Black Gemstones

Technically speaking, black isn’t a colour. Black is the darkest tone you can get. In gemmology, black actually refers to the relative darkness or brightness of a hue, rather than tone and saturation associated with colour. However, regardless of the technical term, these gemstones are referred to as “black” in colour when described by professionals.

The world of black gemstones is a realm of unique elegance and beauty. From the rarity of black diamonds and black pearls to vibrance of a black opal, each black gemstone brings its own unique character, especially in the world of jewellery. In addition to its aesthetic appeal, black gemstones captivate and inspire jewellery artisans and enthusiasts alike.
