Is emerald a delicate stone?
Owners worry about the safety of their emeralds. Be aware that emeralds and all other gems (even diamonds) can break. But emeralds are much more durable than softer jewels such as opals, pearls, coral or tanzanite. At 7 ½ to 8 on the Mohs’ hardness scale (where diamonds are 10), emeralds are harder than most steel.
