A stone’s durability is an important factor in determining the type of jewellery it's best for and to indicate how to care for and treat the stone. Gemstone durability is measured in three categories: hardness, toughness and stability.
Hardness is an expression of the stone’s ability to resist scratches. The Mohs scale is commonly used to rate hardness and ranks minerals from one to ten, with ten being the hardest.
Toughness is measured by how well a stone resists breaking, chipping or cracking on impact. Every stone, even a diamond, will fracture if it is hit hard enough. Toughness is rated as either poor, fair, good, excellent or exceptional.
A material will be altered by exposure to light, heat or chemicals and its tendency towards alteration is referred to as it 'stability'. Many stones should not be exposed to acids and some, such as amethysts, are light sensitive, fading if exposed to strong light for long periods.
Referring to parts of the process controlled by humans, with the exception of cutting and polishing which improve the appearance, durability or value of a gemstone, treatments are a way of refining a stone’s appearance and are comparable to the way in which other natural materials, such as leather and cotton, are treated through processes such as tanning, bleaching or scouring.
