Cultural History and

Significance of Jade

Ancient China: The Stone of Heaven


In ancient China, jade, known as "yu" (玉), was considered the "Stone of Heaven." It was more valued than gold or silver and symbolized purity, moral integrity, and immortality. Emperors were buried with jade suits, believing it would grant them immortality. Jade was used in various artifacts, from intricate carvings to ceremonial objects and jewelry.


Mesoamerica: The Jewel of the Gods


The Olmec, Maya, and Aztec civilizations of Mesoamerica also prized jade, associating it with life, fertility, and power. The Maya called jade "chalchihuitl" and used it in ritual objects, masks, and jewelry. Jade was so valued that it was often used in offerings to deities and as a marker of social status.


Maori Culture: A Symbol of Strength and Heritage


In Maori culture, jade, known as "pounamu," holds deep spiritual significance. It is considered a taonga (treasure) and is used to make tools, weapons, and ornaments. Each piece of pounamu carries a unique history and is often passed down through generations, symbolizing strength, authority, and connection to the ancestors.

Natural Jade vs. Treated Jade

Natural Jade


Natural jade is valued for its rarity and intrinsic beauty. It comes in two main types: jadeite and nephrite. Jadeite is typically more valuable due to its wider range of colors and translucency. Natural jade undergoes no enhancements other than cutting and polishing.


Treated Jade


Treated jade, on the other hand, undergoes various processes to improve its appearance. These treatments can enhance color, remove impurities, and stabilize the stone. While treated jade can still be beautiful, it is generally less valuable than natural jade.
