The sapphire – from cornflower blue to the color of lotus flowers

When you hear the name sapphire, the first thing that comes to mind is a deep blue
gemstone. In fact, sapphires are especially sought after when they have a vibrant, medium-
light blue hue without a gray veil, reminiscent of the beautiful look of cornflowers. In
addition, the gemstone is also available in almost all other colors, except for the color red.
 
That’s because sapphires and rubies both belong to the group of co-rounders, with the red
varieties referred to as rubies and all other colored ones as sapphires. Very exclusive is the
gemstone in the orangepink color of lotus flowers – in the technical language it is referred to with
the Indian word for this flower, Padparadscha. A characteristic feature of a sapphire is
pleochroism, which is expressed by the fact that the gemstone takes on different colors in
the eye of the beholder from different directions.
 
Thus, the appearance of a blue sapphire can vary between a pure shade of blue and a green-blue.

Sri Lanka and India – the sapphire and its most important deposits

Sri Lanka is known for the fact that sapphires have been found there since ancient times,
which stand out for their extremely beautiful blue-violet color.
 
A sapphire, in which a six- pointed star of light (asterism) can be seen or which reminds of the eye of a cat sparkling in the dark through a narrow light strip (Chatoyance), is a special feature that can also be found in Sri Lanka.
 
The sites of the highest quality of these gemstones in cornflower blue were located in the Indian region of Kashmir and even today the term Kashmir sapphire is synonymous with the highest quality. However, a sapphire originating from there is a rarity today, as the deposits have long been exploited.

The sapphire – its purity and cut

In general, a sapphire is considered high-quality if it has a high transparency, and thus
sparkles enchantingly. An exception, however, are clouded gemstones, in which unusual
optical effects such as chatoyance or asterisms occur.
The type of cut chosen in a sapphire depends essentially on the purity. Light-flooded and translucent gemstones are faceted to emphasize the brilliance, while a star sapphire is most beautifully accentuated on a smooth, outwardly curved surface.

Quality Factors

Colour
Especially the incidence of light plays a major role in the color or hue of a sapphire. Deviations of the blue sapphires range from colorless (i.e. white), yellow, green to an extraordinary orange or pink.
Purity
Purity also plays a role in the price. The most sought-after and therefore the most expensive is a
sapphire that is as transparent as possible with few inclusions.
Carat
1 carat (ct) corresponds to 0.2 grams – and indicates the weight of a gemstone. The higher the carat
number, the more valuable the sapphire. But it alone does not determine the value. Other factors
such as color, purity and cut play a major role.
Polish
For sapphires, the facet cut is mainly used, as this positively emphasizes the optical properties of the gemstone.
