Physical properties
Hardness: 6.5–7.0 (Mohs scale); Color: Lavender, pale violet, or lilac; Luster: Vitreous to greasy; Crystal Structure: Monoclinic; Cleavage: Prismatic in two directions at 87 and 93 degrees; Specific Gravity: 3.25 to 3.35.
Formation & geological history
Formed under high-pressure, low-temperature conditions in subduction zones within metamorphic rocks. Usually found in serpentinites. Geological age varies, but major deposits range from the Mesozoic to Cenozoic eras.
Uses & applications
Primary use is in jewelry (beads, cabochons, bangles) and ornamental carvings. It is a highly prized decorative gemstone and 'stone of virtue' in various cultures.
Geological facts
Lavender jade is rarer than green jadeite. The purple hue is typically caused by the presence of manganese or iron impurities replacing aluminum in the crystal lattice. Most high-quality lavender jadeite comes from Myanmar.
Field identification & locations
Identify by its high density (feels heavy for its size) and cold touch. In the field, look for a 'felted' or interlocking fibrous texture. Found primarily in Myanmar, Guatemala, Russia, and Japan. Collectors should watch for 'Type C' jade, which is dyed to mimic this color.
