At first, nobody could believe these were thomsonites when they appeared at the Tucson show earlier this year – they were being sold as something else until “the” expert on zeolites identified them for what they were right there at the show – the biggest and richest thomsonites the world has ever seen! Then there was a mad rush to buy them, of course. Not all are so beautiful, but a few have the gorgeous aesthetics of this one, with a huge, perfect ball measuring 4 cm centred on the sparing matrix, surrounded by smaller balls. 9 x 6.5 x 2.8 cm
