Physical properties

Jadeite center: Hardness 6.5-7, Apple green, Greasy/Vitreous luster, Monoclinic. Accent stones include Red Ruby (Hardness 9), Blue Sapphire (Hardness 9), and Green Emerald (Hardness 7.5-8).

Formation & geological history

Metamorphic formation under high pressure and low temperature conditions. Primary source for high-quality Jadeite is Myanmar (Burma), formed millions of years ago in subduction zones.

Uses & applications

Exclusively used in high-end jewelry, decorative carvings, and as a cultural status symbol in East Asian traditions.

Geological facts

Jadeite is one of two minerals known as Jade (the other being Nephrite). The 'Imperial Green' variety is rarer and more valuable than most diamonds of equal weight. Rubies and Sapphires are both varieties of the mineral Corundum, differing only by trace mineral impurities.

Field identification & locations

In the field, it is identified by its extreme toughness, density, and sound when struck. In a jewelry setting, identification requires gemological tools like a refractometer and microscope to distinguish from glass or dyed quartz.
