Menilite
Opal O"pal, n. [L. opalus: cf. Gr. ?, Skr. upala a rock, stone, precious stone: cf. F. opale.] (Min.) A mineral consisting, like quartz, of silica, but inferior to quartz in hardness and specific gravity. [1913 Webster]

Note: The {precious opal} presents a peculiar play of colors of delicate tints, and is highly esteemed as a gem. One kind, with a varied play of color in a reddish ground, is called the {harlequin opal}. The {fire opal} has colors like the red and yellow of flame. {Common opal} has a milky appearance. {Menilite} is a brown impure variety, occurring in concretions at Menilmontant, near Paris. Other varieties are {cacholong}, {girasol}, {hyalite}, and {geyserite}. [1913 Webster]
