TOPAZ.
IDAHO.
White
topaz is reported to have been discovered by Mrs. Emma Mikesell at City
of Rocks, about 5 miles northeast of Moulton, Cassia County, Idaho. The
mineral is said to resemble diamond closely and has been cut into
stones of 1 to 3 carats. Some stones that have besn exhibited by the
owner of the claims are exceptionally clear and will cut glass like a
high-priced diamond. Miles E. North and C. C. Young, of Reno, Nev.,
propose to operate the properties.
TOURMALINE.
MAINE.
Mr.
Robert F. Bickford, Norway, Maine, reports that new pockets of
tourmaline were opened at the feldspar property on Mount Apatite owned
by the Greenlaw Corporation. One oblong emerald stone weighing 10-1/2
carats and several weighing more than 6 carats each were cut from the
material taken out. Some of the material is perfect and of fine color.
Other
minerals that have been found on this property are dark-pink
lepidolite, talclike altered pink and blue tourmaline, cookeite, and
other alteration products of original lithia minerals. A pink beryl
crystal was also discovered.
