Billions of diamonds secrets of Russia

The secret was kept for more than forty years, but Russia has declassified documents that will "revolutionize the diamond market," says the Christian Science Monitor. In the 1970s, when they were researching in Eastern Siberia, the Soviets discovered in a crater of a huge asteroid diamond deposit, containing nearly "1 000 000 000 000" carats. Enough to supply the world market for over three thousand years, the newspaper said.

Russian authorities at the time had decided to withhold this information, to avoid competing with the diamond mines of the region of Yakutia, which flooded the market already highly controlled the gemstone. But the secrecy was lifted by Moscow on 15 September, and scientists have since been allowed to confide in the Russian press.

According to news agency ITAR-TASS, diamonds Popigaï - the name of the crater - are "twice as hard" as usual diamonds, making them "ideal for industrial and scientific purposes." Their constitution so unusual, due to the enormous pressure experienced at the time of the explosion of the meteorite, does not actually use them to create jewelry. These "diamonds from space," as they are called Russian scientists should not rush the diamond market, since it is mainly focused on jewelry.

There are three other craters of the same kind in the world, Mexico, Canada and South Africa, but of Popigaï is the only perfectly preserved. The crater, old 35 million years, is 62.137 miles wide.

All you need to know about the Clarity of Diamonds

 The clarity of Diamonds

Clarity is an important aspect of a diamond, and it is important to know how to grade the clarity of a diamond before you buy one.

the Clarity of Diamonds

It is actually quite easy to learn how to grade the clarity of a diamond.

There are basically two things that you must understand:

Diamonds with visual inclusions and blemishes, and those that are ‘eye clean’ meaning that there are no inclusions or blemishes that can be seen with the naked eye.

From there, the clarity of a diamond is further broken down into subcategories.
Many people mistakenly think that diamond clarity refers to how clear it is. This isn’t so.

Clarity actually refers to the internal and external imperfections of the diamond. The best diamonds, of course get a grade of  FL or IF – Flawless or Internally Flawless – meaning that it is perfect. A grade of  I-1, I-2
or I-3 means that the diamond is imperfect, with a grade of I-3 being the worst.
Other grades are VVS1 and VVS2, which means that the diamond is very, very slightly imperfect; VS1 and VS2, meaning the diamond is very slightly imperfect; SI-1 and SI-2, which means that the diamond is
slightly imperfect.

About the Diamond Weights

Diamonds are measured in Carat Weight.

One carat weighs 200 milligrams. If a diamond is referred to as four grains, this also means that it is a one carat diamond.

Diamond weights

The word Carat comes from the word carob.

A carob is a bean that grows on a tree in the Mediterranean. In times past, if a diamond weighed the same as a carob bean, it was one carob, or one carat.

However, in the far east, where Carob trees do not grow, rice was used to measure the weight of a diamond. If a diamond weighed as much as four grains of rice, it was four grains – or one carat as we know it to be
now.

The majority of diamond purchases are for diamonds that are 1/3 of a carat.

Beware when shopping for diamonds that are already set or mounted. If more than one diamond is used in the piece, the tag on the jewelry will give the CTW or Carat Total Weight – it does not tell you the carat weight of each stone in the piece. You need to ask the jeweler for the total carat weight of the largest diamond in the piece to truly understand what you are buying.
