Mineral ExchangesWANTED! GOOD HAND SAMPLES

29th Apr 2010 16:52 UTCWilliam C. van Laer Expert

We are assembling systematic mineral "kits" for students and collectors alike.....need some fairly common minerals that aren't available to us locally: they need to be roughly 2" across or bigger, as pure as possible, and good examples of what each species represents (cleavage, luster, habit, color, etc.).


Some of the species we need to acquire, in amounts of 1-10 lbs.:

gypsum (needs to be good cleavages, not crystals like from Oklahoma)

anhydrite

halite

scheelite

vanadinite

malachite (massive)

azurite

nepheline

topaz

celestite

forsterite (massive peridot)

If you have access to a mine site or other collecting site and can provide us with any of these, please contact me here on mindat.

Also:

We could use:

pyrrhotite, ulexite (and other borates), wulfenite, beryl, and cinnabar. Wulfenite and vanadinite can be damaged and not suitable for sale to mineral specimen collectors.

To Torben Kjeldgard: Your e-mail address as given does not work! Please send me again or another if you have one, would be interested in the vanadinite you have!!

Hi again

I may have misspelled it.

My email is minhat_os.dk

I have looked after again and I have more Vanadinites.

maybe up to 20-30 and a lot of smaller specimens.

Regards

Torben

Howdy, I have a couple buckets full of gypsum (satin spar) specimens available. Thanks Bob
