This
very fine, bright specimen consists of sharp, flattened, twined
octahedra with step faces, locally with second generation of tiny gold
crystals scattered on both sides. |
This
roughly square plate is composed of radiating fans of finely
reticulated dendritic elongate octahedral gold crystals. Tiny euhedral
quartz crystals are locally lodged among the gold crystals. |
This
unusual moderately abraded gold wire is fluted, indicating it is
composed of radically twined and elongated crystals. The thick "rams
horn" is formed in the same manner. The fish hook is from the Chibcha
Indians, circa 1540 |
This
slightly water worn spongy mass has negative casts after small quartz
crystals. |

This
reticulated cluster is composed of elongated and twinned crystals with
a brownish color reportedly due to a minor palladium content.
|
Pale
silvery yellow sharp twinned and slightly flattened cubo-octahedra to
5mm are without obvious re-entrant faces denoting a twin plane. |
This
piece is an exceptional combination of bright, complex, twinned
clusters of gold crystals. |
This
bright aggregate of flattened, twinned, octahedra to 9mm and crystal
plates is a superb example of material from this locality. |

An
aggregate of brilliant, arborescent, multiple-twinned flattened,
wirelike octahedral crystals on quartz. |
This
particularly spectacular specimen is composed of brilliant, pale

This
piece, from either the Winnemucca or adjoining Ten Mile District,
consists of a spongy mass of of small, arborescent plates and wire or
spicular crystals that have been etched from a large quartz matrix.
191.11 grams |
This
superb specimen consists of many spinel-twinned wires. |
This
exceptional, richly colored and slightly water-worn crystalline mass
has a 2.4cm edge on a flattened twinned octahedron. The piece was
mined in 1828 from the first gold mine in the United States.
34.9 grams. |
Tetrahexahedral Forms
Crystals top row left to right are twinned tetrahexahedral. Crystals
at top center and bottom center are untwinned tetrahexahedral. The
intergrown group at top right is composed entirely of tetrahexahedral
faces.

This
spectacular cube is slightly hopper formed. tapering down to a small
cluster of modified crystals. |
This
tabular composite cluster with cubic crystals on both sides
weighs 87.93 grams. |
These
elongated multiply twinned octahedra to 4.9cm form 5 out of 6 sections
of a complete 360 degree twinned crystal. The specimen weighs 54.93
grams. Attached to the twin are rounded and elongated incomplete
octrahedra, hoppered and ribbed. |
The
Fricot nugget (pronounced Free-co), weighing 13.8 pounds, is the
largest surviving crystalline gold nugget from the gold rush era. It
was found at a mine near Spanish Dry Diggin's on the American River in
1865. Thought to be lost for many years, it was re-discovered in a
safe deposit box in 1943. |

Ironstone's Crown Jewel |
|
One
form of gold found in California is gold in quartz which is
often hard-rock mined in vertical or horizontal shafts. This
contrasts with placer (loose gold, often nuggets) and fine gold
that has been recovered by hydraulic mining.
The gold specimen was unearthed at the Sonora Mining Co. mine in
Jamestown, California on December 24, 1992. Along with other
gold-heavy quartz pieces, the gold was first believed to be bits
of damaged machinery.
A number of days later, the materials were examined and found to
be full of gold. The “Crown Jewel” was the largest of the
pieces, weighing in at 60 lbs.
Word of the find first hit the press on December 31, 1992.
The find caused the Gold Trust and Reinsurance company of the
West Indies to make a $20 million offer for the Sonora Mining
Corp. of Toronto, Canada.
Many of the smaller specimens of crystalline gold were sold at a
Tucson, Arizona gem show.
In April 1993, the Sonora Mining Corp. offered the gold specimen
as a bond to Tuolumne County, California. The County ultimately
declined the offer.
Among those seeking to buy the specimen was the French
government.
After acquiring the gold-bearing rock, John Kautz, proprietor of
Ironstone Vineyards, had the sample etched with acid and most of
the rock removed by tweezers. This process took over a year.
What resulted is the specimen that has little original rock in
the upper part, and more original rock in the bottom part.
To display “Ironstone’s Crown Jewel,” Mr. Kautz had a
three-story building constructed at Ironstone Vineyards. The
upper story includes a vault to hold the gold specimen along
with the Jewelry Shoppe that sells items that include unusual
“gold in quartz” jewelry.
California Governor George Deukmejian opened the exhibit at
Ironstone Vineyards.
The specimen is available to be seen during normal Jewelry
Shoppe hours at no charge.
The name "Ironstone's Crown Jewel" comes from Kautz family usage
and promotional materials for the winery. It's the "crown jewel"
among the "jewels" of the historic Alhambra Theatre pipe organ,
the caverns, the extensive gardens, the historic gold mining
equipment, etc.
Ironstone's "Crown" Jewel, the 44 lb. crystalline gold specimen,
the world's largest. On display to the public at Ironstone
Vineyards, Murphys, CA
