Worth saying plainly, because Brazil is also the centre of the agate dyeing industry, and this particular blue-grey is the reason why. The stone is unusually porous, which lets dye move through it evenly, and the pale base takes colour without fighting it. Nearly every bright blue, pink or green agate slice on the market started as material that looked something like this.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eNothing has been added to this one.
