It is the most estimated quartz selection out there. Its most appreciated color is a lilac violet, but can be yellow as well as even transparent, depending upon the amount of iron it consists of. His hardness on the Mohs scale is 7. In spite of having actually gone down a ladder and be a semiprecious rock, due to its elegance and appeal deserves that, later on, we compose an exclusive post for her.
