Often also written Safir in German.

The line between pink sapphire and ruby ​​is not defined, which used to lead to heated discussions. The trade tended to refer to intensely pink stones as rubies, as this justified a higher price.

Today this discussion is obsolete, as the pink sapphire has continuously gained in popularity and thus in value. We at the Wiener Edelstein Zentrum have always been of the opinion that it is better to own a pink sapphire of really finer color than a ruby ​​of a somewhat dubious (because it is too light) color.

Origin of name: from the Greek σάπφειρος sappheiros, which in turn is derived from the Hebrew ספיר cappiyr. This word was used to describe blue stones such as the sapphire but also the lapis lazuli.

Synonyms and trade names: no

Possible confusion: with other pink gemstones, syntheses and glass.

The number of pink gemstones or gemstones that also occur in pink is relatively high. The most important are tourmaline, spinel, beryl (morganite), topaz, spodumene (kunzite) and diamond. Some garnets, especially rhodolite garnets, are occasionally pink.

Identification is based on optical and physical properties such as refractive index, birefringence, specific gravity and absorption spectrum and is usually not a major problem for a person skilled in the art.

Differentiation from syntheses:

The most common are so-called Verneuil sapphires. The process, which was patented in 1902, has been producing very cheap sapphire syntheses in mass production since 1904.

The frequently heard customer objection that the stone has been in the family for a century is therefore no indication of authenticity.

Verneuil sapphires are usually easy to spot for those skilled in the art. Unlike Verneuil rubies, Verneuil sapphires almost always contain telltale gas bubbles and curved streaks of growth.

With all other synthetic sapphires that are grown with very complex and expensive methods, a magnifying glass and experience are often not enough for identification. In most cases, careful study of the inclusions leads to success, but stones are very rarely found where modern high technology, e.g. element analysis by means of X-ray diffraction, Raman spectroscopy, or the like has to be used.

The good news: most syntheses are cheap Verneuil sapphires. High-quality, not so easily recognizable pink syntheses are significantly rarer than, for example, high-quality ruby ​​syntheses.

In addition, the risk of falling for a high-quality ruby ​​or sapphire synthesis has decreased significantly in recent years. Due to the enormous costs and probably a lack of economic success, a number of manufacturers have stopped production or operations.

Occurrence: the most important occurrences are in Africa (Tanzania, Madagascar, Malawi) and in Asia (Sri Lanka, Burma, Vietnam).

processing: sapphires are usually very easy to process due to their extremely high hardness and the lack of cleavability.
However, sapphires should not be used in the fire. On the one hand, because color changes can occur at higher temperatures, on the other hand, because corundum usually contains liquid and mineral inclusions, which have higher coefficients of expansion than the host crystal. When heated, these inclusions expand more, which can lead to cracking or even destruction.
