Coloured Diamonds
Dazzling coloured diamonds are highly prized and extremely rare. Each is stone one of a kind—hue, strength and purity determining its value. Let's explore the spectrum of colours of the planet’s most valued gem.
Blue Diamonds
Blue diamonds are among the rarest and most valuable gemstones. Many diamonds in this colour range are sourced from South Africa and the Argyle mine in Australia. Blue diamonds form in the lower parts of the earth's mantle, Boron impurities creating brilliant blue hues. The most famous of the blue diamonds is the one and only Hope Diamond.
Pink Diamonds
Natural pink diamonds are some of the rarest and most sought-after in the world. The feminine pink hues are popular amongst diamond connoisseurs. Vivid coloured stones are extremely valuable and rare. Australian pink diamonds account for 95% of natural pink diamonds on the market.
Yellow Diamonds
Diamond collectors love stunning yellow diamonds. Nitrogen causes a diamond to appear yellow, the intensity dependent upon the varying nitrogen levels. Yellow diamonds are often cut in fancy shapes, like the radiant cut, to exemplify the bright colour and maximise intensity when viewed from above.
Green Diamonds
Natural-colour green stones with saturated hues are the most highly prized and sought after. These diamonds are coloured either by radiation exposure or by nitrogen, hydrogen, or nickel impurities. Fine natural green diamonds are mostly sourced from South America or Africa.
Black Diamonds
Distinctive and unusual, black diamonds offer the wearer something unique. Most naturally coloured black diamonds get their colour from a mixture of inclusions such as graphite, pyrite or hematite. Natural-color black diamonds typically are opaque, with a high lustre that gives the stones an almost metallic appearance.
