History of the Stone

The history of the topaz goes back to the ages. Scientists were divided in opinions as to the origin of the name of the stone.


So, according to one version, the word "topaz" came from the name of the island "Topazos"( now called "Zebirget"), located in the Red Sea. Confirmation of this version can be found in the works of Pliny the Elder, in particular, his "Natural History", where mention is made of a certain golden stone, mined on Topazose.

According to another version, the topaz received its name from the Sanskrit word "tapaz", which translates as "fire" and characterizes one of the most valuable varieties of stone.


Scientists and archaeologists find confirmation of the fact that topaz is known to mankind from ancient times.

So, during the excavation of one of the most ancient sites of primitive people in the Urals, nucleuses( manually processed pieces of stone) were found from topaz. Presumably, due to their high density, these stone plates were used by primitive people as a tool of labor.

After millennia, many people began to use topaz for making various jewelry and amulets. For example, the famous ancient decoration "Giselle's Gown", made of noble topaz, is dated to the 10th century.

The topaz is also mentioned in the Bible as one of the twelve stones that adorned the pectoral of Aaron the high priest.

Topaz was considered a stone that can help its owner to influence other people and expose secrets. It is not without reason that he was called the "stone of the court" or "the stone of psychologists".They were inlaid with their outfits and headdresses by the rulers of different countries. For example, a large yellow topaz adorned the famous "Cap of the Kazan kingdom," made in the 15th century on the orders of Ivan the Terrible in honor of the conquest of Kazan. Large topazes also adorned the imperial crown of Irina Godunova in the 16th century.

In Europe, the stone gained special popularity in the 15th century, during the heyday of the Renaissance and Baroque. The jewelers of Paris, Amsterdam, Idar-Oberstein and Alverpene learned to handle impeccably the topaz, giving it an unrivaled appearance. This opened a new page of the history of topaz in the number of the most popular gems.

The hardness of topaz on the Mohs scale reaches 8 units, and the density is 3.49-3.57 g / cm3.

The color of the topaz varies from blue to golden-yellow and pink-purple. True, in nature there are few topazes of saturated shades. Most often these stones have a muted color palette. In addition, the characteristic feature of topaz is its ability to lose color( discolour) under the action of direct sunlight, so very often topazes are ennobled to give them a rich color.

The change in the color of topaz is carried out by means of heat treatment and the effects of ionizing radiation. Usually two types of radiation are used to enhance the color of topaz: neutron and electron. Under the action of the electron gun, the topazes acquire a blue hue, and as a result of neutron irradiation a deep blue-blue color with a weak greenish outflow.

Each shade of topaz - natural or obtained by artificial means - has its name.

How to distinguish natural topaz from fake

To understand that you are holding a real topaz, you need to remember its main properties:

  1. Topaz has a low thermal conductivity, so if you touch the cheek with a stone, you will feel refreshing coolness.
  2. Natural topaz has no poisonous-bright shades. It is characterized by natural gentle tones.
  3. Topaz has a high hardness. If you hold the stone with quartz, there will be traces of quartz on the quartz, but not on topaz.
  4. If you rub the topaz woolen cloth, and then bring it to a small piece of thread or light paper, then the stone will pull these items to him.
  5. Topaz has a high density. Compare its weight with the weight of quartz of the same size - topaz should weigh more.
  6. Pink and yellow topaz have pleochroism, i.e.change their color when changing the direction of light. True, the topaz blue color of this feature is not observed.
  7. Natural samples most often have small defects: parallel cracks and rare inclusions.
  8. Topazes have the property of luminescing in ultraviolet rays( but only in the long-wave range).In this case, blue stones have a yellowish or greenish glow, and in pink topaz - orange-yellow.

Photos of topaz stone and products from it

Elena Vladimirovna

I usually clean products with topaz at home using warm water and a few drops of dishwashing detergent such as "Fairy".I give them to lie down in such a solution for about 15-20 minutes, and then gently rub it with a flannel cloth. And another of the jewelers suggested that it is very good to leave topaz for a night in saline solution, 1 tbsp.tablespoon of table salt per 1/2 cup of water. After that, the stone becomes brighter. But if you have a silver product without a rhodium coating, then this should not be done, silver quickly darkens.
