Cobalt Blue
Celestial Blue Sapphire
Sapphire, the name has originated from Latin ‘sapphirus’ meaning blue and the Persian “safir’ signifying beloved of Saturn. That is it. Now what you will find, as you continue reading below, wouldn’t resemble the same monotony on this gemstone, which almost 90% of the online material would provide.
Apart from the same matter like blue and other types of colors found in this crystal, there is much more to provide to buyers. This includes information about color zoning, enhancements, or treatments, and imitations.
Pleochroism in corundum family, makes sapphire, a color zone prone stone. Color zone in this stone indicates towards the growth layers of mineral. It actually is in the form of series of concentric hexagons parallel to prismatic crystal faces. Like known, color and clarity of a gemstone, play a vital role in its pricing.
While valuing blue sapphire, a stone with a violet overtone, with no hints of grey or green, is preferred. As above, irregular color coverage, or dispersion is detracting from its value and beauty. A properly faceted stone can solve a stone’s color zoning problem and enhance its color coverage.
In addition, more color coverage ensures high saturation, seen in normal viewing positions. Sapphire gems cut too shallow can decrease color coverage.
As a precaution, sapphire shouldn’t be cut too shallow or deep, for that matter, since excessive deep-cutting is a sacrifice on brilliance.This creates black areas as ‘extinction’.
Whereas a shallow cut could result in appearance of short light paths called as ‘windows’. Therefore, most large sapphires are in oval, emerald or cushion cuts and the smaller ones are able to fancy other kind of shapes too.
There is rarely a sapphire which is flawless. Sapphires are usually found with inclusions. In addition, inclusions and clarity go together. Clarity is basically based on factors such as size, number, contrast, and location.
However, there are cases of sapphires with inclusions, which are relatively highly- valued just like flawless ones. Since sapphire is a hard stone, it does contain preferred directions of parting which shows, that material can be brittle in spite of its hardness.
Many internal conchoidal fractures and or cracks can weaken a stone. Nevertheless, there are very less chances when sapphire as a jewel has failed first, as compared to the metal work, during years of wear and tear.
Going back to clarity, it is decided by referring to its inclusions. Fracture filling is a common industry practice which includes oil, wax, paraffin, and glass and epoxy resin as fillers. After this, color of stone is still not diminished and fractures are non-reflective.
An enhancement like heat-treatment is also widely practiced. A permanent practice, heating facilitates melting of any silk inclusion plus intensified color. Whereas irradiation is a temporary process of intensifying color.
Numerous imitations or doublets are sold to travelers in Far East, since they are difficult to be separated from the natural sapphire gemstones. Even gemological tests, after setting in jewelry fail to catch the culprit.
Presence of misnomers, like ruby as red spinel and red garnet was prevalent during 1800’s. Still today, this malpractice is found to be conducted intentionally.
For example, a cobalt-blue glass is stuck with a crown of garnet, or a low-grade sapphire crown and pavilion are simply glued together with a colored epoxy. This results into a fake yet creation of a blue sapphire with an expensive hue reflection.
