Jade is a semi precious stone, or rather one of two stones made up of different minerals. Jadeite and Nephrite. Jadeite is rarer, but both stones have been used in ornamental carving for many centuries. Both stones are available in different colours, but in both cases it is the purest shade of green that has the most value. The photo above depicts antique Jadeite buttons from China. And while these stones are beautiful and rare, the next images from Jesse Gray are rarer still, as these beautiful jewels are perishable and one of a kind.
