Blue Diamonds

Blue diamonds are among the rarest of all coloured gemstones. Natural blue diamonds get their colour from trace amounts of boron within the crystal structure — an element so scarce in diamond-forming conditions that blue diamonds represent less than 0.02% of all diamonds mined.

Blue diamonds are among the rarest of all coloured gemstones. Natural blue diamonds get their colour from trace amounts of boron within the crystal structure — an element so scarce in diamond-forming conditions that blue diamonds represent less than 0.02% of all diamonds mined.

The most famous blue diamonds — including the Hope Diamond — have captivated collectors for centuries. Modern blue diamonds range from faint greyish-blue to intense vivid blue, with colour intensity and saturation driving value.

At MOH London, our blue diamond collection includes independently certified stones graded by GIA or IGI. Blue diamonds are particularly striking in white gold or platinum settings, which enhance the cool blue tone.
