set
of these seams lies nearly flat in the rock. The ledge is fractured by
uncemented joints into large blocks. The most prominent set of these
joints has a northwest direction and is vertical.
That
the rose quartz will hold its color well for all gem purposes is shown
by the persistence of the rose color on the outcrop of this mineral
where it has been exposed to the weather for long periods. Other places
blasted into several years ago hold the same rich color on their
surfaces as within the mass of the rock. Rose quartz can be obtained in
quantity and in large blocks at this mine. It is reported that one
block was sawed into two table tops, measuring 18 by 30 inches. The
massive rose quartz is sold for from 3 to 25 cents per pound, according
to depth of color and number of flaws or seams. Selected material
brings from $8 to $12 per pound.
COLORADO.
Rose
quartz has been found at several localities in Colorado, especially in
Fremont County. One of the most promising of these is the Wild Rose
claim, located in May, 1907, by J. D. Endicott, of Canon City. The Wild
Rose claim is 6 miles north of Texas Creek and is located on a steep
mountain side about 500 feet above and one-third of a mile west of the
junction of Echo Canyon and East Gulch. The country rock is highly
crumpled cyanite-mica gneiss and schist, cut by hornblende schist beds.
The rose quartz occurs in a large mass or ledge that forms a part of a
pegmatite body. The pegmatite is also mica bearing, and may be mined
for this mineral at some time. The rose quartz outcrops for about 150
feet in a north and south direction along the mountain side. The
outcrop stands about 20 feet high, though the true thickness of the
mass could not be determined, as its dip was not known. Other smaller
masses or segregations of quartz occur through the pegmatite. The
greater part of the quartz of the pegmatite has at least a pale rose
color, though some is white. Portions have a deep enough color and are
clear enough to serve for gem purposes. Clear translucent to
transparent pieces of flawless rose quartz up to 2 inches in thickness
can be obtained, and also large blocks for ornamental purposes.
CALIFORNIA.
W.
D. Parson, of Freeman, Cal, reports the discovery of a deposit of rose
quartz of good color in Kern County. Much of the material near the
surface, at least, is more or less flawed, so that specimens of large
clear or translucent material are difficult to obtain. Mr. Freeman
states that the color of the quartz is good and that the quality will
probably improve on opening the deposit deeper.
RHODONITE.
CALIFORNIA.
J.
A. Edman, of Meadow Valley, Cal, reports a large amount of rhodonite
obtained from and around the Peters mine, near Taylors-ville, Indian
Valley, Plumas County, Cal. F. Stansfield, of the Jupiter Consolidated
Jewel Company, reports this rhodonite to be of fine pink or flesh color
marked with black lines. It is becoming popular for the same uses as
other opaque and matrix stones.
