The Nature and Formation of Gemstones

Gemstones originate from a variety of organic sources. Most gems in the world—organic minerals, rocks, and crystals—form naturally underneath the Earth’s surface through a cycle of systemic metamorphosis. The required underground environment conditions for gem formation include several natural ingredients alongside the right temperature, pressure, space, and time.

For this reason, many gem deposits around the globe are located close to fault lines or other areas where tectonic plates interact to generate optimal heat intensity and high pressure. Besides the standard metamorphic, other gem formation processes include igneous, hydrothermal, and sedimentary.

Gem Information: The Factors Determining Value

After being mined from the Earth’s surface, geologists classify gemstones by their physical properties and unique characteristics. Invented by geologist Friedrich Moh in the 19th century, this system of classification is known as the Mohs scale of mineral hardness. Relative hardness and toughness (on a scale of 1-10, from softest to hardest) refer to a gemstone’s innate resistance to scratching or breaking.

When learning about gems, understand that gemstones are traditionally distinguished by their precious or semi-precious disposition. The four precious gemstones known to humankind are diamonds, sapphires, rubies, and emeralds. These precious gemstones have distinctive perceived value factors: they are translucent, extremely rare, and rated the hardest among others on the Mohs scale. All other gemstones are classified as semi-precious by default but have their own unique value.
