When we talk about the hardest gemstone, diamond is the king. But when it comes to the toughest gemstone, Jade prevails over other gems. In gemology, toughness indicates the gemstone’s ability to absorb changes in its form without breaking. The gemstone’s toughness highly correlates with its strength and flexibility, in other words, the tougher it is, the more flexible it becomes. Given with high flexibility, these gemstones can be twisted around and formed into different shapes without the risk of breaking. As such, jade is widely used as a primary material in various carved pieces
Jade, which is widely known as “Stone of Heaven”, can be classified into 2 types: Jadeite and Nephrite. These two types of jade have similar looks, but they are classified as two different types because the gemologists found that they have different chemical components. In this article, I will primarily focus on Jadeite.
