Specimens of microcrystalline quartz are aggregates of microscopic crystals
Quartz crystals can be found in Pennsylvania at locations such as French Creek and the Reading Prong area. Look for areas with exposed bedrock or quartz veins where crystals may be present. Be sure to obtain permission from landowners before collecting specimens.
Most Quartz Crystals are worth as much as a grain of sand. Most sand is composed of minute crystals of Quartz. The make-up of Quartz is found in the Chemical formula of Silica or (silicon dioxide, SiO2). 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. So in truth, Quartz is one of the most plentiful substances on Earth!
Chalcedony
Bull quartz is a term used colloquially to refer to large, rough, uncut quartz crystals that resemble the horns of a bull. It does not have any special geological significance, but is simply a descriptive term used by collectors and miners to describe the appearance of certain quartz specimens.
Obsidian cools rapidly, preventing large crystals from forming. As a result, the mineral crystals are too small to be seen with the naked eye. The rapid cooling process hinders the growth of crystals, resulting in a smooth and glassy texture.
There are many varieties of quartz crystals that can be considered classifications beyond just five. Some of the names for the varieties are Macrocrystalline, Microcrystalline and Cryptocrystalline.
Microcrystalline quartz is created when silica-rich oozes deposited on the seafloor undergo recrystallization over time due to pressure and heat. This process results in the formation of small crystals within the sediment, giving rise to the microcrystalline structure of the quartz.
Flint, chert, and jasper are all microcrystalline forms of quartz, which means they are composed primarily of silicon dioxide. They are formed from the accumulation of tiny quartz crystals over time, giving them their compact and fine-grained appearance.

Quartz can appear in transparent hexagonal crystals.
No. It is very common and easy to find.
Obsidian cools rapidly, preventing large crystals from forming. As a result, the mineral crystals are too small to be seen with the naked eye. The rapid cooling process hinders the growth of crystals, resulting in a smooth and glassy texture.
The material used to manufacture piezoelectric crystals is quartz. Wrist-watch crystals are often made of quartz. Quartz is a transparent mineral. The statement "There are four quartz in an imperial gallon" is faulty, and logically meaningless.
