My latest Lithographie just landed on my desk: "Smithsonite - Think Zinc!" I was amazed how many forms and colors this mineral can take on. Of special interest to me was the section on causation of color as this is something I am researching (specimens of green, pink, blue) -- the two page spread, 58/59 was especially visually appealing to me; I have been using those two crayolas extensively since kindergarten. One of the forms which was most intriguing is the one pictured in the middle of page 52, "crystal ball." Wow! How did that happen? The other one which appealed to me is on page 28 in Peter Megaw's story. Actually, this issue is just filled with spectacular specimens. It would be fun to see others from FMF member's collections, if they would like to share some photos.

Cheers!
Elise

Thanks...Smithsonite was a pleasure to work on, and Gloria a pleasure to work with. She's working on Topaz and Apatite, so if you have good shots, get them to her, she can only work with what people provide!

I do not own a single smithsonite - I can't afford to collect everything! I did, however, get the opportunity to photograph much of Bill and Diana Dameron's smithsonite collection for possible inclusion in the issue. Gloria was kind enough to choose a goodly number of them for the issue, but here are a couple of my personal favorites that didn't make it.

Today I was very happy to find that one of our specimens is a blue-green botryoidal form from Laurium, Greece; which from this issue's article by Wolfgang Wendel on the locality, seems to be very special in terms of history. For the Magdalena, Mexico locality, this same blue-green is said to be cuprian; I don't yet know whether that applies to that from Laurium. I hope to dig into the records to find more background information on the Laurium specimen and also hopefully to find more specimens in storage that might be brought out. Thank you for sharing such wonderful photos; I hope they continue to appear!

Cheers! Elise

As an avid collector of smithsonite for many years, I am enjoying the positively delightful group of specimens in this string. Smithsonite is a true love of mine. Thank you all for the beautiful pictures of your specimens.

Fur Elise. (Pretend there's an umlaut over that u)...


Good idea, Elise: Here are a few smithsonites from my collection. Feel free to comment, criticize, and elucidate.

ZnCO3 ps PbCO3-3.jpg
 Description:
Smithsonite ps. cerussite (sixling). 50mm by 45mm. Tsumeb, Namibia. I could use SWA, inasmuch as the specimen is from the first oxide zone, but I'll just go with smithsonite, why raise the issue, eh?

Here's a cute one, from Rush, Arkansas. This is basically a distorted single crystal, about 2 mm wide. Each end of the "barbell" has a triangular cross section, with the angles of one end oriented oppositely to those of the other end - would form a star of David if viewed end-on - fully consistent with the symmetry of smithsonite.

Wow!! Nice crystal Pete!! I had a calcite, a calcite from Charcas, that exhibited a similar property. Almost hemimorphic in nature, in that that the low-angle terminations were reversed, just as on your crystal.

Here's another, a couple of single intergrown crystals.

Thanks for sharing.

Ed
