Durability refers to a quality of gemstones to withstand wear and tear in normal use. It depends on hardness (the ability to withstand abrasion), toughness (a quality of withstanding fracturing) and stability (the resistance against chemical and light attack). Diamond has a very high durability due to it's hardness and stability, it is however possible to break it because of its lower toughness. Most gemstones with a high durability can be damaged during wear under conditions they were not created for, this holds true for precious metals as well. It is best to take off all jewelry while gardening, night rest and active activities such as sports to prevent damage. It is advisable to let your jewelry be cleaned and checked at least once a year by a professional jeweler, more often if needed.
