Green diamonds are among the rarest of all fancy colors. The green color is caused by exposure to radiation or radioactivity and is extremely unique. Natural radiation creates an external skin or surface of green color. It is uncommon for the green color to reach deep within a diamond.

Lab graders assess the natural color of green diamonds by this skin. Irradiated green diamonds are often found in the marketplace, so determining natural color for value is key. Labs may be unable to conclusively determine the natural origin of green diamonds because the cause is radiation.

1.56 carat, Fancy Vivid Green Diamond

Green is the color between blue and yellow, so common secondary colors in green diamonds include bluish green and yellowish green, and if the color is desaturated, grayish green or brownish green. Natural green diamonds are second to red diamonds as the world's rarest fancy color. True greens devoid of secondary hue are the most valuable among natural green diamonds. The green diamond has a very strong emotional correspondence with safety as it is the most restful color for the human eye. Green suggests both stability and endurance. Aqua green is associated with emotional healing and protection while Olive green is the traditional color of peace.

The Dresden Green is a 40.70 carat, pear shaped stone with a VS1 clarity grade. It was reported as one of the largest and finest natural green diamonds ever discovered.

The Ocean Dream The diamond is a 5.51-carat, fancy deep blue-green, shield-shaped diamond. It is the only natural diamond known with this color combination.

Most Expensive Meal in the World

A super luxury dining experience, served with a blue diamond ring, was sold to Ville Oehman, a cryptocurrency expert and founder of jewellery brand V Diamonds. Later this year, Oehman is going to launch an initial coin offering (ICO) – a concept similar to initial public offering – to sell the diamond ring. In other words Oehman is giving away the experience (without the ring) to one of those with a stake in the ICO.

A meal at Singapore’s Ce La Vi restaurant has been dubbed as the most expensive in the world – a whopping $2 million. For that money the personalized, diamond studded chopsticks worth $17,000 per pair are yours to keep. The gold-plated chopsticks are set with 4-carat round diamonds. But there's more. The buyer will get luxury rides – including a helicopter and cruise – leading them to the dining venue at Marina Bay Sands Hotel and a 2-carat blue diamond ring in rose-gold at the end of the meal.

To make it a truly personalized experience, even the furniture will be custom-made, and to finish the night with a bang, fireworks will accompany a Louis XIII de Rémy Martin cognac when the ring is presented. Very naturally Ce La Vi will be closed to the unwashed peons and the lucky couple will be dining in complete, well heeled, privacy.
