- Neptunite on Natrolite
- Thumbnail, 2.4 x 2.4 x 1.6 cm
- Dallas Gem Mine, San Benito Co., California
- Ex. Ron Pellar
A sharp, extremely well-balanced neptunite thumbnail with the best black neptunite (luster, sharpness!), perched smartly on stark white natrolite matrix. Now, such pieces are hard to come by in this quality and the deposit is basically exhausted for such things. Ex. Ron Pellar thumbnail collection. Joe Budd photos.
