Enigma, the classy ornamental Black Diamond was listed as the largest cut diamond in the world (the 2006 Guinness Book of World Records). The black diamond weighing 555.55 carats gets an auction at Sotheby's. An anonymous bargain hunter placed a final closing bid of $4.28 million and became the new owner of the Enigma. Bidding begins on February 3 at 6 am PST (1400 GMT) and closes on February 9. The sale of this precious gem has fueled the curiosity of its origin. It is a possibility that this gemstone has landed from outer space.

The Jet black diamond belongs to the carbonados category. The category is different from the conventional single- crystals diamonds. In fact, carbonados are configured with an interlocking network of crystals. This interconnection resists fracturing under pressure. These valuable stones are industrial abrasives. They are applied as drill bits to puncture tough rock.

The tough carbonados are opaque, and full of visible holes, exhibiting a unique combination of physical and chemical features. These stones are found in only two regions of the world—Brazil and the Central African Republic—.The gems are known to grow outsize. Carbonados includes the Brazilian carbonado known as Sergio with a colossal mass of 3,167-carat. It is the largest diamond ever found. Second is the Enigma about the size of a racquetball.

The origin of Enigma is still vague. The earthy minerals that compose the regular diamonds are absent in carbonados. Instead, geologists have identified some assorted bunch of metals including the titanium nitride mineral osbornite- elements found in meteorites. It is, therefore, thought that diamonds are formed on carbon-rich stars or planets. Later, bits of these celestial bodies were landed on Earth via meteorites. The process dated back to a period between 4 and 3.8 billion years ago when space rocks regularly bombarded the Earth.

According to the geologists, carbonados were formed when Earth's plates were still moving and the oxygenation of the atmosphere was taking place. However, there are some cosmic assumptions surfacing about their origin.

The curator of mineral sciences at the Natural History Museum of Los Angeles, Geologist Aaron Celestian, told Reuters on Wednesday.

"They are shrouded in mystery as to the origin or formation because there's not that many of them found on Earth, there's also interstellar hypotheses that suggest that they grew in space and then later fell on the surface of Earth."
