Ex. Dr. Miguel Romero
The larger specimen here is 1.4 cm across, and is a classic, sharp, symmetrical cumengeite of high value. The piece dates to older material found at the turn of the 1900s. The smaller specimen next to it is from recent finds (recent meaning in the Larson/Swoboda workings of 1973-1974), and is sharp and fine...but as you can see a bit different in habit from the older material. Either one, in this size, is rare on the market! This specimen from the Dr Miguel Romero collection was on loan exhibition to the University of Arizona Museum for over a decade, until my purchase of this collection in 2008. It was on display in special cases at the museum, and has since been featured in the book "The Miguel Romero Collection of Mexico Minerals" which we sponsored as a special supplement book (published by the Mineralogical Record in December of 2008) .
