Item Description
Donnayite-(Y) is only found in about a dozen world localities, and the best and most famous examples of this rare sodium calcium strontium yttrium carbonate are from the famous locality at Mont Saint-Hilaire. This piece features a predominant, sharp, well-formed, layered pseudo-hexagonal crystal group on Albite matrix. The Donnayite-(Y) crystal measures 5 mm, and couldn't be sitting more aesthetically on the matrix. A beautiful crystallized example of this rare and desirable species in a lovely thumbnail sized specimen. Ex Paolo Matioli Collection.
