People use the saying "out of this world," to praise something as exceptional.

人们用谚语“out of this world”来称赞某样东西是非凡的。

But, at auction house Sotheby's Dubai, officials are using the term literally.

The company announced this week that it will sell a black diamond that they say is believed to have fallen to Earth from outer space.

该公司本周宣布，将拍卖一颗黑色钻石，据信这颗黑钻石是从外太空坠落到地球上的。

Sotheby's calls the large black diamond, "The Enigma."

苏富比拍卖行称这颗巨大的黑色钻石为“谜”。

It weighs 555.55 carats.

One carat equals 200 milligrams.

The rare stone was shown to reporters at Sotheby's on Monday.

Experts at the National Space Foundation in the United States call black diamonds "carbonado diamonds."

美国国家太空基金会的专家称黑钻石为“carbonado diamonds”。

On its website, the science organization writes that carbonado diamonds form during supernova explosions.

该科学组织在其网站上写道，黑钻石是在超新星爆炸期间形成的。

"Black diamonds," the website says, "were once the size of asteroids a kilometer or more" across when they first began to hit Earth.

该网站称，“黑钻石”刚开始撞击地球时，“直径有一千米或更大的小行星那么大”。

Carbonado diamonds are extremely rare and are found naturally only in Brazil and Central Africa.

黑钻石极其稀有，只在巴西和中非容易发现。

Experts say study of the stone's chemical structure leads them to believe they come from space.

专家表示，对这块石头的化学结构的研究让他们相信它们来自太空。

Sophie Stevens, a jewelry specialist at Sotheby's Dubai, told The Associated Press that the number five has a great importance to The Enigma.

迪拜苏富比拍卖行的珠宝专家索菲·史蒂文斯告诉美联社，数字5对“谜”来说非常重要。

Along with its carat weight, the diamond also has 55 facets.

除了它的克拉重量，这颗钻石还有55个刻面。

Facets are the flat surfaces of a cut gem.

刻面指的是被切割的宝石的平面。

Stevens explained that the shape of this black diamond is based on the Khamsa, an important symbol in the Middle East and northern Africa.

史蒂文斯解释说，这颗黑钻石的形状是以中东和北非的重要符号——哈姆萨为基础的。

"It stands for strength and it stands for protection."

“它象征着力量和保护。”
