At Paris, an oval Chrysoprase, eight lines long and seven lines, broad, was- sold for three hundred and ten francs. The price generally has decreased of late, on account of the great quantity cut from the mines, which have recently been covered up, in order to raise its value again. At the royal palace of Potsdam, in Prussia, are two tables of Chrysoprase, the plates of which are three feet long, two feet broad, and two inches thick. CHRYSOLITE, PERIDOT, OLIVTN. The name of this stone is of Greek origin, and was well known to the ancients, although it is undecided whether they designated the same mineral by this name that we do at the present time, for they make it in their writings to be either the. topaz or goldstone, or the transparent gold-yellow stone. The chrysolite occurs in prismatic forms, generally a right prism with rectangular bases; also, in angular rounded crystalline grains or massive ; the fracture is conchoidal ; it is transparent and translucent', it possesses powerful double-refracting power; its lustre is vitreous and resinous ; the lateral planes of the crystals are sometimes striated ; the color is olive-green, turning to yellowish and brownish; it scratches glass indistinctly, and is attacked by topaz ; hardness, 6*5 ;
