Give stones their traditional names

The revised British Standard BS EN 12440: 2008 Natural stone - Denomination Criteria issued in February becomes a national standard this month (July). Suppliers of stone specified to the standard must declare the traditional name of the stone. Annex \'A\' is an extensive list of the traditional names of European natural stones. BS EN 12440 forms part of BS EN 12057, 12058 and 1469 and is compulsory where these standards are specified (H51 and M40) and for CE marked products.
