ULTRAMARINE
Ultramarine is the blue colour pigment obtained from ground-down lapis lazuli and has been a valued rock and pigment for thousands of years. Traditionally, lapis comes from Afganistan, but it is also found in Egypt and Chile, and, in smaller quantities, in parts of the former USSR & Asia. Its primary metaphysical property is as a bringer of peace.
Genuine lapis is very expensive, and as I only have lapis chips, my photo below is not wonderful. However, it gives you an idea of the ultramarine pigment, which is classified as a 'warm blue'. In painting, it is often used to symbolise royalty.
