Different Kind Of Nugget Found W 24k, What Would You Do?

Recommended Posts

I like em just the way they come out of the ground.  i'd leave it natural.

I do not think of ANY native gold as "ugly" ... all of it is beautiful. I agree with beatup -- keep it natural. I'd place it in a shadow box with other nuggets that are different in appearance and have the box on my coffee table.

One of the things that intrigues me about natural raw gold is the many offbeat ways nature creates Au.  This rare (to me) almost sheet type gold is a 1st.  It looks as if the liquid metal cooled right between two quarts seams and then just popped out.  You can still see small rough white quarts crystals still attached to both sided of this beauty.  YES it is!  You may think it is ugly and that is fine, but since I own it, I say it is a beauty.  Just bigger than my thumb nail and weighs in at 2 grams (30 grains) and was found with the 24K while using the 6" concentric coil at about 8" depth.  This one is an Idaho piece and a little unique compared to the others found in years past at that site.

I'm wondering if I should tumble it a little to get a bit smoother shine or use a wire brush to add a little sparkle or leave it as is?  What would you do with something like this?


Hi Gerry… congratulations on a very appealing find. Your specimen is attractive precisely because the gold contrasts so nicely with the white, crystalline quartz.

I would avoid any form of hydrofluoric acid treatment that would attack the quartz crystals for that reason alone. A rock tumbler could damage both the gold and the quartz depending on the abrasive material utilized. The gold notwithstanding, we don’t want those handsome quartz crystals irretrievably damaged. 

It really is better to avoid any treatment to naturally attractive samples such as this one. That said, what you want is easily achieved with very little risk of damage.

First option before attempting the technique described below for such a small sample, might be to try swirling the specimen for a few moments in a vinegar / table salt solution. I doubt it would attack the quartz crystals but ought to brighten the gold. Similarly, oxalic acid will remove iron stains without damaging the quartz. It is the standard treatment for this purpose used by serious collectors.

From the photo at least, the gold could be somewhat delicate, but you might safely use a light gauge circular wire brush without incurring any serious damage. It's a bit risky on such a small sample. These wire brushes are normally supplied with small handheld rotary tools (dremel for example), and without checking mine, I think they’re about ¾ inch diameter or so. Use a slow speed setting, and only allow the brush tips to touch the high points of the gold. Apply no pressure. This will produce an attractive light luster, particularly on the gold high points.

The silver sample below is much larger of course, but in appearance is somewhat similar in shape and structure to your gold specimen. It looked very much like your sample insofar as the silver was quite dull with no luster worth mentioning. Below is the final result after using a circular wire brush, but where some light pressure was applied because the sample was sufficiently durable to support it without risking damage…………….. Jim.

I would try oxalic acid ( very strong mixture with water) to brighten the gold and remove some of the iron oxide or try Whink that has a small concentration of hydrofluoric acid for somewhat more aggressive cleaning of the gold, removing iron oxides and dissolving some of the quartz. If you use these two methods it will take time to see any satisfactory results, so be patience.  If you have some hydrofluoric acid in a higher concentration (48% strength or more) you will have faster results and would need to monitor closely so you don't destroy the specimen. But be extremely careful when using any type of hydrofluoric acid in any form, the acid is deadly and I mean deadly, you better know what you are doing! Finally soak the specimen in baking soda if you use any of the cleaning methods above. There are other methods that can be used to also give a wow look, but I would need to studying the specimen first hand on what would be the best course of action to take.

Very nice find!

Nice nugget with very fine particles of gold I'd name it the "sand nugget" clean with a tooth brush and and call it good. You've been busy Gerry I cant keep up with all your finds :biggrin:

Congratulations Gerry, that`s a terrific 2 grammer ?      I would probably leave it the way it is, I think it looks pretty good now.

      PART ONE:
      Pictured below are four gold specimens that I have found and I will discuss what methods I use to remove the host rock revealing mother nature's treasure. I gave each specimen a "letter" designation so you can follow the progress from start to finish on each specimen. Part Two I will discuss the chemicals and equipment I use to clean gold or mineral specimens.

      By using $1800 for gold and $28 for silver as a base a common dime would have a value of 2.02 and a .6 grain (not gram) nugget would have a value of 2.02 if it was at 90% purity.If you want to know the silver amount of a common dime  multiply .07234 times the   spot price of silver.A  .6 grain nugget is tiny.  I  would rather find a nugget then a  silver dime any day unless it is a very rare silver coin.I  imagine you nugget hunters  stumble on to a nice coin  now  and then.I heard Tom Massie found a $20 gold piece when he was nugget hunting.I hope I did my math right.Even with  copper surging to  $4.06 today a  common dime only   has .27 cents  of copper in it.

      What is, if we should, get the dark crust from an old liberty dime to determine date and other details. No scrubbing with steel wool? Acids? Thank you in advance here at this forum for any help you can give.

      So I was killing time eye shopping gold nuggets, I like looking but never buy any until now when I saw what I thought was a really beautiful 29.32g gold nugget pendant. This one was full of character and had a variety of color and texture, the simple silver wire mount cleverly wrapped to hold it securely without solder or permanent attachment the perfect gift for my wife’s birthday. Well, it came in the mail today and for reasons beyond comprehension he decided to clean it. The silver mount I guess melted in the acid, it looks I think much less interesting and the weight is down to 26.2g from it’s natural state at 29.32  a little of that lost fine gold. I’m sure I could return it the seller is very reputable but still like it just not nearly as much, what do you think am I wrong thinking it was much prettier before it was cleaned...should the seller have even done this after posting the pictures in his add?

      I have 3 batches like this. I just listed one on CL for 175.00. Almost all iron items with some brass, ceramic etc. Priced too low? Too high? Going to be getting rid of all my old finds soon. Any ideas, opinions are good to hear. Thanks.
