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. This specimen features three interconnected balls, the standard form for this important find. 5.2 x 3.4 x 2.5cm
