While diamonds and sapphires are both very hard stones and quite durable, they can still chip and break due to being natural, organic material. Items like rocks, cement, concrete and metals like steel, can chip, scratch or break your stone. Because of this, we generally recommend harder stones like diamonds and sapphires for everyday wear. Although these harder stones can still be damaged, it is less likely they will. Other gemstones that are not as tough, like tourmaline, garnet and morginite etc, are generally not recommended for everyday wear. Sometimes if your stone is heavily included or has large inclusions, these can also affect the structure and durability of your stone and can cause them to break easier. We note these inclusions on our gemstone listings. To avoid your stone chipping and breaking see our jewelry care guide here.
