Sapphires score a 9 on the Mohs scale of hardness, making them one of the hardest and most durable gemstones in the world—second only to diamonds, which rank at 10. This exceptional hardness means sapphires are highly resistant to scratches and everyday wear, making them an ideal choice for engagement rings, wedding bands, and other pieces of jewelry meant for regular use.

Unlike softer gemstones such as emeralds, opals, or tourmalines, which require extra care to prevent damage, sapphires can withstand the rigors of daily life while retaining their beauty and brilliance over time. Their toughness is not just about surface hardness but also about their resistance to chipping and breaking, which makes them especially practical for active lifestyles.
