Over the summer, I saw many beautiful stones made into a mala by my friend . I asked Rebecca if she could make me a particular color. And she did. This is the second mineral I’d like to share with you.
Purple Jade:
Jade actually is a stone consisting of two minerals, namely jadeite and nephrite. Nephrite is also a class of silicate minerals called actinolite that is made up of double-chained tetrahedra of silicate anions. Jadeite is another class of silicates that is characterized by single-chained silicate tetrahedras.
Again, silicates are minerals containing silicon (Si) and oxygen (O) atoms. In addition to Si and O, however, jadeite contains sodium (Na) and aluminum (Al) in its silicate structures while nephrite (actinolite) contains calcium (Ca) and magnesium (Mg). However, these minerals can also contain traces of chromium (Cr), iron (Fe), and Manganese (Mn), which are essentially responsible for their vivid colors.
The colors of both actinolite and jadeite can range from green, blue-green, purple, violet, to black. The purple color of purple jade stems from the presence of trace Mn ions in the actinolite.
