Pegmatite is a type of igneous rock that is characterized by its unique texture and mineral composition. It is known for its exceptionally large crystals and often contains valuable minerals and gemstones. Here are some key features and information about pegmatite:
Pegmatites are primarily composed of quartz, feldspar (especially potassium feldspar), and mica. These minerals are often found in exceptionally large crystals within pegmatite veins.
The most distinguishing feature of pegmatite is its coarse-grained texture. It contains crystals that are much larger than those found in typical igneous rocks. Crystals can range from a few centimeters to several meters in size.
Pegmatites are formed through the slow cooling of magma deep within the Earth's crust. The slow cooling allows for the growth of large crystals. Additionally, the composition of the magma and the presence of volatiles (such as water and gases) play a role in the formation of Pegmatites.
Pegmatites are known for their mineral diversity. They can contain a wide variety of minerals, including not only quartz, feldspar, and mica but also rare and valuable minerals such as tourmaline, beryl, garnet, and spodumene.
Because of their association with valuable minerals and gemstones, Pegmatites are often of interest to mineral collectors and gemstone enthusiasts. Some of the world's most famous gemstone deposits are associated with Pegmatites.
Kyanite is a typically blue aluminosilicate mineral, found in aluminium-rich metamorphic pegmatites and sedimentary rock. Kyanite is also known as disthene or cyanite.
Applications â??
Ceramic
Refractory industry
Foundry (Casting at high temperatures)
Emeralds are precious gemstones known for their rich green color, primarily composed of beryllium aluminum silicate (BeAlSiO) with traces of chromium and vanadium giving them their distinct hue.
Key Properties:
Color: Deep green to bluish-green
Hardness: 7.5-8 on the Mohs scale
Transparency: Transparent to opaque
Luster: Vitreous (glassy)
Formation: Found in hydrothermal veins and pegmatites, often in association with quartz and feldspar.
Common Applications:
Jewelry- Used in rings, necklaces, earrings, and bracelets as a luxury gemstone.
Collectors & Investments -High-quality emeralds are valuable and sought after as investment pieces.
Industrial Use - Synthetic emeralds are used in optical instruments and lasers.
Spiritual & Healing Beliefs - Some believe emeralds bring luck, wisdom, and emotional balance.
Product Grades:
Emeralds are graded based on color, clarity, cut, and carat weight (the "Four Cs"):
AAA Grade (Gem-Quality) -Deep green, high clarity, few inclusions, very valuable.
AA Grade - Slightly lighter green with minor inclusions, still premium quality.
A Grade â?? More visible inclusions, slightly lower saturation but still used in fine jewelry.
B/C Grade -Noticeable inclusions, lighter or uneven color, often used in lower-end jewelry.
Industrial Grade -Synthetic or heavily included stones, used in optical applications and lasers.
Price per Carat/Ton:
Emerald pricing varies significantly based on quality and origin:
Low-Quality (Industrial): $10â??$100 per carat
Mid-Quality (Commercial): $100-$1,000 per carat
High-Quality (Gem-Grade): $1,000-$100,000+ per carat (Colombian, Zambian, or Brazilian origin)
For bulk purchases (by ton), raw emerald ore or lower-grade material is priced differently, depending on clarity, color, and market demand. Would you like assistance in finding specific suppliers or current market rates?

Sillimanite, also called Fibrolite, is a colorless, or white glassy silicate mineral frequently found infibrous aggregates. It occurs in high-temperature regionally metamorphosed clay-rich rocks. It occurs with andalusite, kyanite, potassium feldspar, almandine, cordierite, biotite and quartz in schist, gneiss, hornfels and also rarely in pegmatites. It is an index mineral indicating high temperature but variable pressure. Sillimanite is used in the manufacture of high alumina refractories or 55-60% alumina bricks.

Potassium feldspar, also known as K-Feldspar, is a common type of feldspar mineral that is composed of potassium, aluminium, and silica. It is one of the most abundant minerals in the Earth's crust and is found in many types of rocks, including granite, gneiss, and pegmatite, that has a wide range of industrial and scientific applications. Its unique properties make it a valuable resource in a variety of fields, from manufacturing to geology. For example, it is a key ingredient in the manufacture of glass and ceramics, where it is used as a flux to lower the melting point of the materials. It is also used as filler in plastics, rubber, and other materials.
We, SRS Minerals are equipped to supply Good quality K-Feldspar, with Potassium content up to 12% in Lumps from 1-300mm size, and in powder form, if required.
