Since
the appearance of the Synthetic Emerald on the market, many
consumers asked about the lighter material with bluish shade,
which may imitate the Columbian Emerald.
Now we have
it. Material comes in thinner (4-6 mm) and thicker (7 and up)
slabs without any sharp edges.
We believe
this material will become very popular at the jewelry market
in a very short time.

Hydrothermal Beryl with color of the best Paraiba Tourmaline. |

We produced the
most complete ever Gemological Kits of the Laboratory Grown Diamond
Imitations. They include 12 round 6.5 mm brilliants made
from:
- Flame Fusion Corundum
- Pulled Corundum
- YAG
- Flame Fusion Spinel
- CZ stabilized with Yttrium Oxide
- CZ stabilized with Calcium Oxide
- Hydrothermal Quartz
- GGG
- Rutile
- Strontium Titanite
- Lithium Tantalite
- Lithium Niobite |
|
Also,
the Kit contains small Moissanite crystal created by J.A. Lely technology.
We can put instead the Charles & Colvard Moissanite Cut Stone,
in size chosen upon your request for an additional cost. Also, the
Kit contains 2 empty jars which may be used for synthetic and natural
diamond stones in size chosen upon your request for an additional
cost. The price of the basic Kit is $220.00 plus $7.00 for the Priority
Mail shipment.

Synthetic
Rutile ("Titania")

The first laboratory
created Diamond simulant with the R.I. - 2.62 – 2.90, which was
superseded from the market by Cubic Zirconia. It is still the best
Diamond imitation with the most spectacular multicolor dispersion.
Now produced rarely.
The older well-known
Diamond simulant with R.I. – 2.41 and isotropic, same as Diamond.
It was a very popular Diamond imitation before CZ appearance on the
market. Now produced rarely.
At last, after
many years of absence on the market again this nice, really good in
color Ruby, which permits to cut unlimited in size stones.
New on the market
materials: a wide selection of multicolor flux grown Garnets: GGG
(gadolinium -gallium garnet), EGG (europium-gallium garnet), SGG (samarium-gallium
garnet) YIG (yttrium-iron garnet). The materials produced by one scientific
institute of physics in Siberia. These garnets come as small well-developed
crystals from 1-2 to 30-40 gr. They are growing for the microwaves'
technology and optical-magnetic needs. The main products grown by
the institute for these needs are the Ferro-garnets; other materials
were received relatively in the process of scientific research. Due
to magic-bright and dense colors, also high enough refraction indexes,
the cut stones from these materials would be tremendous, we expect.
The prices are $3.50/Car. if you buy up to 50 Car., $3.00/Car. for
50-100 Car., and $2.75 for quantities more then 100 Car.
Also 10% less for colorless GGG and black YIG.
Below you can see the list of these materials (shown the elements
effected the colors):
1.GGG colorless;
2.GGG red - pomegranate (Mn);
3.EGG lilac - amethyst (Nd);
4.EGG green - chrysolite (Cr);
5.GGG green - emerald (?);
6.GGG bluish-green - green zircon (?);
7.GGG blue - indigo (Co, Ti);
7a.GGG greenish blue (?)
8.GGG bicolor and tricolor crystals - red, green, blue, purple combinations
(?);
9.GGG red + blue, watermelon tourmaline alike (?);
10.EGG greenish-yellow - peridot (Co);
11.SGG yellow - yellow topaz (no additional metals);
12.SGG yellow - amber, brandy (Fe);
13.YIG black (no additional metals

Synthetic
Moissanite Gemological Samples
|
The
new material for gemologists, scientists and collectors - small crystals
of Moissanite (Silicon Carbide), growing by a new technology at one
scientific laboratory in Russia. We expect the appearance of same
crystals, big enough for industrial production of cut stones, in the
nearest future.
Here are some characteristics of these
crystals' types and prices:
1.Green and yellow hexagonal flat crystals,
4 - 8 mm wide, weight .25 - 1.20 Car. each. Price - $12.00/Car.
2.Green and yellow hexagonal plates, 5 - 10 mm wide, weight
.25 - .55 Car. each. Price - $10.00/Car.
3.Hexagonal well developed isometric green crystals (1 - 2
mm in all dimensions) and such crystals clusters (2 - 3 mm), weight
.05 - .20 Car. each. Price - $10.00/Car.
New
on the market laboratory created pulled Forsterite named TANZANION.
It is similar to Tanzanite both visually and in main physical properties,
but is more durable inhardness and is not as fragile.

According
to Mary L. Johnson and Shane F. McClure "…synthetic Forsterite far
more convincing as a Tanzanite simulant than any we have seen before."

Morion
Company carries Tanzanion rough materials, also cut stones of finest
quality. Because of biaxial optic character and strong pleochroism
the cut stones show violet, purple and blue colors.
Rough
Tanzanion sold at the following prices: purchase of less then
100 Car. - $5.50/Car.; 100-500 Car. - 4.50/Car.; 500
Car. and up - 3.75/Car.
The base price of the Tanzanion cut stones is $32.00/Carat.
The following quantity discounts are applicable:
$1,000
- $2,500 purchase 5%;
$2,500 - $5,000 purchase 10%;
