    Are coloured diamonds real?

    Yes! diamonds may occur naturally in various colours, including yellow, blue, green, pink, red, and brown. the colour is typically caused by the presence of trace elements or other factors during the diamond's formation process. for example, nitrogen can cause a yellow colour, while boron can result in a blue hue. distortions in the crystal lattice during formation can also contribute to the beautiful shades we see in natural pink diamonds.

    Are fancy-coloured diamonds more expensive?

    Fancy-coloured diamonds are often more expensive than their colourless or near-colourless counterparts due to their rarity and unique appeal. some colours, such as blue, pink, and especially red, are rare and can command significantly higher prices.


    The value of a coloured diamond is influenced by several factors, including the intensity and hue of the colour, the clarity and carat weight of the diamond, and the rarity of the particular colour. for more information, please see our diamond buying guide.

    What colour diamonds are available?

    At nina’s jewellery, we have natural coloured diamonds of many colours available for purchase, including argyle pink diamonds, argyle blue diamonds, champagne diamonds, green diamonds, orange diamonds, yellow diamonds, and white diamonds.

    What is the rarest colour for a diamond?

    The rarest colour for a diamond is red. there are only about 20-30 natural red diamonds, making them highly sought after by collectors. the red colour in these diamonds is thought to be caused by distortions in the crystal lattice structure due to intense pressure during formation. their rarity, combined with their striking appearance, makes red diamonds some of the most valuable and expensive diamonds in the world.
