Stone Diamond is the hardest known mineral to man, formed by the elemental forces of heat and pressure up to 50 miles below the earth, more than three billion years ago. This universally adored precious stone is 140 times harder than sapphire and ruby, which explains why it is symbolic the world over for everlasting love. The' brilliance' and 'fire' within a diamond is caused by its high refractive index - the highest of any naturally occurring gemstone - so the light will bounce and reflect within the stone, which along with its ability to be highly polished, creates the exquisite 'sparkle' effect.
