As I have already mentioned
Titanite has more fire than diamond, more colors than any gemstone and
is rare to find it clean and of a light color. This latest limited
supply from Madagascar is very special and the gem featured below is
offered with a gem certificate.
When you buy your first piece of
Titanite just put it near a candle or artificial
light and be absolutely amazed! Titanite has a rather
unusual ability to take a beam of light and break it into all of the
spectral colors, so that it will change color depending on
the angle. Its dispersion,
(fire,) is one of the highest of all gem materials and is higher than
diamond. No collection of gemstones should be without a specimen of
Titanite.
This lovely heart
shape has all the factors above and is one of the best
examples of Titanite that can be obtained.
The best
paintings are like windows of light - as are the best gemstones. They
are seamlessly beautiful as are the purest colored gemstones. Titanite
is one of the best and recently some of the finest
quality African Titanite has come to the market. Buy early and buy best!
PLEASE NOTE: My movies and presentations are of the
actual gemstones...
the visuals are done both to test me and entertain you. If I
did
not embrace the challenge I most likely would not be selling
gemstones! Should you desire a copy of the video please email me.

These photographs
are extreme enlargements made by me under very bright
lights with a macro lens so you can observe the gem's clarity,
and of course, a magnification of any flaws. Monitors vary so I have
little control over the color on your screen only to say these
were made for a gamma corrected flat screen monitor with colors as
close as possible to the original.
All gems have been inspected
by a qualified gemologist and are guaranteed as natural. At Admiral
Cowdisley I am committed to top customer service, and quality material.
Email is encouraged with any questions. I will try to respond to email
within 24hrs.
TITANITE
Titanite has
a rather unusual ability to take a beam of light and break it into all
of the spectral colors. So that it will change color depending which
angle you are looking at it. Its dispersion, (fire,) is one of the
highest of all gem materials and is higher than diamond.
Titanite is
named from the Greek word for wedge, because of its typical wedge
shaped crystal habit. It is also alternatively called titanite for its
titanium content. Titanite can be cut as gems although it is
considered a rarity on the gem market. It brings to the table a fire
greater than diamond and unique color shades.Transparent specimens are
noted for their strong trichroism, the three colors presented being
dependent on body color.
Notable
occurances include Gilget, Pakistan; Mt Vesuvius, Italy; Kola Penn.,
Russia; Ontario, Canada and New York and California, USA.
What
of Titanite as jewelry? Like tanzanite it is a little bit
brittle. It is best as a pendant, necklace or earrings. And don't go
out and frame houses with it on. But as earrings and pendants (where
the light can react with it best anyway) you will have no problems.
Titanite is
the crystalline form of Titanium dioxide, also known as titanium(IV)
oxide or titania, is the naturally occurring oxide of titanium,
chemical formula TiO2. When used as a pigment, it is called titanium
white. It is noteworthy for its wide range of applications, from paint
to sunscreen to food coloring. Were the hydrogen collected, it could be
used as a fuel to produce electricity when in nanoparticle form.
Research suggests that by using these nanoparticles to form the pixels
of a screen, they generate electricity when transparent and under the
influence of light. If subjected to electricity on the other hand, the
nanoparticles blacken, forming the basic characteristics of a LCD
screen. According to creator Zoran Radivojevic, Nokia has already built
a functional 200-by-200-pixel monochromatic screen which is
energetically self-sufficient. No wonder Titanite glows as it does with
spectral color!

GIA
CLARITY GRADING USED BY COWDISLEY
Different gem labs grade
clarity in colored gemstones differently. Cowdisley uses the GIA
(Gemological Institute of America) Colored Gemstone Grading Scale.
According to the GIA – perhaps the world’s best known and trusted Gem
Association and Lab, there are THREE different charts for grading
colored gemstones (and Diamonds). Perhaps the one that most jewelers
are familiar with is the Type 1 Gemstone Chart, which includes the
grading of Diamonds. The Chart that a gemstone is graded in is
dependent on the physical characteristics of the majority of a
particular gemstone; such as Ruby being graded as a Type 2.. The charts
and the gemstones that fit into each are as follows:
|

clean. This includes gems such as Amethyst, Aquamarine, Blue
Topaz, Citrine, Kunzite, Tanzanite, Yellow Beryl, Yellow Chrysoberyl,
Diamond. |

Peridot, Quartz, Amethyst, Citrine, Ametrine, Spinel, Tourmaline,
Zircon. |

The
GIA nomenclature also specifies six levels of saturation ranging from
"grayish" (neutral grey) to "moderately strong" to "vivid." The term
"intensity" is also used to describe a stone's saturation.
Gemstone Saturation Chart

To
describe the darkness or lightness of a colored stone, the GIA system
has nine levels of tone ranging from "very very light" to "very very
dark." A numerical value is assigned to each label for use in a grading
report.
