Cobble Creek: 1 lb Quartz Points from Brazil
Each Quartz point ranges in size. Anywhere from 1/2" - 3" on average. Each pound will include anywhere from 10 - 15 points. These points are considered a commercial grade. Some points will have dings or chips or imperfections. Good for grids, crafts, wire wrapping, school projects, collecting and whatever you creative folks can think of that I certainly can not.
Each pound will be a random pull from our bulk supply.
Quartz is a mineral composed of silicon and oxygen atoms in a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar.
Quartz crystals are chiral, and exist in two forms, the normal α-quartz and the high-temperature β-quartz. The transformation from α-quartz to β-quartz takes place abruptly at 573 °C (846 K). Since the transformation is accompanied by a significant change in volume, it can easily induce fracturing of ceramics or rocks passing through this temperature limit.
There are many different varieties of quartz, several of which are semi-precious gemstones. Since antiquity, varieties of quartz have been the most commonly used minerals in the making of jewelry and hardstone carvings, especially in Eurasia.
