All About topaz

All about topaz, one of the most mysterious stones. It is also the stone of the month of November ♦

It is the stone of the month of November (with citrine), but the topaz is also one of the gems coveted since antiquity. There is, however, a point against him: if it is blue shade is often confused with other stones less valuable, as aquamarine and apatite. Other times, the topaz is mistaken for smoky quartz or citrine. Care must be taken, therefore, because often a simple quartz is sold as topaz. And to say that the topaz can be just as precious as diamonds or sapphires.

The name. It’s called topaz for centuries. But what does the name? According to some, the term dates back to a small island in the Red Sea, Topazos. Here the Romans, according to this version, extracted the stones called, precisely, Topazos. Too bad, in real world they are not on topaz on island, but the stones are now classified as peridot. So much so that the island nowadays has changed its name: it is called Zabargad, which in Arabic means just peridot. The misunderstanding, however, is not solved. So? Another version traces the name topaz to Sanskrit, the classical language of ancient India. In Sanskrit, the word topas means fire. The mystery continues.

Characteristics. Sometimes the topaz has inclusions equivalents: according to experts, in some blue topaz you can have even the impression of a sort of floating. Attention: the color of the natural stone tends to fade in the sunlight. For this reason, a lot of topaz are treated. In some cases they are heated up to about 450 degrees celsius.

How to clean topaz. Topaz is ranked eighth on the Mohs scale, which measures the hardness of stones (in first place is the diamond ranked 10). Topaz, therefore, is a fairly hard and resistant stone. The greatest danger is that it will chip when hitting a harder material, or get scratched. But, as far as cleaning is concerned, it does not need special care. Just immerse the jewel for about ten minutes in a container with warm water and a couple of drops of liquid soap. Then, gently scrub with a soft-bristled toothbrush. Finally, it dries with a cloth.
