This is the Malawi Blue Agate that has been acid etched to remove all of the matrix, leaving only Blue Chalcedony behind. In years gone by pure Blue Chalcedony cost a fortune and the mineral material was R900 to R1,500 per kilo at the deposit (Namibian Blue Lace Agate remains at least twice as expensive as the Malawi material even today, if and when it is ever available). This is a bargain and they have nice crystalline vugs in these.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePRODUCT DESCRIPTION\u003c\/strong\u003e\u003cbr\u003eChalcedony is a microcrystalline variety of Quartz made of very fine fibres.
