Diopside (rare locality specimen) (ex Al Kidwell Collection)

Item Description

This is an excellent single crystal of the hard to find Diopsides from the Yates Mine. These crystals are virtually unseen in today's market. The piece was originally labeled as coming from "Huddersfield, Quebec", but this was often the case for these pieces, and you can see even though there is no actual locality at Huddersfield, it does have an entry that leads to the Yates Mine on mindat ( https://www.mindat.org/feature-5978122.html ). This piece is a well-formed, classic, sharp, semi-lustrous, rich green color, prismatic crystal of Diopside free of matrix. The piece is complete all around, but there is a contact on the back near the termination. I honestly think this is the BEST single crystal of Diopside that we've ever had to offer from this locality. A showy piece of this seldom seen material which dates back to 1977 according to the accompanying label from Art Smith. Priced at $1,600 in our inventory. Don't miss out! From the worldwide mineral collection of Albert Lewis Kidwell (January 1, 1919 - August 16, 2008). Al was a well-known mineral collector and research geologist with Carter Oil Company and later Exxon Oil Company in Houston, Texas. The phosphate species Kidwellite was named in his honor in 1974.
