Varieties

Divided by color:

  • The most common colorless topaz (sometimes called white). Could be confused with diamonds. But topazes do not have the famous diamond shine.
  • Yellow . A lot of them. Color ranges from pale yellow to greenish.
  • Pink . They are not found often, but the price for topaz is moderate. Maybe because there is a synthetic analogue.
  • Blue . Also rare. There are several shades of color, Sky Blue is the most common.
  • Blue (dark blue). Commercial name "London". Looks like sapphire. The darker the shade, the more valuable the crystal.
  • Rainbow (mystic or nirvana topaz). An ordinary colorless crystal (sometimes it is not even topaz, but quartz or cubic zirconia). Only a special film is sprayed onto it, then it is “frozen”.

Bukanov writes: “Transparent crystals of topaz, covered with a white crust similar to tooth enamel, are called “horse teeth.”

Why does a stone lose its appearance?

The main reasons why a stone stops shining are bright sunlight and ordinary running water. Also, temperature changes contribute to the deterioration of the appearance of the mineral. It should be noted that London topaz should be especially protected from these factors, because its wonderful color is created artificially.

It is precisely because sunlight is destructive to topaz that it is recommended to wear jewelry with it in the evening. Owners often ask why the stone has become cloudy. The answer is simple: as a result of a sharp temperature change (for example, when leaving a warm car into a cold one), microscopic cracks can form in it, disrupting its structure, so it becomes cloudy.

By the way, ordinary running water, in which inexperienced people most often wash jewelry, is not harmless. It contains a number of chemical compounds and substances that negatively affect the condition of topaz.

What determines the price of a gem?

Several factors influence the cost. Here's how they rank in order of importance:

  • Color. The most popular are yellow, pink, and reddish crystals. There are few red specimens in nature, the demand and price for them are high.
  • Purity. Minerals of all colors, with the exception of colorless and blue, according to the classification of the purity of jewelry stones, are classified as type II.
  • Quality of cut. Crystals of natural origin are valued higher than refined ones.
  • Weight. Large topazes are common, so there is no need to talk about the effect of mass on cost. What makes them valuable is the combination of quality of polishing, color, and shape.

The most expensive crystals are red ones, priced from $300 to 1000. Pink ones cost from $100 to 500. Yellow ones are affordable for any budget - about $50. London blue is even cheaper - from $3 to $5.

No. 1 Color and density of topaz How and with what to wear the stone?

Topaz stone (photo) has the same properties and meaning regardless of the shade. And the stone has many shades and colors! What color is topaz, you ask, and you will get an answer - almost anything. Topaz of rich blue color, blue topaz, is popular. Transparent white topazes are found in nature, but are not popular in jewelry because they are more difficult and expensive to process than quartz, which costs much less.

What color is the topaz stone, which is considered expensive and high-status? This is a question you can easily hear in a jewelry store. Answer: golden topaz, or fancy- colored topaz (yellow on one side, blue on the other). Blue topaz stone, a photo of which is easiest to find on the Internet, is mined in many countries, but Brazilian topazes are called the most exquisite. The meaning of the blue topaz stone is to purify the owner’s thoughts, calm, and bring to life during times of stress. By the way, topaz loses color when exposed to direct sunlight and heat - take care of it in the summer! This is the only answer to the question whether topaz can change color.

Blue topaz stone (photo) properties and meaning - increased density, bright color, compatibility with silver, suitable for light eyes and hair. Yellow topaz is worn by those with brown eyes and dark hair.

Terminology

The natural ability of minerals to change their initial color is officially called differently:

  • The effect of pleochroism or simply pleochroism (multicolor). The ability of a mineral to change color when light is reflected in different directions. That is, when turning or from a different viewing angle, the color of the stone is different.
  • Alexandrite effect. Changes in the color of a mineral under different lighting (daytime, twilight or artificial). The second name is color reverse. Jewelers operate with it, implying the property of crystals to change color only under artificial light. Its depth is measured as a percentage: the greater, the more expensive the gem.

At the everyday level, any such stone is called a “chameleon”.

Only natural minerals have the listed properties, not synthetic ones.

No. 3 Precious or semi-precious Topaz What else do you need to know about the stone?

What does the topaz stone look like (photo), we have already gone broke, all that remains is to find out what its relationship is with other stones. Remember that topaz is dangerous for other semi-precious stones - it is denser than them, its edges are often sharper - they can easily scratch products with quartz, gold and silver. It doesn’t matter what color topaz comes in - the main thing is that you store it isolated from other stones. However, it is not scary for precious stones.

