Stunning find, Lunk!  Did you use acid on it or did just water clean it up?

I would not use acid on a limonite crystal as it is Fe . It is great  to get a three-some.(Quartz,Gold and Limonite  crystal) The black crystal is what we call devils dice. My favourite three-some  find is below, the silver/dark grey one is Tungsten or wolfram

Tungsten has a similar Density to Gold

3410 °C

Boiling point

Don't suppose you have waved a Gold Monster or a Nox 800 with small coil over that area?

I’ve actually used the Nox and the GM 1000 at this locale, both with their small coils. Must have just missed this particular spot before, as the speci was right on the surface. Happy Holidays to you.

As Geof noted, I didn’t want to use any kind of acid on the limonite, so I just used a gentle scrub with a toothbrush in soapy water.
