What is the difference between nephrite and jadeite?

Nephrite and jadeite are two distinct mineral species that both fall under the broad category of jade. Nephrite is an amphibole with a fibrous structure making it exceptionally tough, while jadeite is a pyroxene that often displays brighter translucency. Historically, older Asian carvings tend to be nephrite, whereas brighter green varieties appearing in later periods are frequently jadeite.

How do I care for antique jade?

Antique jade is physically resilient due to the hardness of the stone, but it benefits from gentle handling and storage away from harder gemstones that might scratch mounts or details. Clean the stone simply with warm water and a soft cloth, avoiding harsh chemical detergents. If the piece includes precious metal mounts or organic elements like mother-of-pearl, tailor the cleaning method to protect the most vulnerable material.

How can I tell the period of a jade carving?

Dating relies on stylistic clues, subject matter, and the nature of the tool marks left on the stone. Qing Dynasty pieces often display intricate traditional motifs and specific ritual forms, whereas Republic Period items frequently adopt distinct stylistic shifts. Associated elements like silver or gold mounts, as well as fitted hardwood stands, also provide valuable chronological context for pieces from the nineteenth and early twentieth centuries.
