๐ Stone is a hard stone belonging to silicates; predominantly green in color, but also present in numerous other colors. It is not strictly a mineral, but rather an aggregate of jadeite and nephrite, two minerals distributed within the stone creating structures with fine granules and intertwined fibres.

โณ The name jade comes from the Spanish โ๐ฑ๐ช๐ฆ๐ฅ๐ณ๐ข ๐ฅ๐ฆ ๐ช๐ซ๐ข๐ฅ๐ขโ, which means โ๐ฑ๐ช๐ฆ๐ต๐ณ๐ข ๐ฅ๐ฆ๐ช ๐ง๐ช๐ข ๐ฏ๐ค๐ฉ๐ชโ, for its ancient use in the prevention and treatment of kidney pain.
The first extractions in China, where it was considered an "imperial gem", date back to 6000 BC for the creation of jewellery, interior decorative objects and tomb ornaments.
Even in Maori culture, jade, called "jade", is a sacred and precious material. Associated with concepts such as strength and longevity, stone has a profound spiritual meaning and is used to create cultural and traditional objects such as amulets and weapons, representing an integral part of Maori rites, myths and legends.
๐งช Jade develops in compact and fibrous masses, with a glassy shine.
Jadeite (๐๐๐๐ฅ๐๐ข๐๐๐) is mainly formed in igneous rocks through subduction processes. During the metamorphism of rocks rich in sodium and aluminum, high pressures and temperatures favor crystallization.
The formation of nephrite (๐๐๐(๐๐ ,๐
๐)๐[๐๐ข๐๐๐๐]๐(๐๐)๐) occurs through the metamorphism of rocks rich in calcium and magnesium minerals, under specific conditions of pressure and temperature. During formation, it can incorporate traces of other elements such as iron, chromium and manganese which affect its color.
Jade's distinctive green is often attributed to the presence of chromium and iron in the crystalline structure.
๐ The main jade deposits are found in China, Myanmar, Russia and Canada.
