Red Diamonds, also pink and champaign diamonds, have unique and warming hue creating a one of a kind piece that will be treasured and remembered for a lifetime. Unlike other colored diamonds, their color is caused by a unique deformation in the crystal lattice structure during formation. This gives these diamonds their distinct, vibrant appearance. Our red, pink and champagne diamonds are ethically-sourced from the Argyle Diamond mine in Western Australia; the world's major source of these diamonds. With the closure of the Argyle mine, red + pink diamonds are even more precious and rare!
