A photo of this piece (together with photos of three others) appears on the cover of The Canadian Mineralogist Volume 55 No. 4 of 1 July 2017. On the inside back page of the issue, with reference to this image the Journal refers the reader to an article on pp.799-820 entitled “Recent Advances in Understanding the Similarities and Differences of Colombian Euclases” by Isabella Pignatelli et al. The “star billing” among the illustrations in the article is a good photo (on p.800) of the piece, which acknowledges it as part of the Budil Collection, but confusingly says it’s from the Gachalá district.
