Green diamonds are among the rarest of all naturally coloured diamonds. Only an exceptionally small number develop their distinctive green hue through a remarkable geological process that unfolds over millions of years.

Unlike most coloured diamonds, their colour is not created by trace elements within the crystal. Instead, it is the result of natural radiation from the surrounding rock deep within the Earth. Over immense periods of time, this exposure subtly alters the diamond's crystal structure, producing its rare green colour — a phenomenon found only in the most exceptional of circumstances.

The colour ranges from delicate green tones to deep Fancy Green and Fancy Vivid Green. Many green diamonds also display subtle secondary hues of yellow, blue or grey, making every stone entirely unique.

Only the finest green diamonds retain their colour throughout the cutting process while achieving exceptional colour, clarity and cut. For this reason, natural green diamonds are among the world's most coveted collector's gemstones, often commanding values comparable to the rarest pink and blue diamonds.

Notable deposits have been discovered in Brazil, Venezuela and Zimbabwe. Yet green diamonds remain so rare that they are only exceptionally found in commercial quantities.
