The present invention relates to a process for producing a fine diamond characterized by that an explosive composition containing a compound having an
aliphatic hydrocarbon ring with 4 to 15 carbons, a fullerenes or a tubular or fiber carbon nanostructure having a diameter of 1 to 100 nm as a...

The physical structure and chemical bonding of
the carbon in solid detonation products (soot)
are largely unknown. It is well established that
diamond can be manufactured by the
application of explosive shocks to graphite
loaded into the explosive, or in a fixture external
to the explosive. Here we report the formation
of diamonds as a chemical product of the
detonation process itself. The diamonds we
observe are =7 nm in diameter and make up 25
wt% of the soot; in size and infrared spectrum
they resemble diamonds similarly isolated from
meteorites.
TNT Explodes at Soviet Post
New York Times 8vii88
MOSCOW, July 2 (Reuters)—Eight tons of
TNT exploded at a Soviet anti-aircraft
installation near Khabarovsk in the Far East,
causing extensive damage and injuries but no
deaths, the press agency Tass reported today.
The explosives, which were stored in military
warehouses, blew up on Wednesday "in the
area of deployment of an anti-aircraft unit near
Khabarovsk," Tass said.

I'm not sure if we had a little thread here some years back or if it was many years ago at alt.engineering explosives - but this is a very intriguing
subject. Unfortunately the diamonds produced (TTBoMK) were very tiny industrial-grade. I may have a scan from Explosives Engineering on a European
technique using graphite. However I believe that the technique may be more popular than it seems superficially. At the above article we have a date of
'06 and a size of 7mm; years back that would be unheard of - it would be so huge!
Several months back I had bought some drill bits (hobby level) and was surprised at their low cost. It's very possible that many of the countries that
have taken our manufacturing base are also producing industrial diamonds (bit were from Mainland China of course).
I'm going to see if I can add to this as it was (& still is) a fairly well used technique. In terms of cost vs yield for industrial-grade I
believe it may be very cost effective.
