Jasper
ABOUT JASPER
About:Jasper is a unique and colorful variety of chalcedony, a microcrystalline form of quartz. Known for its diverse patterns and rich colors, jasper has been treasured throughout history for its beauty and utility. This guide provides an in-depth look at jasper’s characteristics, history, sources, uses, and significance.
Mining: Jasper is typically extracted through open-pit mining. The extraction process involves drilling, blasting, and removing the rock, which is then transported to processing facilities.
Processing: Extracted jasper is cleaned, cut, and polished to enhance its natural beauty. For use in jewelry and decorative objects, jasper is often cut into cabochons or shaped into beads.
CHARACTERISTICS
Color: Jasper can be found in virtually every color, with red, brown, yellow, and green being the most common. The color is primarily due to the presence of iron oxide and other mineral impurities.
Chemical Composition: Jasper has the same chemical composition as quartz, SiO₂ (silicon dioxide), but its opaque nature and unique patterns are due to the presence of impurities.
Density: Jasper has a density of about 2.5-2.9 g/cm³.
Crystal Structure: Jasper, like all chalcedonies, has a microcrystalline structure, meaning its crystals are too small to be seen without magnification.
Luster: Jasper has a vitreous to waxy luster when polished.
Hardness: Jasper has a Mohs hardness of 6.5 to 7, making it relatively hard and durable.
Transparency: Jasper is typically opaque, although some specimens can be slightly translucent around the edges.
