Collection: Nephrite Jade Jewelry | The Mason-Kay Nephrite Jade Collection

Discover the Mason-Kay Nephrite Jade Collection, a stunning selection of fine green and black nephrite jade jewelry. Nephrite jade is the original jade of ancient China, treasured for thousands of years for its strength, symbolism, and beauty. As the tougher of the two true jades, nephrite offers exceptional durability, making it ideal for everyday wear. While white nephrite is historically prized, green nephrite—especially the earthy tones with a signature greasy luster—is gaining popularity in the United States. Mason-Kay sources high-quality green and black nephrite jade, including select translucent material from Siberia, offering a modern take on an ancient gem.
