plates for testing gold, it had some residue or some type of crud on the surface – it wasn’t the clean black testing plate I expected and I’ve seen before. Luckily they provide three or four of these testing plates, which is nice. The kid includes acids for 10K, 14K, 18K, 22K platinum, silver, and a neutralizing acid. I’ve already put this into use and it has revealed that a necklace I thought was just gold tone is actually 14 karat! I was using years old acid to test my goal which is a no no. You should be replacing your gold and silver testing acid every six months or so. Well worth the investment, especially if you find yourself in a situation like I did – especially with unmarked metal, You might be in for a lovely surprise. If you don’t know what the gold parody might be, lightly scratch the piece on the stone and start with the lowest purity acid - 10K. If the acid doesn’t destroy that gold scratch, move up to 14K. Then move up to 18K (you lucky lucky dog!) if you don’t see any smoke or gold disappearing from the initial tests (the acid will destroy the metal if it does not have the level of purity it’s test testing for.)

Great test kit for gold and silver. Easy to use, but be careful with the chemicals, need to use gloves! The bottles are pretty sturdy even though they're plastic. These are good sizes that can be used several times for testing.

Love having this in my home to check jewelry

have a jar of scraps and odd stuff collected at work. kit was paid for first test i did.

I was a bit disappointed in this product. We have bought acids from them before, but the 18K did not perform as previous bought. The Silver Acid is shown to be red in the instruction manual. However, when you use it on a black stone, the color does not show up. Perhaps instead of sending two black stones, maybe one should be white, so that the colors show up better. It does if you use it directly on the product itself. I prefer not to do that as acid has a tendency to leave a mark if the item is not good. This does have effect on costume jewelry and can ruin a piece. However, it did work for 10K and 14K. The stones also are different from our original stone and I feel it doesn't quit react as well. It has a slightly soft top layer and I am used to a solid hard layer. I was also expecting larger stones, but that was my fault for not reading closer. I will keep this kit as a backup for when I travel, but will still use my regular stone at home. I did like the variety of acids, which had some I never had before. It is ok for a starter set.
