vääriskivi

A vääriskivi, translated to English as gemstone or precious stone, refers to a mineral or organic material that is prized for its beauty, rarity, and durability. These materials are typically cut and polished for use in jewelry and other adornments. The value of a vääriskivi is determined by several factors, including its color, clarity, cut, and carat weight.

Gemstones are broadly categorized into precious and semi-precious varieties. Traditionally, the precious gemstones are diamond, ruby, sapphire, and emerald. All other gemstones are considered semi-precious. However, this distinction is largely historical, and many semi-precious stones, such as alexandrite and tanzanite, can be rarer and more valuable than some precious stones.

The geological conditions under which gemstones form contribute to their rarity. Many are found in specific geological environments, such as igneous or metamorphic rocks, or in alluvial deposits. The process of extraction and refinement also plays a significant role in their cost and availability.

Beyond their use in jewelry, gemstones have also held symbolic and cultural significance throughout history. They have been associated with astrological meanings, healing properties, and status symbols. The study and identification of gemstones fall under the field of gemology.
