Durability and WearabilityConsidering the durability of your stone also depends on how often it could fracture, dry, or even dent over time. Although some gems, like topaz, are harder than others, it is not a true indicator of what the gem can handle. Some softer gems are known to be more durable, like jadeite. Toughness can also be measured by other aspects such as cleavage, tenacity, and sensitivity.
