    First....Welcome to the forum.

    What you have pictured appears to be of specimen quality (a naturally river rounded stone containing visible gold) and is probably worth more as is to a collector, etc. than the gold it contains. I would try to find a buyer for that and others like it before I considered crushing them.

    Good luck.

    If it can't be grown, it must be mined!

    Kind of what I was thinking. Gold is far richer when itís melted down, but to a collector who wanted a nice display piece it may be worth more than the gold youíve got in the thing. Because the problem is, you crush it, not knowing whatís on the inside of the stone, it very well may not have any gold inside of it, just whatís on the outside, and a few below the surface. I know crushing a 30 pound rock sounds nice, and all, but if thereís hardly any gold in it besides whatís on the top, youíll likely lose money

    In case you change your mind about crushing and want to set your own individual price(s) you can use the method described in the following link to obtain a close estimate of how much gold is contained in your specimen(s). https://www.gold-nuggets.org/specific-gravity-test.htm

    If it is gold it's free milling. No need for smelting, just crush and pan. You can do 30 lbs at home in a day for less than $50 in tools and supplies.

    I agree with the others, If it is gold just slab it up to sell. You will get many times the dollars you would get just crushing it for it's gold content.

    Heavy Pans

    I can agree with you there. Though Iíve only found one chunk of quartz containing gold, I wish now I would have slabbed it, because you get too fixated at the gold on the outside, and think youíre going to get rich, and instead your dipping your head when you find out itís barely over an ounce, and had you slabbed it you would have came out better.

    That does look like it would present well slabbed. White/black/gold.
    Would make quite a few pieces of jewelry possibly.

    Nice rings there IMAU...
    A water-worn piece of highgrade is pretty rare, much less 30 lbs of it. If it were mine, I would sort out some choice pieces by using a Falcon MD20 or a good vlf and cut the hot ones all in half. Now, you just doubled your number of specimens.
    After cutting in half, I would see what's revealed on the inside. If it's sexy, then I'd decide if it is of jewelry grade. Your one pic above looks like a good candidate. If jewelry grade, then slab and cab or have a lapidary specialist do it for you. You're now talking up to $30 per carat, depending.

    The material that isn't jewelry grade can still be sold as specimens if there is abundant visible gold on the piece. The richer the better, of course. With specimens, it's best if you can identify the location (provenance) of the piece, ie. "acme gold mine, boulder county".... and sell it to local collectors with that info provided so that they can create specimen labels and display them properly.

    The big names on the front range are Dave Bunk Minerals and Bryan Lees Collectors Edge. There are probably others.

    The material that doesn't make the cut as jewelry grade or specimen grade can get the 'ol crush and process routine for gold content. I like to spare the "lives" of nice high grade pieces that are found these days because the vast majority of it in the old days went straight into the 'ol crush and process routine.

    Nice find and good luck.
