GEMS AND PRECIOUS STONES. .                              847
table-cut stone of 15.7 carats, measuring 16 by 13 millimeters, was of an exceptionally fine blue color. Another large stone, measuring 18 by 14 millimeters, weighed 14.2 carats. A smaller table-cut stone, 14 by 11 millimeters, weighing 10 carats, was of an exquisite pale-blue color. A large round cut stone, measuring 14 millimeters across and weighing 12.6 carats, was very brilliant and of fine color.
NORTH CAROLINA.
A beautiful beryl weighing 3 pounds and containing good gem material is reported by Mr. L. A. Gettys, of Shelby, N. C, to have been found in Burke County.
SOUTH CAROLINA.
About 10 pounds of pale blue beryl were obtained by Mr. J. M. McConnell, of Anderson, S. C, from a deposit 3 miles from Anderson. The broken crystals were found on the surface and yielded some cut gems.
CORUNDUM (SAPPHIRE).
Mr. J. M. Robertson, of Bozeman, Mont., reports that an oriental amethyst, as the purple sapphires are called, was found on a bar of Missouri River a few miles from Helena, Mont. When cut the stone weighed 3-1/2 carats. A green sapphire, or oriental emerald of a greenish-yellow color, clear and brilliant, 3 carats cut, was found with it.
The mines of the New Mine Sapphire Syndicate, of London, which
are situated in Fergus County, Mont., were operated only to a very
small extent and the output was less than in normal times. No new
mining operations were reported, the various dumps being washed
over.
DIAMOND.
ARKANSAS.
According to Kunz,1 32 stones were found by the watchman of the
Arkansas Diamond Co. in 1915. Theso stones were white, yellowish,
and brown. Three stones, transparent and perfect, weighed, respec-
tively, 0.32, 1.22, and 2.50 carats. The total weight of the stones
found was 17.9 carats.
The Kimberlite Diamond Mining & Washing Co. has been in constant
operation, according to Austin Q. Millar, washing ground from the
Kauney and the Ozark mines. It is the policy of this company to with-
hold figures of production, and the values given under the production
of diamonds are therefore too small. As soon as the company is in
a position to give figures of production, a more accurate statement
of the value of the diamonds produced in this country can be given.
The other companies in this field have not reported any production.
A detailed report of the diamond-bearing area is in preparation by
Hugh D. Miser, of the United States Geological Survey, who states
that according to reports at least 4,000 stones have been produced up
to July 1, 1916.
