Recently, the Matilda and Karl Pfeiffer Museum, of Piggott, acquired a new mineral specimen for their collection. The new acqisition is from the Yenbai Province of Vietnam, and is an example of pargasite within pure white marble.

"We purchaed this specimen by way of an online auction, and when it was delivered it turned out to be a bit bigger than we thought it was," noted MKPM trustee Don Roeder. "But, it's such a beautiful piece--and we didn't have anything in the collection from Vietnam."

The hefty sculpture was advertised to be from Luc Yen, although this is not as specific as it seems as several quarries which produce pargasite may be found in the area.

According to information from the auction catalog, the metamorphic process which gave rise to the pargasite is also responsible for transforming the host limestone into crystalline marble. This causes the mineral to exhibit visible cleavage plants, which give the piece a sparkling or "frosty" appearance.

The overall condition of the specimen is pristine, and it came with the custom base.

"We weren't able to attend the big gem and mineral show and sale in Tucson this year," Roeder offered. "But, this is a nice addition to the collection. We were just surprised it was so big."

Due to the larger-than-average size of the item, it is currently enjoying a spot on the mantel of the great room of the museum.
