It must be understood, however, that NO ASSAYS, OR QUANTITATIVE DETERMINATIONS, WILL BE MADE. Samples should be in a lump form if possible, and marked plainly...

Seite 55 - Plate XIV. These have furnished some of the finest cut black rutile, which more closely approaches the black diamond in appearance than any other gem. Some of the lighter colored ones furnish gems strongly resembling common garnet. Beautiful long crystals at times transparent red, ranging from the thickness of a hair to $ and in some instances...
Seite xxiii - ... value, notably a few diamonds and occasionally a zircon or epidote; then in the development of the mica mines, some of which furnished some very beautiful beryls and others, garnets. Some of the garnet crystals of wonderful color and brilliancy were frequently found flattened between the plates of mica. The first systematic mining for gems was undertaken by Mr. CW Jenks, in 1871, when he opened the corundum mine, on Corundum Hill, near Franklin, Macon County. This proved interesting scientifically,...
Seite 30 - ... at Tessentee, on the creek of that name, in Smith Bridge Township, Macon County. Here a large vein of crystalline quartz occurs in an altered pegmatite. The development during the year was entirely in a kaolinized rock, in which the amethyst crystals, ranging from £ inch to 3 inches in length, were found loose with the quartz and mica in the kaolin. The entire vein was exposed to the depth of 20 feet by a landslide. It would appear that further working should disclose the amethysts in the rock....
Seite 26 - It is the breaking down of these veins that form many of the smaller often microscopic minerals found in the detritis of the gold veins. THE FELDSPARS. Several interesting varieties of feldspar occur in North Carolina, among which the following may be especially noted as the ones which are of importance as gem material. Orthoclase. — A very interesting variety of sunstone was found by JA D. Stephenson at the quarry in Statesville, NC; the reflections are as fine as those of the Norwegian, but the...
Seite 34 - frost-drift " is well illustrated by the conditions that prevail throughout this region. The unaltered rock appears at Stony Point at a depth of 26 feet and is unusually hard, especially the walls of the gem-bearing pockets. An exceptionally clear and reliable account of the search for minerals in Alexander County which resulted in the final uncovering of the important emerald and beryl deposits of Stony Point, has been given by the developer of the first emerald mine in this country, William E.
Seite 29 - Bath" (Pis. VI, A and VIII, A). A beautiful opalescent quartz has been found in Stokes County. Amethyst (Purple Variety of Quartz.) — An almost unique gem in the collection of the United States National Museum at Washington is a piece of amethyst found at Webster, NC, and deposited by Dr. HS Lucas. The present form is just such as would be made by a lapidary in roughly shaping a stone, preliminary to cutting and polishing it. It was turtle-shaped when found, though the shape was unfortunately destroyed...
Seite 46 - Also numerous isolated prismatic crystals up to 2\,z centimeters in length; many rather pale in color, but 3 crystals, presented by Mr. Hidden, in 1893, of a rich emerald-green. The yellow tinge exhibited by this mineral in even the darkest green gems will prevent it from competing with the emerald, since it is this very quality that has kept down the prices of the Siberian demantoids, or Uralian emeralds, as the green garnets are variously termed. The finest crystal of lithia emerald ever found...
