Depending on its manganese content, the intensity of its shade varies. Usually visible under the pink tint, its light will become stronger if the manganese concentration increases. Like most other silicates this stone is sensitive to temperature variations.

It is possible to vary its hue by making it much more vivid, simply by increasing the temperature. Its very particular color is associated with a femininity par excellence.
