Just look at the movie below... in the dark with only a small flashlight three feet away... and you will understand the amazing qualities of good Titanite.
I purchased this large gemstone because of its phenomonal radiance and multitude of colors under lights. *THE RAINBOW FIRE* in all respects. Clean and brilliant yellow with the unusally strong flashes of red, green and blue this titanite has great radiance.
We know that 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 Pakistan is very special and the gems featured below is offered with a free gem certificate. |

PLEASE NOTE: Gemstones may have intrinsic value but they are very individual and not everyone likes everything. In fact that is a good thing! The same applies to paintings and fine wine. If I purchased a bottle of Chateau Mouton Rothschild Pauillac 1986 there is the remote possibility I might not like it and want a refund. Such is life so please don't hesitate to ask if you do not like any gemstone or painting you purchase from me.
My movies and presentations are of the actual gemstones.
Detail from my painting 'Venus Point' completes the presentation.

More and more color revealed.
Titanite has so much vibrancy it is difficult for the camera to focus
as the photo above demonstrates.
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.
SOME ELEMENTS OF MY GEM PHOTOGRAPHY EXPLAINED
|
 |
When photographing gemstones the elements of making a good painting should also apply. In other words the photograph must contain contrast, color and texture.
The first of these is the most important when trying to make any photograph or painting 'dramatic'. Contrast, or the differential between light and shade, is the first thing to try and obtain in any dramatic photograph. Imagine a picture with no contrast, a star in a daylight sky as opposed to lightning on a dark night. Now think of a gemstone where every facet is washed out with exactly the same shade of color.
What makes a gemstone sparkle and the color 'sing' is the contrast between the dark areas and light areas and the way the facets gather and reflect the light they capture. This is almost impossible to capture in a still photograph because sparkle is an 'active' element of a gemstone.All gemstones have what is called 'extinction' to some small or great degree.
|
 |
Extinct areas are areas where light is absorbed but not reflected or released and these areas can appear as either light or dark. The type and nature of the light can also affect the size and amount of extinction in a gemstone. The example of the zircon shown here opposite shows dark extinction top and bottom. This does not mean these areas remain 'static' as we all realize that as the gem moves so do the areas of extinction.
The second element to capture in the photograph is color or 'hue'. The purity of the color is what is most desired in a gemstone and if you can imagine the laser spark of pure blue from a sapphire reflected across a dark room you might have some idea of what contrast and pure hue combined can achieve. Of course ruby and sapphire are used scientifically to create laser beams.
The third element is texture and this I attribute to the cut of the gemstone when photographing. How the gem is positioned and how the lighting is arranged create the number and contrast within the facets. |

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:
| |
TYPE I
Usually eye clean
Aquamarine, Chrysoberyl, yellow and green, Heliodore, Morganite, Quartz, smoky, Spodumene, all Tanzanite, Tourmaline, green, Zircon, blue |
TYPE II
Usually included
Andalusite, Alexandrite, Ruby, Sapphire, all,Garnet, all Iolite, Peridot, Quartz, ametdyst, citrine, ametrine, Spinel, all, Tourmaline, all but green, red and watermelon, Zircon, all but blue |
TYPE III
Almost always included
Emerald, Red Beryl,Tourmaline: red and watermelon |
| VVS |
Minute inclusions, difficult to see under 10X. Eye clean. |
Minor inclusions, somewhat easy to see witd 10X. Usually eye clean. |
Noticeable inclusions under 10X. Usually eye clean. |
| VS |
Minor inclusions, somewhat easy to see witd 10X. Usually eye clean. |
Noticeable inclusions under 10X. May be eye visible. |
Obvious inclusions witd 10X. May be eye visible. |
| SI1 |
Easily noticeable witd 10X. Slightly visible to tde unaided eye. Usually low relief. |
Obvious inclusions, large or numerous under 10X. Apparent to unaided eye. |
Prominent to unaided eye. |
| SI2 |
Easily visible to tde unaided eye. Usually low relief. |
Obvious inclusions, large or numerous under 10X. Very apparent to unaided eye. |
Very prominent to unaided eye. |
| I1 |

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.
