ruby & sapphire – these precious gemstones are the same mineral, corundum. when found as red corundum, it is called ruby. every other color, including blue, is called sapphire. it is the hardest mineral on earth, second to diamond. ruby is the birthstone for july and sapphire is the birthstone for september.
the ruby is a mine located in okanogan county, washington at an elevation of 1,201 feet. about the mrds data: all mine locations were obtained from the usgs mineral resources data system. the locations and other information in this database have not been verified for accuracy. it should be assumed that all mines are on private property.
the ruby is one of california’s best-known buried placer mines and is considered by many to be one of the largest producing river channel mines of modern times. it features a system of gold-bearing tertiary channels which have been reported to have
ruby, sapphire, and fancy sapphire. most people don't realize that ruby and sapphire are both gems of the mineral corundum.both of these gemstones have the same chemical composition and the same mineral structure. trace amounts of impurities determine if a gem corundum will be a brilliant red ruby or a beautiful blue sapphire.

calcite calcite is one of the main constituents of the ore veins and sub-veins in the country rock. small crystals lining cavities in the veins are common but good, larger calcite crystals are not common. very nice lavender-colored calcite crystals up to 45mm were recovered from the cross lake mine.
calcite belongs to the calcite group of minerals, a group of related carbonates that are isomorphous with one another. they are similar in many physical properties, and may partially or fully replace one another, forming a solid solution series.all members of the calcite group crystallize in the trigonal system, have perfect rhombohedral cleavage, and exhibit strong double refraction in
ruby is distinguished for its bright red color, being the most famed and fabled red gemstone. beside for its bright color, it is a most desirable gem due to its hardness, durability, luster, and rarity.transparent rubies of large sizes are even rarer than diamonds. ruby is the red variety of the mineral corundum. sapphire, the other gem variety of corundum, encompasses all colors of corundum
ruby, sapphire, and spinel. corundum and spinel are mingled in alluvial placers. mining is conducted on a small scale, from bai lai in the northeast of luc yen to the na ha area in the south, near the banks of thac ba lake. the most active sites are along the streams of cong troi, in nuoc ngap (an phu area).
on the edge of the system the veins contain dolomite and calcite with minor sphalerite, pyrite, and fluorite. massive copper sulfides are, in large part, restricted to former zones of massive pyrite. chalcopyrite, replacing earlier pyrite, is the dominant copper-iron sulfide but is in turn replaced by bornite and finally chalcocite-digenite.
sallot hole mine, calver (sk222743) beds of small purple fluorite cubes and larger clear crystals. sharp lustrous calcite crystals occasionally double terminated, marcasite. magpie mine, sheldon (sk175685) large sprays of light brown ‘dog-tooth’ calcite, sphalerite. the mine is now a field centre, for the peak district mines historical society.
mineralization was first noted about 1905. claims were located on the calcite-quartz vein at the bell mountain mine in 1914, followed by a decade of underground development of the vein. the mine produced in the 1920s. renewed exploration in the 1970s resulted in the discovery of a bulk-mineable deposit about 1980.

calcite is a trace mineral in precious metal-bearing quartz veins and a common replacement mineral in the surrounding intensely altered host rocks. late barren calcite veins crosscut the precious metal-bearing quartz-sulfide veins and were a significant source of dilution in the underground workings of the mine; where large, they also posed
classic gems like diamond, emerald, ruby or saphire are very hard, have no cleavage and gem grade material is clear and very expensive. on the other hand materials like jasper or agate are often just colorful hard stones produced in vast amount. rarelly also soft minerals like aragonite, calcite or fluorite are used in jewellery.
primary calcite veins: asset type: operating mine: mining methods: underground mine: for centuries, rubies have been revered as the king of gemstones with the power to restore youth and vitality. mentioned in the bible and in ancient sanskrit writings, rubies also symbolise love, passion, and power.
a few of them found gold veins along the streams, and underground mining began on several properties. gold-bearing quartz veins were found on reed's property, and underground mining began in 1831. north carolina was the leading gold-producing state until 1848 when the california gold rush began. production in north carolina gradually decreased
this red colored rock or vein is called rag-í-lál, or, the vein of rubies; the miners set to work upon this with much art, following all its ramifications through the parent rock. the first rubies that present themselves are small, and of bad colour: these the miners called piadehs (foot soldiers): further on some larger and of better colour
a word about photo quality: please note that many of the mineral photos were taken with older digital cameras, or else they were scanned with obsolete / low-res scanners.thus, some of the photos will look much more blocky / grainy / whatever than they might today. fluorescent mineral photography is also a special challenge for both film and digital; neither system was designed to handle the
mining techniques. historically epithermal gold has been mined by underground techniques as miners followed the narrow, twisting veins from the surface outcrops far underground. modern mining techniques mean that today most epithermal deposits are
the vein strikes northeastward, dips 85° se., and forms a stringer lode with a prominent outcrop some 1,800 feet long by 20 to 35 feet wide. the stringers, according to lausen, consist mainly of granular white quartz with platy calcite and, in places, glassy, yellowish
