FANCY GREEN DIAMONDS

If you associate fancy green diamonds with extreme rarity and desirability, you are absolutely right. Pure green diamonds are among the rarest gemstones in nature. Their remarkable colour is formed over millions of years as the diamond is exposed to natural radiation deep within the earth. This process alters the crystal structure without making the diamond itself radioactive.

Like all natural coloured diamonds, green diamonds often display subtle secondary hues, resulting in captivating variations such as bluish green, yellow-green, or blue-green. However, the presence of grey, brown, or excessive yellow undertones can significantly impact their value, making pure, vibrant greens exceptionally prized.

The origin of a green diamond’s colour natural irradiation is often evidenced by faint surface markings, sometimes referred to as the “natural” skin of the rough stone. Expert cutters will often preserve a portion of this surface as proof of the diamond’s natural colour origin, an important factor in its authenticity and value.

Among the most celebrated examples is the Dresden Green, an extraordinary 41-carat diamond renowned for its historic significance and exceptional colour. Discovered long before laboratory irradiation techniques were developed, it remains a benchmark for identifying natural green diamonds. In 1904, Sir William Crookes famously demonstrated that radiation could induce a green hue in white diamonds, further deepening the appreciation of the rare naturally green coloured gems.

A natural fancy green diamond is not only rare - it is a true marvel of nature.
