Topaz Stones: Myths and Facts
This post is dedicated to the beautiful Blue Topaz stone. Before diving deeper into its meaning and characteristics, let’s take a closer look at a few key facts related to the gem. We are sure that any potential buyer or wearer is interested in finding out answers to questions like “what color is Topaz?” or “how resistant is it to scratches?”.
Topaz Stones: Key Facts
- Chemistry: the gem is chemically classified as a silicate mineral. It doesn’t occur abundantly, but it is spread worldwide in pegmatites, granite and metamorphic rocks such as quartzite. Topaz gems are also referred to as “prismatic crystals”.
- Hardness: Topaz is rated 8 on Mohs’s scale. This means it is resistant to abrasion, which makes it ideal for everyday use. This is the case for “pure”, rare Topaz and not for the common quartz Topaz which is graded 7.5.
- Color Spectrum: the stone occurs in a wide range of colors from white to yellow, pink, blue, green, and gray. The gem comes in reddish brown hues as well. As regards its diaphaneity and clarity, the stone is transparent to translucent. Note that blue and green hued Topaz can be easily mistaken for Aquamarine.
- Treatment & Cut: Most commonly, the gem occurs as a colorless crystal. What you are likely to buy from wholesale distributors is treated Topaz. Brown, pink, blue, and green hues can be obtained by irradiating clear crystals. This is a common heat treatment applied today. As regards cutting, the crystal has perfect cleavage in one direction. That is why carvings occur pretty rarely.
- Care: Although the gemstone is very resistant, it is recommended to use a soft cloth to clean Topaz jewelry.
- Occurrence and Notable Sources: clear Topaz crystals are massively found in Brazil. Other significant locations include the United States, Russia, Afghanistan, Japan, Mexico, Germany, Norway, Australia.
Popular Types of Topaz
Yellow, pink, and pink-orange gemstones are dubbed as Imperial Topaz stones. The pink variety is extremely rare. Many of these exemplars are treated to become brighter and more intensily colored. Be careful not to expose such gems to sunlight too much as they can fade.
Note: The American Golden Topaz is the largest cut yellow Topaz in the world. It weights 4.57 kg and is currently displayed in the National Museum of Natural History in Washington, D.C.
Orange Topaz, which is the primary birthstone for November, is the best-known Topaz. The orange variety is valued as a stone of success, prosperity, and abundance.
Blue Topaz is also very popular, but it does not occur in large amounts in nature. Typically, jewelry makers use irradiated, heat treated colorless Topaz to produce the much-desired blue gem items.
Mystic Topaz is a rainbow-hued gem. What you should note is that it is basically an artificially coated colorless Topaz. The rainbow effect is not a natural property of the crystal.
