That's a fine specimen, Jordi. I wish it were one of my duplicates!

A Medici family field trip to a pegmatite in an apple orchard in Albany, Maine yielded a couple of interesting specimens, a tapered common beryl (for which this pegmatite is noted) and a cat's eye beryl which was found loose in an approximately 15cm long, 3cm across void (apparently the gem core of a larger common beryl).

The garnet is probably not from Rumford. The grossular that is known from there is very poor. Similarly, it is not like the grossulars in calcite from nearby Carthage. When I first saw your specimen, i thought it was from Casco, although it could be from Limerick.

This tourmaline is very atypical of the Dunton Quarry, especially the termination. Many dealers sell Brazilian crystals as though they are from Newry. If this were from the Dunton Quarry, it should fluoresce in SW very bright bluish white. Can you post a SW UV picture?

What about the Pitts and Tenny Mine, Minot? Some grossulars I have collected there are quite similar.

Hi Pete,
The crystals are different to my eyes as is the matrix. I wouldn't consider Pitts-Tenney as a source. The color shade is certainly unlike Pitts-Tenney and very much like the grossulars that occur south of that area. The emergent diopsides on the crystal faces are very different as well. When the Pitts-Tenney crystals show these emergent diopside "inclusions", the matrix is not calcite rich and the grossular forms a solid layer under a crystallized grossular surface. That matrix is frequently etched as well.

Thanks Van. I already added "?" to the locality (in https://www.mineral-forum.com/message-board/viewtopic.php?p=17972#17972 )
It could be reasonable re-label it as from Casco?

Sorry for the confusion. I didn't remember there being two different garnets on this page. The Phippsburg specimen looks OK. The "Rumford" one still looks like it is from the Casco or Limerick localities. Maine has a fair number of large grossular crystal localities.
Best Wishes, Van

Excellent. BTW When writing a reply to a post, the "reply page" is different than the posting page. You must leave the page where one can view the images/comments. It is helpful to refer back to the images when writing comments. Yes, the writer could open a new tab, but when one has a lot of tabs already open, this can be inconvenient.
Best Wishes, Van

Is how phpBB works Van. It has some advantages and some inconveniences as every software.
We improved (and we are still improving) phpBB A LOT and it waste thousands (sic) hours of our life, so probably some inconveniences will remain because every time we touch the original source code, many unexpected disasters happens and our work time is limited (only 36 hours per day ;-) but anyway, we note your suggestion and hopefully some future day we can apply it (I don't promise it!!! ;-) ;-)
