|Benitoite / Neptunite Specimens
|Benitoite specimens and neptunite specimens are our specialty! We have a large stock of thumbnail, small,
medium, and large cabinet benitoite specimens. We have more benitoite specimens than neptunite
specimens because we find them at night using a shortwave blacklight and, ofcourse, neptunite specimens
don't glow in our shortwave U.V. lamps. Specimens with both benitoite and neptunite are less well stocked.
You can click on some of these images to enlarge them. I will be listing many more as I get time to process,
photo, and webpost them.
Most specimens here have been laboriously processed to expose their crystals and turn them into good
specimens. I have spent as much as 40 hours on some --even more on others. I prefer to process them by a
variety of mechanical means such as dremel tooling, chiseling, pressure washing, and media blasting--- but
wax and etch teknix usually demand their unfun participation in specimen development. They are all well
washed and ph balanced but may need an occassional washing to make them sparkle.
I try to price them fairly taking into account the market and time invested. With the closure of the Gem Mine
they are likely to diminish in already rare supply. The Gem Mine had a bad history of focusing on gem
extraction and often pulverized great specimens in that pursuit.
|The Sleeping Ben-Dragon. One of my favorite benitoite
specimens! This picture does little justice to this babe of a
benitoite specimen. Her "head" is a large, fairly blue, ben
crystal (1..6" x ~ 1.15" x ~1.25" x 1/2" thick) complete with
perfectly set "eyes", blonde "hair", and even a mouth and
tongue of mixed crossite/natrolite matrix.

|Five views of the largest and best benitoite crystal I've found in 22 years of mining. It
weighs in at an awesome 137 carats. It measures an astounding 1.50 inches on its sides and a beefy 1/2"
thick! The "Star" has mirror-like schistosity on every face.
I've heard there's a finer benitoite crystal specimen in the Mariposa Museum and I've seen two larger
steel gray "stars" (with major breaks); and there are a few smaller benitoite crystals(1.25") that are gem
grade beauties perched on matrix --- but I haven't seen any other "freefloating" benitoite crystals that
can match this one for size and beauty. I've decided to sell it for
Measures 18" long, 6" high, and 6 to 7" wide.
Peppered with gemmy benitoite crystals that
congregate in splotches. Well, see for
yourself--here's 2 photos you can click on. I
haven't weighed it yet-I'd guess 30 LBS--and I'm
still cleaning it. I'm authorized to sell it even as I
work on it and in this business thats fine by me.
Largest Benitoite Crystal I've ever
seen. Rare Arrowhead crystal form. Longest edge is
2.37". Opaque, very blue, high schistosity(it's shiny),
and has a small blob of neptunite and a few small
patches of natrolite attached to its show face. It
weighs 69 grams--thats 345 carats! It's a monster of a
benitoite crystal. It could be lapped into a garish
pendant stone--it has a good basic shape--though I'd
keep it as a specimen. Again, I 've been mining
benitoite almost 22 years and have never seen such a
huge crystal anywhere--not even in print. My partner
found it back when the Gem Mine was known as the
Dallas mine. I'm asking a modest $7,000. Item: WK7K
