    My understanding is that silicated chrysocolla is blue quartz. Rose
    quartz, amethyst quartz, adventurine quartz. 

    It is similar to three glasses of water, one with pink, one with
    purple, one with green food coloring..all are H2O, the food coloring
    does not change that each is H2O. 

    Lapis is composed of minerals where the blue is part of what makes
    lapis what it is. 

    Beryl can be green; emerald, blue; aquamarine, or yellow; heliodor.
    What makes it the color it is not part of what makes it chemically
    beryl.
