Item Description

Neptunite and Benitoite are signature species from the famous Dallas Gem Mine. The highly lustrous, doubly terminated neptunite miniature has platy growth and desirable reddish-brown color accents. Most neptunites from here are lustrous jet-black. The bit of attached serpentine matrix and white natrolite are typical and fine accessories. Ex Kay Robertson Collection. Her number and label were lost during the move. Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record and the 50+ page article in the German Magazine "Mineralien Welt" November-December 2017). Excellent and colorful Dallas Gem Mine neptunite.
