Facts about Emerald
Hardness
7.5 - 8.0Mohs Scale
Good hardness for everyday wear. Durable enough for rings and bracelets, though they should be stored away from harder stones like sapphire or diamond which could scratch their surface.
The Mohs scale rates a gem's scratch resistance from 1 (softest) to 10 (hardest). Read more about the Mohs scale and why durability isn't just about hardness.
Care Instructions
An estimated 90 percent or more emeralds are fracture-filled. Ultrasonic vibrations can weaken already-fractured stones, and hot steam can cause oil or unhardened resin to sweat out of fractures. Using warm, soapy water coupled with gentle scrubbing is the safest way to clean emeralds.
