PRECIOUS STONES OF THE UNITED STATES.

To the recently distributed government report on the mineral resources of the United States for 1885.[[1]] Mr. G.F. Kunz contributes an interesting chapter in which is recorded the progress made during that year in the discovery and utilization of precious stones.

In the summer of 1885, a remarkably large pocket containing fine crystals of muscovite, with brilliant crystals of rutile implanted on them, was found at the Emerald and Hiddenite Mining Company's works, at Stony Point, N.C., and was sold in the form of cabinet specimens for $750. While the soil overlying the rock was being worked, nine crystals of emerald were found, all of which were doubly terminated, and measured from 1 inch to 3-1/8 inches in length and 1-2/3 inch in width. One of these crystals is very perfect as a specimen, being of a fine light green color, and weighing 8¾ ounces. It is held by the company at $1,500, and the nine crystals together at $3,000. Another of these crystals, doubly terminated, measures 2½ inches by 11/12 of an inch, and is filled with large rhombohedral cavities, which formerly contained dolomite. The only crystal from this collection that has been cut into a gem was found in a pocket at a depth of over 43 feet. In color it is of a pleasing light green, and it weighs 4-22/32 carats. No crystal of a finer color has as yet been found in the United States, and the gem is held by the company at $200.

During the recent mining, the largest fine crystal of lithia emerald ever found was also brought to light. It measures 2¾ inches by 3/5 of an inch by 1/3 of an inch. One end is of a very fine color, and would afford the largest gem of this mineral yet found, and one which would probably weigh 5½ carats. With this there was a number of superior crystals and some ounces of common pieces of the same mineral. The company estimates the value of this entire yield of hiddenite at about $2,500.

There was also found a quantity of quartz filled with white byssolite, forming very attractive specimens and valued at $250.

A number of beryls of a fine blue color, resembling the Mourne Mountain specimens, were found near Mount Antero, Chaffee County, Col. One of these was 4 inches long and 3/8 of an inch across, with cutting material in it. The other crystals measured from 1 to 1¼ inch in length, and from 1/5 to 1/3 inch in width.
