Turquenite
Tuquenite (or turkenite , or sometimes spelled turcenite ) is a trade name given to a stone that is not a natural stone per se , but rather a howlite dyed to imitate turquoise.
Important details:
1. Origin:
-
Howlite is a naturally occurring, white to light gray mineral, often with dark veins.
-
Because howlite is porous, it readily absorbs dyes , making it an excellent candidate for being dyed blue and sold as an imitation of turquoise .
2. Why the name “tuquenite”?
-
This name visually and phonetically evokes turquoise , which can be misleading.
-
It is not a scientifically recognized term in mineralogy, but rather a commercial or marketing term used in jewelry and the semi-precious stone trade.

4. How to recognize tuquenite?

In summary:
Tuquenite is not a separate stone: it is white howlite dyed to resemble turquoise. It is used in inexpensive or decorative jewelry, but should not be confused with true turquoise, which is much rarer and more valuable.
