Russia Reveals Siberian Diamond Treasure


russia reveals siberian diamond treasure


Russia Reveals Siberian Diamond Treasure ... it was a headline that caught my eye. Several industry publications - and more than a few news outlets - carried the story after the official Russian news agency, ITAR-Tass, carried the announcement by the Siberian branch of the Russian Academy of Sciences

The headline Russia Reveals Siberian Diamond Treasure was followed by a paragraph that stated... "Russia has just declassified news that will shake world gem markets to their core: the discovery of a vast new diamond field containing "trillions of carats," enough to supply global markets for another 3,000 years.

As the ITAR-Tass story unfolded, I saw that the "vast new diamond field" was actually discovered in the 1970's, and had been kept secret. Why was it kept secret for so long? I wondered. Some possible reasons came to mind, such as:

    • This diamond deposit is located in Arctic Siberia, renowned for harsh weather conditions

    • Exploiting the field in Arctic Siberia would be difficult

    • Avoid disruption to a controlled diamond market

    • The Soviets were reaping huge profits from existing, productive deposits

The story explained that a gigantic asteroid crater was unearthed, and then studied by Russian geologists and other disciplines. The crater is known as Popigai Astroblem. The best I can determine, Popigai is a place name, and astroblem means an impact crater.

The crater is said to measure 100 kilometers across (62 miles), and is tied with another crater as the seventh largest impact crater known worldwide. The scientists calculated the crater was formed by an extraterrestrial body impacting the earth 35 million years ago.

In the course of studying the crater, they discovered diamonds deep beneath the earth that had filled in the crater. When the diamonds were intensely studied and tested, they were determined to be "impact diamonds" which are twice as hard as most diamonds. 

The hardness and the large grain structure of these stones make them very valuable in industrial and scientific applications, where their more abrasive characteristics are desirable.

A-ha! Just as I suspected, these are industrial grade diamonds, not really suitable for jewelry. Like most other diamonds of extraterrestrial origin, most of these apparently are both tiny in size and below even minimum jewelry quality.

I began to search for and read other reports on the Popigai Astroblem discovery and learned a few more interesting items. The first article stated the crater was the result of an asteroid impacting the earth at tremendous speed. That article speculated the diamonds arrived on earth in the asteroid.

The second news story I found said the crater was a meteor crater. The next few articles stated the crater was caused by a meteorite. I quickly realized that I did not know the real difference between an asteroid, a meteor, and a meteorite. Was it just a matter of size? 

Is an asteroid huge, maybe the size of small town?

Is a meteorite smaller than a shoe box?

Is a meteor in between, around the size of a car?

So I looked it up. All of them are bodies hurdling through space. Only asteroids have to do with size... and I found a new term - meteoroid.

    • An asteroid is smaller than a planet and larger than a meteoroid

    • A meteoroid is outside the earth's atmosphere

    • A meteor is moving through the atmosphere

    • It becomes a meteorite when it hits the ground

I cannot guarantee the accuracy of these explanations, but it all sounds logical.

I found one conclusion of the scientists to be amazing. They concluded the diamonds were not brought to earth by the meteorite, but rather when the meteorite impacted the earth, it made a direct hit on a graphite (carbon) deposit. They determined the diamonds were created from the effects of the heat and pressure of the impact on the carbon.

Russia Reveals Siberian Diamond Treasure - it is an interesting story. It also makes you wonder what other discoveries they are keeping under their Ushankas (hats).

Gem Industry News


Gold Price Forecast - An Alternate View



The August newsletter mentioned a Routers news agency report that their quarterly poll of "gold experts" predicted only a small rise in gold prices by year end.

Now we have a jewelry industry publication carrying a story bearing the headline...

Banks Predict Huge Gains for Gold

The prediction by several major banks are based on what one bank described as "the reckless policy of yet another round of quantitative easing" by US and European governments.

The article says "Citing central banks’ policy of monetary “easing, a growing number of analysts now see gold eventually soaring to $2,000 an ounce—or higher."

The US Presidential election is predicted to have a significant bearing on the stability of near-term gold prices.

Presidential Election Could Influence Holiday Sales


A recent article discussing sales strategy for the holiday season caught my eye because it mentioned "jewelry and other luxury goods" as a category subject to consumer attitudes in light of the national elections.

The article was obviously written from a business perspective. It stated that consumers could be more optimistic (and therefore spend more) if the pro-business candidate won.

The recommended strategy was to sell lower price goods leading up to the election. At the same time, you should be offering your customer the opportunity to upgrade their purchase before Christmas.

When following this strategy, you obviously should make an extra effort to stay in contact with your customers, in order to remind them of the opportunity to upgrade their jewelry gift purchases.

An ailing economy isn't a deal killer when you offer quality, service, and low prices.
