Moissanite's Hardness & Toughness
Moissanite's brilliance outshines every gemstone, but its exceptional durability is truly remarkable to say the least. Moissanite is a gemstone that will endure for generations and beyond. Durability consists of hardness, toughness and stability.
Moissanite is Tougher than Diamond
The ability of a gemstone to remain intact, withstand force (pressure) and resist breaking or chipping is known as toughness. Determined by a substance's atomic and chemical structure, toughness can vary directly within a gemstone. While both Moissanite and diamond are rated excellent in toughness, Moissanite has a different atomic structure than diamond which does not have a direction of cleavage (which sometimes is considered as a direction of structural weakness) like diamond. Simply said, Moissanite outranks diamond in overall toughness.
Durability: Impervious to Heat & Chemicals
Durability is a material's ability to remain intact or withstand exposure to temperature and chemicals. Moissanite can easily withstand temperature variations during the jewelry manufacturing process and repairs at a jeweler's bench (unlike other gemstones such as cubic zirconia or emerald). In fact, Moissanite has a higher vaporization temperature than diamond and can withstand temperatures reaching 2,000 degrees Fahrenheit.
Moissanite is one of the hardest gemstones on earth
Hardness refers to a gemstone's resistance to being scratched or abraded and is commonly expressed as a number ranking (1 being the softest and 10 being the hardest) on Mohs relative hardness scale.
