Only in fine specimens in this mineral attractive as a gem, and its rarity  precludes its used ijn commercial jewelry. It is pleochroic and the absorption bands vary considerably according to direction.

There is band in the blue violet bands at 4600 A which is fairly strong in the 'beta' ray, and weaker bands at 5400 and 5030 A in the green and 4630 A in blue. There is another weak band at 4300 a in the violet. The bands are probably due to iron. The spectrum is not distinctive enough to form more than confirmative evidence of the identity of the mineral.

The list of absorption spectra shown by green stones could be extended still further, but all the most important and reliable 

instances have been given above. those translucent stone which occasionally shows band and are not mentioned above will be noted in the descriptive text later in the book where this is thought to be helpful.
