These crystals are to 6-8 mm in size and are nice and fat as well. Previous examples have usually been at the 1-2mm size level or less! The matrix was extremely loose in the pocket and so nearly all recovered specimens are thumbnails (from which I cherrypicked the best 10 or so - below). This was one of the two best larger specimens of Nenadkevichite which I was able to obtain from Gilles Haineault , which were collected by him in July of 2003. However, with delays for prep and analysis, I only heard about these amazing specimens this summer.

These crystals are to 8 mm in size and are nice and fat as well, with sharp terminations and good lustre! Previous examples have usually been at the 1-2mm size level or less! These are off the charts for the species. The matrix was extremely loose in the pocket and so nearly all recovered specimens are thumbnails (from which I cherrypicked the best 10 or so back at the time). This was one of the best larger specimens (in terms of XL size and overall coverage) of any I know to have sold, all of which were collected by Haineault in July of 2003. However, I missed out on this particular specimen which went into the MSH collection of James Zigras, from whom I recently obtained it in exchange. The identity has been solidly confirmed and they stand as exceptionally beautiful and significant examples of the species. Matrix associations include superb twinned epidiymite crystals and aegerine.\u003C\u002Fdd>\u003C\u002Fdl>\u003C\u002Fdd>\u003C\u002Fdl>",{"id":247,"source_url":248,"license_code":169,"credit_html":249,"title":250,"description":245,"author":173,"original_width":210,"original_height":251},53247,"https:\u002F\u002Fcommons.wikimedia.org\u002F?curid=10460916","Robert M.
