First time I've seen one of these anywhere other than my buyer. I must say, this has to be one of the best inventions for precious metal buyers ever created. There are so many "rules" on precious metal that totally got obliberated when I started using this. Everything everyone "knows" about fake gold & silver is SO wrong lol.

A1. There are a number of ways to determine authenticity of coins,bars,other precious metals. Choosing correct method highly dependent on individual needs and what is tested. The counterfeits are becoming more sophisticated, so regardless of test the user must always exercise some caution. If you are coin dealer, careful inspection of the coin for dimensions, weight, stamp markings and XRF analysis will give you what you need to make a correct determination of coin’s authenticity....

I have a question, my family own a jewelry store in Vietnam, the market over here is crazy, so we really need some trustworthy gold analyzer. Here is my question, can Niton XL2 detect what is inside the jewelry, or a 2 cm thick gold bar? because there are jewelry maker that can make a jewelry that has different percentage of gold outside and inside. please tell me, I really need to know

I went to azom and then it lead me to another website of which it's difficult to find. I searched for it in the search box and found it on but it's listed as $32K+. Uh wow! I was expecting it to be expensive, but wow!

@vincecate “Although x-ray fluorescence (XRF) technology is generally considered a surface analysis, there are ways to interpret the XRF results to assist in determining if an item is plated. Analysis results will show the gold content of the plated surface, and in the case of most plated items a strong signal will also come from the substrate underneath the plating. These results often show a relatively low gold concentration in comparison to the substrate material. (continued next comment...)

Would this work if the item had diamonds in it?

@vincecate (continued from previous comment) ... In the case of heavily plated items, there are other methods in which XRF can be used to help identify these items. Your local Thermo Scientific Niton Analyzer representative can discuss these methods in detail with you.”

@polygamous1 They range from $13,000 to $24,000 depending on if its brand new/your source.

These things are awesome, mobile spectrometry

what about if the YELLOW GOLD has radium on it to make white gold?

Would this work if the item had diamonds in it? Also would this work if the item was plated? Thank You..

where can i take my gold to get tested by machines like this? the price of this thing is a bit much for my budget

See answers A1 and A2 ...
