Quartz / Gold & Hydrofluoric Acid

Recommended Posts

wow.....amazing stuff....looking at the quartz and gold as you found it you would never imagine that it would have all that gold in it. Thanks for sharing those pictures..pretty cool, Steve, I am going to try that first....maybe WINK would expose some of the gold near the surface.

That's why I chose to hf this specimen. It did not look good on the outside, but the continuity tester told me it was all connected and the specific gravity test confirmed how much gold was in it. That was the topic of my article in ICMJ.

Now if you just want your nuggets to shine I've found that white vinegar will do it. I put them in and every couple days I'll turn them over. I just keep them in the vinegar until I'm happy with the way they look

Anyone using hydrofluoric acid in high concentration form please be extremely careful even if you know what you are doing. It's bad if comes in contact with your skin, bad if you breath the fumes, it will eat through glass containers. Any specimen that have been treated using hydrofluoric acid, the specimen need to be neutralized. Unless you know and fully understand all the risks don't consider using hydrofluoric acid for treating gold specimens. Again please use caution when using this stuff.

Looking for any information on who provides lab services to clean mineral specimens in California. I am sure I am can't be the only one interested in such a service. i won't mess with this wicked and nasty chemical, but some Quartz with gold specimens would look a lot better with an acid treatment.

      Ok.  I got the individual tables posted so with all this information you should be able to identify both the type and weight of any rock you might find in a jewelry item.   I got all this information from a gentleman who went by the name, 'Pawnbroker _Bob' on Tom Dankowski's site.  Its been a long time, several years, since Pawnbroker _Bob has posted and I haven't been able to get a hold of him for permission to repost on this forum so I am going to link his Forum post here, along with all the table posts I've made so you can find this stuff in one place when you need it.
      I'll just tell you that its pretty cool to id and calculate your own gem stones, and speak with a little bit of knowledge when you are showing them or trying to sell them.
      Start with Pawnbroker _Bobs post and then reflect on the tables.  I would encourage you to save this info into your own personal libraries.

      Hi all, 
      This info was shared with me by Pawnbroker_Bob from the Tom Dankowski site in PM's back in 2012.  
      Gemstone Characteristics Table
      We have compiled a listing of the scientific characteristics of many different gemstones. This is a chart that displays at a glance the important information about each classification of gemstone and it's members. Enjoy!
      Gemstones
      This is a fairly comprehensive listing of gemstones with their specific gravity, Mohs hardness, index of refraction and gemstone family classification in alphabetical order. We color coded them to help differentiate between them (these are approximations and subject to error).
      Specific Gravity: Specific gravity is the number of times heavier a gemstone of any volume is than an equal volume of water; in other words, it is the ratio of the density of the gemstone to the density of water. For all gemstones listed in this table there is a scientifically determined specific gravity. You can use the specific gravity and a couple simple measurements to estimate the carat weight of a stone.
      Mohs Hardness: Hardness can be tested through scratching. A mineral can only be scratched by a harder substance. Therefore, a relative scale can be established to account for the differences in hardness simply by seeing which mineral scratches another. That is exactly what French mineralogist Friedrich Mohs proposed almost one hundred and seventy years ago. The Mohs Hardness Scale starting with talc at 1 being the softest and ending with diamond at 10 hardest, is universally used around the world as a way of distinguishing minerals. Simply put - the higher the number, the harder the mineral.
      Index of Refraction: All materials refract light, ie alter its angle. The amount by which light is refracted is an important feature of every gemstone. The measure of a material's refractivity is known as its index of refracton (R.I.). Without going too deeply into physics, light travels at different speeds through different media. When light passes from one medium to another, its path is altered (bent) and it is said to be diffracted.
      Gemstone Family Classification: The gemstones listed here show every color in the rainbow. Even with such variety of colors, patterns and shapes - they can be broken down into 16 different families based on their chemical composition.

      I was going thru my junk and found a gold bracelet that I had always thought was gold plate cause it was mostly brown with some yellow underneath? On closer examination, the clasp is clearly marked 14 K underneath by where the chain attaches and it does feel heavy. I got this ages ago with my Tesoro Lobo, before I had a metered machine.Just tested it with my MXT and 6 x 9 coil and it reads VDI 26-30, Pulltab/Ring on Coin mode and in Prospect mode,it reads 10% iron id which sure sounds like nonferrous to me...Does 14 K gold really corrode like this? How do I clean it up? Maybe I better take it to my coin dealer and see what he will give me ? It is about 8 inches long, 1/4 inch wide and 1/16 inch thick. Photos attached,taken with my new used Canon SX 50.
