I'm hearing rumors now that the Russian Duma is considering a new law to prohibit meteorite export - if this is true, it could be rushed through and take effect very soon. The Russians are seeing dollar signs and don't want to those dollars leaving the country without passing through the Kremlin first. This Chebarkul event grabbed a lot of attention, all the way back to Moscow.

This is going to be interesting to watch develop. I just hope it doesn't mean Russia is going to clamp down on new exports. Russia is the source of Seymchan, Brahin, Pallasovka, Sikhote Alin, Saratov, Koltsovo, etc. Will those be restricted as well?

Best regards,

MikeG

That doesn't sound like it's good news.

The last 10 years has since an increase in regulation regarding meteorites. Much of it is due to misconceptions that there is a thriving black market where James Bond villians pay enormous sums of money for smuggled Moon Rocks. Even the New York Times has jumped on the tabloid journalism bandwagon and published a hit piece against private meteorite dealers. That article was rebuked by the same scientist who was misquoted in it and it drew an official rebuttal from the IMCA.

With increased media exposure comes increased liability. The scammers, nuts, and profiteers have been crawling out the woodworks to take advantage of newbies and gullible bidders.

A lot of people have become interested in meteorites lately, and many of them are doing it for the wrong reasons - money, to get attention, vanity, etc. I get a ton of scam emails every week that I delete immediately.

Meteorites have their own TV show now. Meteorites are being mentioned or shown more frequently in numerous documentary films and series on cable TV. Meteorite falls are now YouTube sensations and the media exaggerates every sensational aspect of the event, while paying token lip service to the science involved.

Now we have this Chelyabinsk event that is a modern-day Tunguska on a smaller scale. Tunguska happened just after the turn of the 20th century and it took 20 years for the first teams to reach the area and search. This new impact captured world attention within hours and coincided with the near pass of asteroid 2012 DA14. This was a perfect storm for a media blitz.

Worse, the Chelyabinsk area is a former military industrial complex with numerous secret sites where nuclear weapons were manufactured during the Cold War. Military bases are littered around the region and this event struck the area without any warning and showed how vulnerable we (and the Russians) are to this kind of threat. The Russians don't like feeling vulnerable to anything, and their military is now keenly interested in this event. It's no surprise that the Duma is now getting involved.

But, like all reactionary laws of this nature, the law is being passed after the fact. This means that all specimens that left the country before the law are not bound by it. Many such specimens have already left Russia and are in private hands as we speak. However, the majority of the stones are still inside the country, and if Russia tightly restricts them, it will greatly reduce the amount that comes out later. And that will drive up the demand and price for legal specimens (the grand-fathered ones).

This is technically-true for Canyon Diablos and Campo del Cielos. It is currently illegal to prospect for and recover either one of these meteorites. Yet there are still thousands of them on the market legally.

I'll try to keep everyone updated.

Best regards,

MikeG

Long video, but lots of good shockwave impacts.

I have some Chelyabinsk/Chebarkul lined up through a reliable source, but it may be another week or two before I get my hands on it. When I get it, I will be sure to post some photos. I'm buying a fully-crusted pea for myself (maybe 2-4g) and another gram or two of small fragments that I can resell as micromounts.

From a collector standpoint, I haven't been this excited about a fall in a long time

Coincidentally, a few weeks before this fall, I had decided to rebuild my collection of peas. I used to have a great collection of peas, but I had to sell them off three years ago. Now I am rebuilding for keeps, and Chebarkul will be a nice addition.
