A few hundred years ago, master Chinese craftsmen who worked with jade daily recognized that some of the jade obtained from Burma (now the Union of Myanmar) was different. It was harder, denser, worked more easily, and produced a higher luster upon polishing. It gradually became the form of jade preferred by Chinese artisans and the jade most highly prized by the Chinese people. They realized this long before scientists differentiated jadeite and nephrite in 1863.
Jade boulders can be very difficult to transport without damage. Human and animal labor was the only way to transport them historically. Today in some areas that is still the only way to move the boulders to market. Where economics allow, a helicopter with a basket or sling on a cable will fly in to difficult areas.
