the.com/lazuli

The blue so precious it was ground up to paint the Virgin Mary's robe.

means A deep, vivid blue, properly 'lapis lazuli' — the rich azure of the semi-precious stone itself.

from From Medieval Latin 'lapis lazuli,' literally 'stone of azure.' The 'lapis' is just Latin for stone, but 'lazuli' traces back through Medieval Latin 'lazulum' to Arabic 'lāzaward,' borrowed in turn from Persian 'lāzhward' — the name of the place (and the stone) that gave the color its name. That Persian root is also the distant ancestor of our word 'azure,' making lazuli and azure old linguistic cousins both born from the same glowing blue rock.
