C heck out this nugget from the California goldfields. It'll make your detector howl, that's for sure.
What an incredible center-piece for a large men's nugget ring. I currently have another California slug listed weighing almost 1/4 oz. It's even more rounded than this one; also a perfect size and shape for a nugget ring.M y sources say both were found in California - The exact origin of this one is unknown, the smaller nugget comes from Mariposa County. This globule is very golden in color, a good indication of high purity. I have not had it tested to determine exact fineness, but I would estimate in the neighborhood of 900 fine, a tad higher than your average 14K gold wedding band.
She's a classic slug of a nugget. The gold itself is a brilliant golden in color and, like so many weathered, river-worn nuggets, seems almost sculpted. I managed to find larger ones back in my mining years, but they were few and far between. This hunk is bound to liven up anyone's nugget collection. The gold is guaranteed naturally-occurring and, quite possibly, just as found.All my specimens show visible gold and are authentic gold nuggets or gold quartz specimens. Contact me indicating you wish to return the item. I poured through old mining dumps for years looking at orange-yellow-rusty rock through a loupe, but I never found a piece with visible gold.
Hydrothermal solutions carrying gold and silica crystallized into veins of gold quartz. This specimen comes from one of the many vein systems sourcing the immense placer deposits of the Sierra Nevada Mtns, the famed Mother Lode.

D uring my years of mining, I only ever found one platinum matrix specimen. I had it in my collection cached away for 15 years never knowing for certain what it actually was. I dredged it from the depths of the Trinity River, California back in the 1980s.
Going through black sand concentrates at the end of a season's dredging, I noticed an unusually heavy rock. After a long day underwater, thinking I'd examine it more closely at a later date, I recall throwing it into the bucket of classified black sand. Occasionally, oddities show up in your sluicebox, minerals or artifacts you can't quickly identify.
Meteorites, platinum nuggets, encrusted coins, diamonds, et al, if they're hiding down in the gravel, they get sucked up along with everything else. I had friends who recovered old gold coins and platinum nuggets up to 1/2 ounce from the Trinity, but at the time, I didn't realize I had scored one myself. Another platinum group mineral native to the area was irridium, a PGM mineral rarity recovered locally as small silvery flakes. Well, it took 15 years to cast out the last doubt about my find, but after a client had it lab tested, they confirmed my suspicions. It was the real deal, the only platinum nugget I ever recovered from the Trinity River.It was also the only platinum-matrix nugget I have ever seen to this day. Platinum nuggets, and both Kondyor Massif (Siberian) Platinum nuggets and gold-coated platinum crystals from the same region. The metal in my platinum specimen looked identical to Tullameen Pt nuggets, but none of those specimens had attached matrix. Knowing platinum is associated with Chromite and Olivine, I did some visual comparisons with different varieties of Olivine and the matrix attached to the metallic platinum appeared to be an Olivine aggregate.
The broader term, as one Tulameen miner-consultant referred to it, is Dunite. Dunite is roughly 90% Olivine.
Some crystals in the mineral complex were dark green, some lighter green and smaller in size. Size-wise, this specimen was roughly 1/3 platinum alloy and 2/3 matrix. By weight, the proportions were roughly reversed. Thanks for checking out our digs.
