Our Synthetic Malachite is just as beautiful as the natural stone. The greens are so vivid and alive; and we love it's lighter weight which makes it easier to wear! The added concern over mining practices and the health of the miners, has driven us to consciously make the decision to only carry the synthetic. Though labor laws in China now require better ventilation, extended exposure to the dust can lead to arsenic poisoning or silicosis. Rest assured our Synthetic Malachite will help you achieve the same effect as the natural stone, but with less weight on your conscience and your body!
