Gemstone hardness, based on the Mohs scale, contributes significantly to the degree to which a gem will show wear. This is often referred to as wearability or sometimes “durability.”Quartz which has a hardness of 7 is a component of dust and one of the most common minerals on Earth. Simply wiping off the dust from a softer material (i.e., hardness below 7 on the Mohs scale) will scratch it. Diamonds with a hardness of 10, rubies and sapphires with a hardness of 9, or emeralds with a hardness of 8 will remain bright and lustrous for years because they are harder than most of the abrasive particles that contribute to wear, making them excellent choices for engagement rings.On the other hand, a paraiba tourmaline with a hardness of 7 or an opal with a hardness of 6 or a pearl with a hardness of 4 will be rapidly covered with fine scratches and lose their polish if worn every day as a ring stone. The scratches may be tiny, even microscopic, but they’ll accumulate and become visible over time, they are definitely more delicate, so we don’t recommend them for an engagement ring that you plan to wear every day.
