Cratons extend into the mantle beneath
Mon ,31/05/2010Cratons extend into the mantle beneath the earth. This is where the stones are found those diamonds after forever of being in the earth, changing from dead dung to priceless jewel. Now we all want them, that which we cast away when we lived as beasts in caves. Cratons epitomize in a sense the way diamond really are. There you find the gems in their natural habitat, but we dont believe they belong there, no. they belong on the bodices of royalty. And so we extract them and move them there. Fire in diamond jewelry is its ability to split white light into all rainbow colors. This property, coupled with the brilliance of a piece of diamond, is about the one thing that makes it valuable as a gem. That and the property of the substance to withstand pressures. One extremely hard, dark, imperfectly crystallized type of diamond is ballas. Used industrially, you are not likely to see this as a diamond ring on the finger of a socialite anytime soon. It is beautiful, yes, but it does look like many little diamonds bound together, not a single flawless one.
