Sapphires 101


Are Sapphires Strong, What Does That Even Mean?

In addition to their beauty, sapphires have attributes that make them an excellent gemstone for jewelry.  Sapphires are very durable, which means they are tough and hard.

Because sapphires are tough, they are not prone to chipping, cracking, or breaking. They can be polished to a bright sheen and can take the stress of everyday wear.  Their resistance to chemicals means that your stone will not become etched or lose its polish under normal conditions.Because sapphires are hard, they are not easily scratched or affected by abrasion.

The Mohs Scale of Hardness

Sapphires rate 9 on the Mohs Scale of Hardness, an index of the relative hardness of gemstones.  Each mineral can scratch the ones below it on the scale.  The steps in the scale do not represent a uniform increase in hardness.  In absolute terms, diamond is almost four times harder than ruby or sapphire. Speaking of diamonds,did you know that a natural, untreated sapphire of superior quality is rarer than some diamonds? Rarity plays a key role in the pricing of these lovely gems.
