So? The wikipedia entry supports the Global News article that the "new" Russian diamonds are harder than "traditional" diamonds. (although I'd need some documented evidence to buy the "twice as hard as" claim). Or am I missing something?

Rubbies? What are they? My dog rolls over on his back and I rub his tummy. Is that what they are? Dog tummy rubs?

It's all about that moment when metal that hasn't seen the light of day for generations frees itself from the soil and presents itself to me.

Some years back I read the story about the De Beers Group very interesting group and will be interesting how this plays out. The Mohs scale is just that a scale not a true gauge on hardness. Agate is a 7 or 8 but I have cut Mexican lace agate that was 9 or better and other agate that was soft maybe a 6.
