What makes Argyle Diamonds different from other diamonds?

Argyle diamonds are Australian diamonds. They come from the world's largest diamond producing mine. Argyle diamonds have two very unique and outstanding features: they are actually harder than other diamonds and have a tendency to fluoresce under ultra-violet light. Their hardness factor results from the unusual atomic structure of Argyle diamonds - their atoms are bonded together in a more complex arrangement than other diamonds. This structure is also one of the major reasons for the deep colours of the Argyle product mix, especially the champagne and pink colours.

What is the most rare diamond in the world?

Why are pink diamonds so small yet so expensive?

Pink diamonds are the world's most rare and highly sought after diamonds. The Argyle Diamond Mine in Australia is the world's foremost source of pink diamonds but even then, only a handful are mined each year. Pink diamonds are expensive because they are scarce. They are found in a variety of sizes however; the larger gems are sold by private tender at the exclusive Pink Diamond Tender, which is held every year. They have been known to fetch up to US$1 million per carat.
