Emeralds are rated 7.5 to 8 on the Mohs scale of mineral hardness, making them relatively durable for everyday wear. However, they are softer than diamonds and sapphires, which means they require careful handling to avoid scratches and chips. It's advisable to remove an emerald ring during heavy physical activities. With proper care and maintenance, an emerald ring can last for generations and become a cherished heirloom.
