Collection: Sapphire

Sapphire is a precious gemstone often thought of as blue but with a colour spectrum of white through to blood red.  Red sapphires are categorised as ruby.  Our Ojewellery Sapphires are in the blue and inky blue range.  They are sourced from Australia.

Sapphires are valued based on their colour, clarity, cut and carat (size).   The most desirable being vivid blue, eye clean (so no visible flaws to the naked eye, cut in an even way to optimise light reflection and a big size.

Sapphire has a hardness of 9 on the MOHRs scale of mineral hardness with diamond being at the hard end of the scale with a hardness value of 10.  Rubies are the same and emerald just a touch lower at 7.5-8.

Its refractive index (speed light travels through the sapphire) of 1.76 with emerald being slightly lower, ruby the same and diamond around 2.4.

Sapphires are associated with purity and wisdom.  They are the birthstone for September.
