Gemstones Dealers in Mia, Alwar

Our exclusive range of quartz is available in various colors but our milky quartz is famous for its unique milky white color. Apart from this, our productive range of wholesale green quartz is also appreciated and can be availed as per the desired specifications of our esteemed clients. Moreover, we are known amongst the prime quartz manufacturers in India. Crystal Habit Quartz belongs to the rhombohedral crystal system The ideal crystal shape is a six-sided prism terminating with six-sided pyramids at each end. In nature quartz crystals are often twinned, distorted, or so intergrown with adjacent crystals of quartz or other minerals as to only show part of this shape, or to lack obvious crystal faces altogether and appear massive. Well-formed crystals typically form in a 'bed' that has unconstrained growth into a void, but because the crystals must be attached at the other end to a matrix, only one termination pyramid is present. A quartz geode is such a situation where the void is approximately spherical in shape, lined with a bed of crystals pointing inward. Varieties Pure quartz is colorless or white; colored varieties include rose quartz, amethyst, smoky quartz, milky quartz, and others. Quartz goes by an array of different names. The most important distinction between types of quartz is that of macrocrystalline (individual crystals visible to the unaided eye) and the microcrystalline or cryptocrystalline varieties (aggregates of crystals visible only under high magnification). Chalcedony is a generic term for cryptocrystalline quartz. The cryptocrystalline varieties are either translucent or mostly opaque, while the transparent varieties tend to be macrocrystalline. Although many of the varietal names historically arose from the color of the mineral, current scientific naming schemes refer primarily to the microstructure of the mineral. Color is a secondary identifier for the cryptocrystalline minerals, although it is a primary identifier for the macrocrystalline varieties. This does not always hold true. Major Varieties Chalcedony : Any cryptocrystalline quartz, although generally only used for white or lightly colored material. Otherwise more specific names are used. Agate Multi-colored, banded chalcedony, semi-translucent to translucent. Onyx Agate where the bands are straight, parallel and consistent in size. Jasper Opaque chalcedony, typically red to brown Aventurine Translucent chalcedony with small inclusions (usually mica) that shimmer. Rock Crystal Fibrous gold to red-brown coloured quartz, exhibiting chatoyancy. Amethyst Clear & Colorless Citrine Purple & Transparent Prasiolite Yellow to reddish orange to brown, greenish yellow Rose Quartz Mint green & Transparent Rutilated Quartz Pink, translucent, may display diasterism Milk Quartz Contains acicular (needles) inclusions of rutile Smok Quartz White, translucent to opaque, may display diasterism Morion Brown to grey, opaque Carnelian Dark-brown & Opaque Synthetic & Artificial Treatments A synthetic quartz crystal grown by the hydrothermal method, about 19 cm long and weights about 127 grams Not all varieties of quartz are naturally occurring. Prasiolite, an olive colored material, is produced by heat treatment; natural prasiolite has also been observed in Lower Silesia in Poland. Although citrine occurs naturally, the majority is the result of heat-treated amethyst. Carnelian is widely heat-treated to deepen its color. Due to natural quartz being so often twinned, much of the quartz used in industry is synthesized. Large, flawless and untwinned crystals are produced in an autoclave via the hydrothermal process; emeralds are also synthesized in this fashion. While these are still commonly referred to as quartz, the correct term for this material is silicon dioxide. Occurrence Quartz occurs in hydrothermal veins and pegmatites. Well-formed crystals may reach several meters in length and weigh hundreds of kilograms. These veins may bear precious metals such as gold or silver, and form the quartz ores sought in mining Erosion of pegmatites may reveal expansive pockets of crystals, known as "cathedrals." Quartz is a common constituent of granite, sandstone, limestone, and many other igneous,sedimentry, and metamorphic rocks
