I have a approx 5” x 4” x 3” piece of quartz with gold ore running through/around it. The piece weighs 1lb 10oz. The gold is concentrated in a few areas, as well as sprinkled all over the quartz. I measured the largest gold section and it was 2”x 1.5” of solid gold (at least on top, I can’t tell how far in it goes). My question is if anyone might be able to estimate what this might be worth. I’ve had an offer from a man who wanted to purchase it for $100, but I just didn’t know what to say on price. Any help on what this gold in quartz might be valued at would be appreciated.
