Naked Science 6: Super Diamonds 科學新發現:超級鑽石

Diamonds are worth a lot of money, but super diamonds are priceless.
鑽石價值千金,但超級鑽石卻是無價之寶。

  In the early part of the 20th century, stories swirled about the "curse" of the Hope Diamond, a deep-blue 45.52-carat stone that was being sold by jeweler Pierre Cartier. It was rumored that the diamond had been stolen from the eye of a statue of an ancient Hindu goddess, so Cartier used this legend to add mystique and increase its value. He told his prospective buyer that a temple priestess had laid a curse on whoever owned the stone after it was taken and then rattled a long list of bad things that had happened to its previous owners, which included Indian royal families, Turkish sultans, and Marie Antoinette. The legend grew once The Washington Post picked up the story for a feature article in 1908.
  The Hope Diamond is considered to be one of the world's most fascinating diamonds because it's more than 100 times bigger than the average diamond ring. However, there has been no evidence of a curse, and it has been locked up in a secured glass case in the Smithsonian Natural History Museum in Washington DC since the 1950s. Scientists have been studying this diamond in the hope that they can mimic the unusual properties that make up this super diamond.
  This month, National Geographic Channel's Naked Science 6: Super Diamonds goes deep into the history of this precious gem and sheds light on how scientists are working around the clock to change the future of diamonds. On three different continents, scientists are unlocking the secrets to diamonds and making discoveries. If the perfect diamond could be made in a lab cheaply and mass-produced, technology could be revolutionized. Since most diamonds have natural flaws that are unable to withstand extreme heat or pressure, scientists are racing to outdo Mother Nature and create the ultimate super diamond.

  20 世紀初期,關於希望之鑽的詛咒流傳不斷,這顆 45.52 克拉的深藍鑽石是由珠寶商皮耶爾.卡帝亞所售出。謠傳希望之鑽是從一座古印度女神像的眼睛偷挖下來,因此卡帝亞利用這個傳說賦予鑽石神秘感並提高其價值。他跟可能的買家說鑽石被盜後,一位寺廟的女祭司便對任何擁有它的人都下了咒語,卡帝亞又接著說了一長串前任物主發生過的不幸事件,包括印度皇室、土耳其的蘇丹王和瑪莉.安東妮在內。這個傳說在 1908 年《華盛頓郵報》根據這個故事作出特別報導後,更加地廣為流傳。
  希望之鑽被視為世界上最吸引人的鑽石之一,因為它的尺寸比一般戒指上的鑽石大上 100 倍。然而,一直以來都沒有任何關於詛咒的證據,而鑽石自 1950 年代起就被鎖在一個安全的玻璃櫃裡,位於華盛頓特區的史密森尼自然歷史博物館中。科學家一直在研究希望之鑽,希望他們能模仿造就這顆超級鑽石的獨特性質。
  本月份國家地理頻道的《科學新發現:超級鑽石》深入探究這顆珍貴寶石的背後歷史,並進一步帶您了解科學家正如何日以繼夜努力來改變鑽石的未來。3 大洲的科學家正逐步解開鑽石的秘密,並有新的發現。如果此完美鑽石得以在實驗室裡便宜製造出來加以量產,那科技將會有重大的變革。因為大多數的鑽石仍有其自然缺點,無法承受極度高溫及高壓,科學家正加緊腳步想超越大自然,製造出終極的超級鑽石。
