There are two Diamond News In November 2015.
Perhaps, the best known diamond is the Cullinan - the rough gem-quality diamond at 3,106.75 carats (about 1.4 pounds). The Cullinan was found in 1905 in South Africa and was named after Sir Thomas Cullinan, the owner of the mine. After it was discovered, it was shipped to England on a steamboat under heavy security. But this was a diversion and in fact, the real stone was sent in a plain box via post. The Cullinan has since been cut into nine smaller stones with the biggest of them, known as the Great Star of Africa, estimated at $400 million. The Gem is in the Crown Jewels of the United Kingdom.
The value of diamonds - as with art - is often set by what the bidder is willing to pay. There are a number of hugely expensive diamonds in the world but there is also another level of so called priceless or inestimable gems that are never likely to be for sale. The most expensive colored diamonds and without doubt the rarest are the Red Diamonds.
Many people have experienced a manipulative offer to invest into "the best quality diamonds". Unless you’re a carbon expert, diamonds are a truly difficult commodity. Some even call it an investment in trust. Unlike gold, which is priced in carats, diamonds are commonly valued by judging four characteristics, known informally as the four Cs. They are now used as the basic descriptors of diamonds: these are carat (its weight), cut (quality of the cut is graded according to proportions, symmetry and polish), color (how close to white or colorless the diamond is, or for fancy diamonds how intense is its hue), and clarity (how free is it from imperfections). However, combinations of these 4 qualities can only give you a vague idea of the price you should pay for a diamond.
There is, of course, always a story behind it and you must ask yourself how much you value the story ...
