Please Note– We Recommend that Customers should come down and look at product in person before ordering. None of the products are “washed” but they are screened to size, and they could be dusty or contain some fines. Also this is natural rock and with that colors can fluctuate slightly as digging moves across the different veins in the mountain. Therefore even the same rock over time may have slightly different colors.
