Gem and mineral hardness is measured on the Mohs scale. The numbers are based on the relative ease or difficulty with which 1 mineral can be scratched by another. Simply the Mohs calibration is deceptive. The steps between the minerals are non evenly spaced. For example, diamond is only one number away, merely it's many times harder than gems in the corundum family unit.
Corundum (ruby and sapphire) is relatively hard—9 on the Mohs scale. Information technology has fantabulous toughness and no cleavage, which is a tendency to suspension when struck. This makes it a bang-up choice for rings and other mountings subject to daily clothing.
Sapphire ranks 9 on the Mohs hardness scale.
Stability
Corundum is stable under normal wearing conditions, which means it's resistant to the effects of rut, light, and common chemicals. Boric acrid powder volition etch the surface of even untreated stones. Fracture-filled, cavity-filled, and dyed stones can exist damaged by fifty-fifty balmy acids like lemon juice.
Cleaning
Warm, soapy water is always safe. Ultrasonic and steam cleaners are usually safe for untreated, estrus-treated, and lattice diffusion treated stones. Fracture-filled, crenel-filled, or dyed cloth should only exist cleaned with a damp cloth.
Handling and durability considerations
Untreated and fifty-fifty oestrus-treated sapphire is very durable.
Stones that have undergone lattice diffusion handling have varying degrees of treated-color penetration. In some stones, the treated color penetrates the entire rock, while in others there's very shallow penetration. Surface impairment or re-cut can remove the color from lattice diffusion treated stones with shallow colour penetration.
Fracture-filled stones accept surface-reaching fractures filled primarily with high-atomic number 82 content glass. The filler tin be damaged through contact with a variety of chemicals. Fifty-fifty relatively mild substances like lemon juice can crusade alteration of high-lead content glass.
The number of sapphires filled with high-lead content glass is much lower than the number of rubies. In some cases, the amount of glass filler in a sapphire can be quite extensive. Sapphires treated this way require greater intendance than untreated, estrus-treated, or lattice diffusion treated sapphire.
