4 Things to Know About Green Diamonds

• Natural green diamonds are considered to be one of the rarest color of diamond.
• Green diamonds were exposed to radioactive material during their formation, but are completely safe to wear and handle.
• Langerman classifies green diamonds using evocative names such as olive, lime, and mint to describe their diverse hues.
• Chameleon diamonds, a rare subset of green diamonds, can change color when exposed to intense heat or light after a prolonged period in the dark.

What Are Green Diamonds?

After red diamonds, natural green diamonds are the second rarest. Consequently, pure green diamonds are very difficult to find, and can thus command extreme prices. It is, however, important to remember that mixed green colors such as olive, lime, and mint remain at more reasonable prices. We are always here to help you find something that suits your budget and preferences.

What Makes Diamonds Green?

Unlike most natural fancy color diamonds, which owe their hues to elements like hydrogen, nitrogen, or boron, green diamonds typically gain their color from natural irradiation. This exposure can occur deep beneath the Earth’s crust over millions of years. The interaction subtly affects the diamond’s crystal lattice, altering how light behaves in the stone and creating its mesmerizing green appearance.

Are Green Diamonds Safe?

Yes, natural green diamonds are completely safe to wear and handle. While these diamonds were exposed to radioactive materials during formation, they are not radioactive themselves and pose no danger.

Where Do Green Diamonds Come From?

Green diamonds have been discovered in several locations, including India, the Central African Republic, South Africa, Zimbabwe, Brazil, and Guyana. Among these, Africa remains a significant source, producing some of the most vivid and valuable green diamonds.

How Valuable Are Green Diamonds?

The value of a green diamond depends on the 4 Cs: color, cut, clarity, and carat weight. Among these, color plays the most significant role. Pure green diamonds are extremely rare and command high prices, while stones with secondary hues, such as yellow, gray, or blue, may be more accessible. The saturation and distribution of the green hue also significantly impact the diamond’s value.

Tip: Choose a green diamond with vivid and even color distribution for maximum presence and value. If you would like a practical framework for evaluating natural color, use our Checklist for Buying a Natural Color Diamond.

The Importance of Cut

When describing the quality of a colorless diamond, all four 4Cs are important: clarity, color, carats, and cut. But for natural color diamonds, color becomes the most relevant factor.

For a Langerman diamond, color is top priority. But exceptional color is only achieved through a masterful cut.

For green diamonds, the cut determines how effectively the color is displayed. At Langerman, our master cutters prioritize enhancing the diamond’s natural hue. When working with rough green diamonds, they carefully evaluate the color distribution to create a cut that maximizes vibrancy. Fancy shapes such as radiant, pear, marquise, and Asscher cuts are often preferred over round cuts, as they better showcase the rich color of the stone.

For diamonds with darker tones, shallow cuts may prevent the stone from appearing overly dark, ensuring a balanced and captivating look.
