Pink Diamonds: Australia’s Rarest Sparkle

What Makes Pink Diamonds So Special?

Pink diamonds are among the world’s rarest and most coveted gems, famous for their mesmerising blush hues and mysterious origins. Unlike most coloured gems that get their colour from trace elements, the unique pink in these diamonds is believed to come from natural distortions in the crystal structure—known as “plastic deformation”—during their formation. This natural wonder, combined with their scarcity, makes pink diamonds a prized choice for custom-made jewellery and coloured stone engagement rings.

Where Are Pink Diamonds Found?

While pink diamonds have been discovered in Brazil, India, South Africa, Russia, and Canada, over 90% of the world’s supply came from the legendary Argyle mine in Western Australia before it closed in 2020. The closure has made these gems even more exclusive and sought-after, with only a tiny fraction of all diamonds ever mined showing a natural pink hue. For every million carats of rough diamonds, only about one carat of pink diamond is considered gem-quality, making them a true Australian treasure.

Pink Diamonds in Jewellery & Value

Pink diamonds are the epitome of luxury, often gracing bespoke rings, earrings, and pendants. Their value is driven by rarity, colour intensity, and carat weight—deep, vivid pinks command the highest prices, especially when set in elegant, minimalist designs that let the stone shine. With the Argyle mine’s closure, prices for certified pink diamonds have risen sharply, making them not just a beautiful choice for engagement rings but also a smart investment. Whether you’re dreaming of a statement piece or a subtle accent, our team can help you source and design your perfect pink diamond treasure.

Grading and Famous Pink Diamonds

Pink diamonds are graded by the strength and purity of their colour, with the GIA scale ranging from Faint to Fancy Vivid or Fancy Deep. Many pink diamonds also display secondary tones like purple, orange, or brown, which influence their value. Some of the world’s most famous pink diamonds—like the Pink Star and the Williamson Pink—have set records at auction and inspired generations of collectors and jewellery lovers.
