If you are searching for a gemstone with a unique and alluring appearance, Andalusite should be on your list. This beautiful gemstone has brilliant pleochroism that displays marvelous olive green and brick red colors. What makes it even more special is that it combines two minerals, Kyanite and Sillimanite, to form this elegant mineral used in making jewelry.
Nature and Appearance of Andalusite
Andalusite is a strongly pleochroic gemstone that ranges in hardness from 7 to 7.5. Its interesting tone and remarkable durability make it an attractive choice for most jewelry lovers. Although abundant in nature, its crystals are often transparent. Most of the gemstones are mined in Brazil and found in stream beds or hillsides embedded in clay. They are also discovered in some areas of Australia, South Africa, Sri Lanka, and the Inyo Mountains in California, USA.
This unique gemstone reflects shades of yellow, olive-green, and reddish-brown colors within a single gemstone. The colors vary depending on the viewing angle and how it has been cut. Some can display multiple colors even at a single viewing angle. These colorful gems are important in creating Andalusite jewelry items like rings and pendants.
Varieties of Andalusite
Andalusite is a gemstone with various versions that come in different colors and appearances. These versions include:
1. The Andalusite Chiastolite gem
This unique version contains a cross pattern in the interior cross-section of the crystal giving it an unparalleled look.
2. Viridine Andalusite
The Viridine Andalusite contains a distinctive bright green to an olive-green color that is quite alluring.
3. Cat’s Eye Andalusite
This variety is characterized by the effect in cabochons or dome-shaped Andalusite created by a fibrous inclusion.
How Special is the Andalusite Gemstone?
Andalusite is an incredibly rare and valuable gem with a history of mistaken identity. Since centuries, it has been collected as a Talisman that has a special ability to turn into different forms. The movement of colors is what makes this gemstone unique. The gem contains a crystal structure that makes it change color when turned from side to side.
Larger sizes of the gemstones are very rare. Nevertheless, they contain durability and extreme value that makes them a favorite gem for jewelry, especially men’s jewelry due to its masculine appeal.
Andalusite has a unique feature where, when Kyanite, one of the components of Andalusite, is subjected to higher temperatures and pressure, it turns into Sillimanite. Glamorously, Andalusite can withstand extremely high temperatures without developing a change in its structure. This feature has made it possible for it to be used in making some spark plugs and furnaces.
Importance of Andalusite Gemstone
Apart from just making jewelry, Andalusite has several other crucial uses. It is believed to be a remedy for sending away evil spirits or simply turning bad luck into good luck. It is thought of as a stress reliever and aid against depression. Regulating sleep and helping relieve paralysis in nerves, muscles, and joints are also attributes credited to the gemstone. Wearing the crystal is also believed to reduce fevers, arthritis pain, and joint inflammation.
Distinguishing Features of The Gem Quality
With a wide range of stones available in the market, distinguishing premium quality stone from an average one can be difficult. However, there are several criteria you can use to identify a high-quality Andalusite gemstone.
Andalusite often contains tiny needle-like features, but as long as they do not have pleochroism, they are good to go.
2. Carat Weight
Bigger gems cost more than smaller ones. Brazilian gems contain more carats hence being more expensive.
3. Cutting of the Gemstone
Poorly cut Andalusite is dull and fails to reflect color play, therefore having a lower value.
In conclusion, it’s essential to be aware of lab-created gemstones since there are various gems in the market; therefore, getting the exact cut details before purchasing an Andalusite gem is crucial. Be careful not to fall for lower-priced gems that could be fake or of low quality. Andalusite gemstone is unique due to its ability to display different colors and withstand very high temperatures, making it highly desirable to both jewelry makers and collectors.
