What are gemstones?

Most gemstones, like diamonds, are minerals. They are formed under high pressure, at high temperatures and at great depths.

Gemstones are very rare and therefore extremely sought after. Each gemstone is unique and impresses with its own individual beauty - thus gemstones are sought-after applications for individual and unique pieces of jewelry.

The gemstone and its characteristics

The study of gemstones is called gemology and involves the intensive analysis of gemstones of all kinds.
Gemstones that are used in jewelry are generally referred to as semi-precious stones or colored stones. People have been familiar with precious and semi-precious stones for 10,000 years. Gemstones are usually minerals, but can also be rocks, mineral aggregates or organic formations. Minerals, for example, can be formed in different ways - some crystallize from molten gases and melts in the earth's interior.
Gemstones meet three special criteria: rarity, transparency and a Mohs hardness of more than 7.
Accordingly, the diamond is also considered a gemstone, although it previously had no special significance for jewelry.
The weight of a gemstone is measured in international trade in carats , grains, mommes or grams.

However, the most relevant properties of a gemstone are its optical characteristics. These include color , shine, luminescence, fire, light refraction, transparency and fluorescence. Gemstones usually only reveal their full beauty when cut and polished.
A suitable cut not only gives the gemstone a certain shape, but also optimizes the light reflection and shine of the gemstone. The interplay of color, shine and play of colors makes most gemstones something very special. Inclusions are often not seen as "flaws" but as a unique feature of the respective gemstone.

What are jewels and what are colored stones?

In the broadest sense, every piece of jewelry is a jewel . In the narrower sense, however, only those pieces of jewelry made of high-quality precious metals that are set or decorated with one or more gemstones are called jewels. Cut gemstones without a setting are also often referred to as jewels.

Colored stones (today also "colored gemstones") are basically all gemstones - including non-colored ones - except diamonds. There are numerous different gemstones that are found in a wide variety of countries around the world. Discover the most well-known gemstones in our extensive RENÉSIM gemstone lexicon .

Real gemstones and their synthetic brothers

Increasingly sophisticated imitations of gemstones are a major problem these days and represent a (not always reputable) branch of industry that should not be underestimated. Imitations are not prohibited in principle, but must be identified as such. Unfortunately, with imitations, cheap stones are often offered as higher-quality gemstones at inflated prices. Differences are hardly noticeable to the layperson's eye. It often requires a complex authenticity test by experts to distinguish real gemstones from synthetic gemstones.

The religious significance of the gemstone

Gemstones can be found in most world religions.
In both Judaism and Christianity, certain objects have always been set with precious stones. In other major religions, too, precious stones are used to decorate buildings, statues or equipment.
Especially in Buddhism and Hinduism, numerous deities are depicted in precious metals and decorated with gemstones.

The gemstone as an investment

Of all gemstones, diamonds with a GIA certificate are the best investment. In some cases, special and rare rubies, sapphires, emeralds and a few rare colored gemstones are also suitable, but these only have an expert opinion from an independent certification institute.
