We prefer to do business the
good, old-fashioned way; but if paying by check or money order we may
require clearance of funds prior to shipment. We can take PayPal
payments, but are not set up for credit cards.
We do combine shipments
(or you may pick your stones up) and we can offer reduced prices on
multiple orders, depending on whose specimens are involved and how much
discretion we have. We prefer to ship by U.S. Mail (First Class,
Priority, or Parcel Post). For heavy items or lots, Flat Rate
Priority seems to be the best way to ship.
Prices mentioned include domestic shipping costs
by U. S. Mail. |

1: GEM MOUNTAIN, MONTANA
( ROCK CREEK ) (Sold) |
cc-5 |
|
|
|
|
This 3.35 carat clean gem crystal (from the Gem Mountain
property along Rock Creek between Hamilton and
Philipsburg) is doubly terminated and quite euhedral,
showing almost no evidence of water wear or
resorption. The yellow center in an otherwise
very pale green stone is also unusual. It may
be possible to cut the stone as a round so that it
appears yellow due to reflection of the center.
I would keep this one as a specimen, however.
It is natural and untreated - just the way it came
out of the ground! $510.00;
domestic shipment by insured mail included. |

2: GEM MOUNTAIN, MONTANA
( ROCK CREEK )
(Sold) |
cc-2 |
|
|
|
|
This somewhat
wafery stone weighing about 5.25 carats measures about 1/2"
across (unusually large for a Gem Mountain sapphire) and 3/32"
thick. Its body color is actually a little darker bluish
greenish yellowish (sometimes affectionately called "regurgitreuse"
in the trade). The dings around the edges appear to be
from glacial transport rather than clumsiness of the wash plant
operator. It is a textbook example of elevated triangles
on the basal pinacoid of a corundum crystal, and large enough to
show them very well. It is natural and untreated.
$200.00; domestic shipment by insured mail included. |

3: GEM MOUNTAIN, MONTANA
( ROCK CREEK )
(Sold) |
cc-50 |
|
|
|
|
This is a
fine gem sapphire crystal, which should produce one or two
rounds of fine medium blue or ice blue color, as indicated in
the photo taken down the C-axis on the left. The near
right photo is taken from the other end, and shows a little
silk, which seems to be confined near the surface and could be
avoided by placing the culet carefully. It weighs about
3.70 carats, and measures about 5/16" long by 7/32" in diameter.
It is natural and untreated. $600.00; domestic
shipment by insured mail included. |

4: GEM MOUNTAIN , MONTANA
( ROCK CREEK )
(Sold) |
cc-89 |
|
|
|
|
This heat
treated sapphire from Gem Mountain weighs 1.72 carats, and
because of its elongated habit it would cut three or four small
pale green rounds. It is about 3/8" long and 5/32" in
diameter. Its somewhat waxy surface is cue to the
cooking, which allows surface tension to "smooth over" some of
the surface growth or etching microfeatures.
$155; domestic shipment by insured mail included. |

5: NORTH CAROLINA
(Jacobs Mine, Cowee Valley)
(Returned to owner) |
rd-1-267 |
|
|
|
|
This tabular, gemmy Jacobs
Mine crystal weighs 2.67 carats, and is doubly
terminated (better than the pctures show). It
is somewhat wafery, and has a pearly luster. I
would not cab or facet it, but would keep it as a
superb mini-thumbnail crystal. It
is natural and untreated.
$675.00; domestic shipment by insured mail included
in price. |

6: NORTH CAROLINA
(Jacobs Mine, Cowee Valley)
(Returned to owner) |
rd-1-152 |
|
|
|
|
This 1.52 carat gem from
the Jacobs Mine is probably of the kind that made
George F. Kunz remark that only North Carolina had
pigeon-blood rubies as fine as the Burmese. In
sunlight, it is spectacular, even though it is not
as euhedral as some of the others. It is
tabular, slightly layered, and doubly terminated.
I might cut this one, but probably not. It
is natural and untreated.
$380.00; domestic shipment by insured mail included
in price. |

7: NORTH CAROLINA
(Jacobs Mine, Cowee Valley)
(Sold) |
rd-3-103 |
|
|
|
|
This one has all the attributes of the finest Jacobs
Mine crystals, except that it is not three feet
across. It's only 1.03 carats, but what a
lovely gem it is; with elevated
triangles on both terminal faces! If this one
does not sell quickly, I may buy it for our
collection. Let sunlight pass through
it, and see the transmitted light red and fluorescent blue of a fine Burmese ruby; but this
one is American! It is natural and
untreated. $300.00; domestic
shipment by insured mail included in price. |

8: NORTH CAROLINA
(Jacobs Mine, Cowee Valley)
(Sold) |
rd-3-123 |
|
|
|
|
This This doubly terminated 1.23 carat
crystal is a gem! It is not not water clear, but the body
color does not get better than this! It might be faceted,
but I would keep it as an example of the American ruby crystals
that Tiffany gemologist George F. Kunz likened to the finest
Burmese. It measures about 3/16" between parallel lateral
faces and about 1/8" thick (along the C-axis).
$350.00; domestic shipment by insured mail included in price. |

11: RUBY PLATE [VIET NAM]
(Returned to owner) |
ln-3 |
|
|
|
This platy specimen from Luc Yen
features an aftergrowth of gemmy, extremely saturated ruby on a base of semitranslucent blue, purple, and red corundum. It weighs about 35
grams and measures about 1-7/8 inches by 1-1/2 inches by 1/2 inch thick.
It is one of the finest of this habit that I have seen.

12: BADAKHSHAN, TAJIKISTAN SAPPHIRE
(Sold) |
aaj-1 |
|
|
|
This specimen is fist-sized
(3-1/2" wide by 3-1/4" high by2-1/2" deep) and is from "Viloyati
Mukhtori Gorno, Badakhshan, Pamir Mts., Tajikistan."
The main crystal of dark blue to white sapphire is
slightly over 2-1/2" long. It is not
terminated, and one can see the crystal is
transversely parted with matrix filling the gaps
between the sections. The matrix itself is
laced with numerous smaller elongated pyramidal
crystals of white to dark blue color (particularly
evident in the sawn base (far right image),
accentuated with small books of a light colored mica
(phlogopite or margarite?). Here and there you
can see linear sawmarks where the matrix was
attacked to expose the sapphire crystals.
$360.00; domestic shipment by insured mail included. |

13: BADAKHSHAN, TAJIKISTAN SAPPHIRE
(Sold) |
aaj-2 |
|
|
|
This is
another small fist specimen (3-1/2" wide by 1-3/4"
high by 3" deep) from "Viloyati Mukhtori Gorno, Badakhshan, Pamir
Mts., Tajikistan." The crystals are
not terminated, probably because they were naturally
parted and spaces between sections were filled with
matrix. This has a particularly large portion
of corundum, and it is impressive if not perfectly
preserved. $560.00; domestic
shipment by insured mail included. |

14: BADAKHSHAN, TAJIKISTAN SAPPHIRE
(Sold) |
aaj-3 |
|
|
|
This 2-3/8" long sapphire crystal is
well terminated on the top. but not on the bottom. It is
in matrix, mostly muscovite mica, measuring about 3" wide and 2"
deep. It would make a fine small cabinet specimen or
office paperweight (but lock it in your drawer over the
weekends). $560.00; domestic shipment by insured
mail included. |
