There are also, of course, much fancier items in the collection, including sharp floater crystals and twins of some truly rare species: senarmontite, glaucodot, stolzite, hambergite, neptunite
, epididymite, a petite cumengite "mace" on boleite, and (naturally) a superb specimen of a member of the whiteite group, specifically of whiteite-(CaFeMg).
A few issues later he offered well-formed benitoite and neptunite
crystals on natrolite for $1 to $2.
Rick Kennedy of Earth's Treasures (www.earthstreas.com) brought to Denver an excellent lot of neptunite
from the famous Benitoite Gem mine, San Benito County, California.
The first specimens of benitoite and neptunite
were found in 1907, and extensive tunneling took place for several years to extract benitoite gemstone rough.
The primary associated species, neptunite
and joaquinite, are attractive and highly desirable as well.
(2) Five fine matrix specimens of benitoite and neptunite
His pride and sense of accomplishment were deflated, however, when an older local collector named Harry Roberson walked in and purchased a very fine neptunite
and benitoite for $135.
Associated minerals are: microcline, aegirine, nepheline, magnesio-arfvedsonite, eudialyte, lorenzenite, lamprophyllite, catapleiite, titanite, vinogradovite, tundrite-(Ce), apatite, neptunite
, tsepinite-Na, kuzmenkoite-Zn, korobitsynite.
He was born in Geneva, Switzerland on January 14, 1938, and died in San Benito County, California on May 25, 2004, from injuries caused by falling rock while collecting benitoite and neptunite
. He lived his life to the fullest and died doing what he loved best.
(2) Associated with microcline, aegirine, nepheline, magnesioarfvedsonite, eudialyte, lorenzenite, lamprophyllite, catapleiite, titanite, vinogradovite, tundrite-(Ce), apatite, neptunite
, other labuntsovite group minerals and others.
There was a load of fine green crystallized dioptase from Tsumeb, which caused this year to be labeled the "Year of the Dioptase." Excellent neptunite
from California, choice anhydrite from Mexico as well as pink smithsonite, superb Los Lamentos wulfenites, rare Mexican creedite and even rarer paradamite were available for a price.
Bob Gill displayed a very impressive neptunite
specimen some 30 inches across from California's unique benitoite locality.
