This is an important old specimen probably at least 125 years old, if not more. Before India, these Icelandic zeolites set the standard and were considered both superb specimens and a mark of the sophisticated collector. With lustrous doubly-terminated crystals to 7.5 cm, isolate don basalt matrix, this is STILL a superb heulandite even compared to modern Indian material and yet it is priced about the same, although its a major rarity and classic. 21 x 12.1 x 5 cm
