Inclusions as a sign of its uniqueness
A Ruby is considered especially valuable if he is as transparent as possible. He has a few small inclusions, but not necessarily it as a blemish to see – such impurities are typical for a Ruby and a guarantee that it is a unique natural product.
The inclusions are either foreign minerals, cavities, growth-related irregularities or fine cracks. Since the 19th century, it is possible to create a Ruby also artificially – in this case the individual fingerprints of nature are missing.
Today, there are also gems on the market, which has been artificially enhanced Reinheit. The disadvantage, however, is that the result of this treatment is often not of long duration. For this reason you should sure to buy from a trusted dealer, who wants to sell you not incorrectly declared goods. The rubies, which we offer at RenéSim, are not guaranteed reinheitsverbessert.

When buying a Ruby, you should make sure in any case on a well-executed finish and in doubt prefer a smaller, beautiful sparkling gem opt for, as for a larger, which tarnished effect due to its unfavourable proportions.
The Ruby and its optical effects – the soft, silky, the Chatoyancy, and the Asterism
In some cases, inclusions in the form of rutile needles can create lovely Flächenschiller and light figures. For example, several right-oriented rutile needles in the Rubin are prerequisite for the occurrence of a silky shine. At many such inclusions a Chatoyancy arises (in French) ( chatoyant = dazzling), the cat’s eye effect is called. You is characterised by the fact that a narrow continuous light strip covers the surface of the Ruby.
In some cases, several such strips at the Ruby form the shape of a six-rayed star, what is known as Asterism.
All these figures of light is common, that they are highlighted the best of a cabochon cut.
