 Most of the gems are precious stone found in Arizona are merely by products of the mining of other sub stances. and are sorted out from poor CT specimens The turquois, garnet and preidot are mined separately. There are several companies that have produced turquois in Arizona The garnets are gathered from the sand and gravel beds in which they are most commonly found.
 In preparing precious stones for market the best specimens are first selected. cleaned. cut in various shapes and polished. Poorer speci- mems are also cut and polished. or they may be reserved for use in pri- vate and public collections.
 Wholesale prices of gems-Tur- quoise is worth up to S1OO a pound at the mine, in the rough, but usually is less valuable Matrix material brings from S5 to S25 a pound. Cut matriX turquoise costs from ten cents to ten dollars a carat. Cut clear blue tur- quoise costs from S1 to s1O a carat, the price increasing with size When cut in large quantities. stones may be cut for three to five cents a carat.
 Garnet is sold in the rough as sin gle stones, and brings a price rather less than one-fifth the price of cut stone. Cut pyropene garnets are worth from 50 cents to S2 a carat, de pending on the quality Almandine garnets, if resembling the emerald, cost SIP to S15 carat. The cost of cutting is S1 to S150 per carat.
 Peridot is also sold as separate stones. Cut material runs from S2 to sl5 a carat; S usually buys a good stone. Cutting costs from $1 to $50 carat.
 Copper bearing stones, excluding high grade malachite, sell for about S10 pound. When cut they are sold by the stone rather than by carat. and are sold so as to make a profit. No definite price can be set They cost from five cents to ten cents carat for cutting.
 Chalcedony, unless of the turtle back variety, is hardly worth S1 per pound. Cut material is hardly worth the cost of cutting. which is to 10 cents a carat. Turtle back variety brings s5 or more for a stone.
 Amethystine quartz is almost val ueless except as mineral specimens unless if holds color The cut Ameri- can material is hardly worth more than the cost of cutting. But foreign material may be worth S4 a carat when cut The cost of cutting is from 90 cents to $1 9 carat.
 Topaz is bought by the single stone. Y me gem tTESlalS, when COlOfeu, nldN be worth $50 to $1OO Cut material, in dark blue shades, brings s1O to s25 a carat: the fine golden yellow bring s4 a carat; diamond cut white stones bring s1 to S2 a carat. The cost of cutting is about S1 a carat.
 In Arizona the turquoise and garnet are sure of a wide market, at almost all times. Gems of the copper group. azurite. malachite, dioptase, etc, will find a market, not always steady. but fairly so, especially with the curio seekers.
 Although there is, as has been seen quite wide variety of gems and pre- cious stones in Arizona, one could hardly say that prospects of any great or continued production are good. What production there is will probably always be on a small scale
