Diamonds have many properties that make them the distinct and valued stones you know
and love. Some of the most popular features that make them so special are:
Nature’s hardest material, diamonds are not just beautiful but also tough (a 10 on the Mohs scale of hardness). They’te made from pure carbon and their giant molecular structure means they can only be scratched or damaged by another diamond.
Diamonds exhibit ‘fire’ and brilliance, which creates a shiny, freshly polished aesthetic. Lustre is typically described as vitreous, silky, resinous, greasy and adamantine (diamond-like); rough diamonds have ‘greasy lustre’ while cut diamonds possess an adamantinc lustre’,
This property allows diamonds to reflect light in a special way. The stone will sparkle grey or white (brilliance) inside, while outside it will reflect light into the colours of the rainbow onto a surface. This dispersion is what creates the gorgeous sparkling that characterises diamonds.
Diamonds are capable of withstanding high-pressure environments of more than 600 gigapascals or 6 million atmospheres.
