Jade has been treasured for thousands of years, yet many are surprised to learn that “jade” refers to two dominant species: jadeite jade and nephrite. Nephrite is more abundant and typically shows a less saturated color and lower translucency than fine jadeite.

Jadeite, the rarer variety, is prized for its colors and translucency. The most coveted type, often called imperial jade, displays a rich, saturated green caused by trace amounts of chromium. Jadeite can also occur in yellow, reddish orange, white, black and purple.

Jadeite’s remarkable color range is one of the reasons it captivates collectors and gem lovers alike. Each color reflects subtle differences in trace elements and formation conditions, making jadeite both beautiful and geologically fascinating.
