The Black Apple is a rare breed from the family of Hua Niu apples. It is cultivated in the Tibetan region of Nyingchi. The apple is a purple hue, with white pulp on the inside. It has a unique color which is due to the region’s high altitude. Apples are exposed to a lot of ultraviolet light which is conducive to dark skin as the temperature fluctuates wildly between day and night. Belonging to the high-end segment of the market, the average Black Diamond Apple costs about 50 yuan. Many farmers are reluctant to grow the fruit since its maturity process can take up to eight years.
The unique apples owe their color to their native geography in Nyingchi, a small city in the mountains of Tibet, where they receive a lot of ultraviolet light during the day but the temperature fluctuates dramatically at night, causing the skin to develop a deep, dark color. The flesh inside is white and bright like any other apple. Although they offer a nice, sweet crunch, Black Diamond apples likely don’t have a higher nutritional value than most commercial apple varieties.
