The origins of his name are some of the riddles: allegedly, shipwrecked pirate topaz found a legendary island in the ancient world and thus contributed to their name, because the Greek word "topazos" means "sought and found". On the other hand, we learn from Plinius the older one that this island was called "Topazos" and gave the stone its name, and according to another theory it is derived from the word "tapas", which is called "fire, The high refraction of light and the strong glaze of the stone.
Topas has been known for at least 2000 years. According to the revelation of John, he is one of the twelve stones in the gates to the city of God of the New Jerusalem, which symbolize beauty and splendor as well as repel enemies. In Germany, it gained importance through the topaz rock snail in the Vogtland, "Saxon diamond" was broken down in the 18th century for around 60 years. Schneckensteiner Topase decorate the Treasury of Elector Augustus the Strong and the English King's Crown.
Topas is a relatively frequent silicate mineral, which is often found in the accompaniment of beryll, tourmaline and apatite in magmatic rocks or in river sediments. The most important deposits are currently found in Brazil and Russia, and even the most imposing crystals come from there - the largest ever found crystal weighing 271 kg. Although topaz has the relatively high Mohs hardness 8, because of its high cleavage, it also requires a lot of skill during processing. The natural color spectrum of the topase ranges from colorless and yellow to various brown tones, to red and violet. Pink to reddish-orange varieties are most valuable. Their colors are obtained by varying the concentration of iron and chromium or, where these are not sufficient for a strong color, by irradiation or heating. This creates stones such as the dark green, brownish or violet shimmering Mystic-Fire-Topas and the light violet or pink Indian Summer-Topas.
Favorite among the topaz is currently the Blautopas with varieties like Swiss-Blue, Sky-Blue or London-Blue. Its fresh blue tones are reminiscent of the aquamarine, but it is more economical than the
Sea-blue beryl. Caution is advised with the trade names Gold, Palmeira, or Madeira Topaz, behind which are actually concealed citrines and yellow-burned amethysts.
If you want to make sure that you get a real topaz, you should look for stones called "Edeltopas". But our ancestors were not immune to confusion: the "Braganza diamond" used in the Portuguese crown in 1740 later turned out to be a particularly brilliant topaz.