Topaz stone has calming and calming properties and meaning for humans. The same is true for the child. Moreover, since we are talking about a dense and bright stone, topaz is a good gift for a child over three years old. The decoration is easy to clean yourself with a sponge, napkin or soapy water on a brush. The child can handle this! By the way, blue topaz in silver has properties that are most suitable for school-age children. Give your child a topaz pendant or a keychain in the shape of a cartoon character with a small stone.

Be careful when buying topaz! Blue stone, whose name is topaz, is counterfeited using glass, cubic zirconia, or colored quartz. Ask the jewelry store to show the jewelry tag.

No. 2 The healing properties of topaz Properties of topaz stone for women and men

Topaz has extremely beneficial medicinal properties. In ancient times, the stone was called an assistant to entrepreneurs and scientists. It was believed that the stone taught one to focus attention, develop logic, concentrate on a subject, and also contributed to the development of imagination. What color of topaz, photos of which you will find in the “Rings with Topaz” section, can become a successful gift for a man? This is a delicate blue topaz in a massive silver ring.

The properties of blue topaz for women are assistance in bearing a child, normalization of sleep, topaz turns even very temperamental women into gentle guardians of the hearth. Give blue topaz to women in the form of a pendant that can be worn at heart level. Jewelry consultants are often asked why blue topaz changes color in this position. Astrologers attribute this to the fact that when worn, topaz transfers some of the energy to the owner. According to another version, the healing properties of topaz stone have nothing to do with it. Topaz changes color under the influence of temperature and ultraviolet rays. Just physics.

No. 4 Determining the authenticity of topaz What color are topazes and how to calculate them?

We have already discussed above what properties topaz has in silver and why topaz changes color. It's time to learn how to identify a stone among fakes and buy a genuine and status topaz. Topaz is easily recognized by its density (7 on the Mohs scale); it can scratch semi-precious stone or glass. Another way is to rub topaz on wool. Real topaz will become electrified and begin to attract light objects (paper, hairs).

If you have methylene iodide on hand and you get a topaz without a rim, check its authenticity by throwing it into a glass of liquid. Topaz (which means blue topaz stone, we figured it out in the first section) will go to the bottom of the container , the fake will float to the surface. By the way, you are safe if you like blue topaz - it is distributed all over the world and is relatively inexpensive, there is no point in counterfeiting it!

PS Is topaz a precious stone? No, just semi-precious. But it is affordable - you can delight yourself with jewelry with stones every day. Tell us in the comments why you are attracted to topaz, what you are used to wearing it with and who to give it to!

MORPHOLOGY


The crystals are common, usually rich in facets and often well formed. The crystal habit is rhombic-prismatic or meek-columnar. Sometimes large, crystals weighing up to 60-80 kg have been found. The faces of the prism are usually few in number, and the heads of the crystals are very varied and rich in faces; the faces of the prism often have rough vertical shading. Characteristic signs of natural dissolution appear on the heads of crystals in cone-shaped and nipple-shaped forms, and on the faces of prisms - in the form of negative tetragonal pyramids and grooves parallel to the elongation. Also parallel columnar coarse-crystalline intergrowths, cryptocrystalline “jasper-like” formations, radiant and thin-lamellar (pycnite) aggregates.

Methods for cleaning stones framed in silver

Cleaning topaz in a silver frame is not a complicated procedure at all, which you can easily do yourself without resorting to the services of specialists. You should not use detergents with silver-framed items, as they react chemically with silver and can cause irreparable damage to the mineral.

There are other options for cleaning such jewelry:

  1. First of all, you should wet the jewelry itself with cool water, then take a toothbrush marked “soft” and squeeze toothpaste onto it. Clean the frame and the mineral itself using circular movements for a short period of time. After this, you need to rinse the jewelry with water. During this process, it is worth reducing the contact of the product with water.
  2. In this cleaning option, we will need a small container filled with water at room temperature with the addition of a small amount of wine vinegar (literally a few drops, do not overdo it). Place the jewelry there. The cleaning period will be about half an hour. Then remove the jewelry from the solution and wipe it with a cloth. In the case of glued topaz, there is no need to immerse the product in the solution - just moisten a napkin and wipe the jewelry.
  3. And the last way. It is worth purchasing a special paste for such products. Such a substance is now in the public domain, and finding it will not be difficult. The only disadvantage of this product is its high cost. So the first two methods are the most affordable, and the result is the same.
