Heulandite-Ca

Item Description

A notably fine quality, very aesthetic and sculptural display specimen from Jalgaon featuring gorgeous, highly vitreous, pearlescent, translucent, very pale pinkish colored "fan"-like groups of Heulandite-Ca sitting atop thin layer of white Mordenite on basalt. The largest Heulandite group measures 5.3 cm across. No real damage that I can see, and these are without question among the finest examples of Heulandite in the world. The specimens are iconic from Jalgaon, and do not get enough credit for the size and quality. Their abundance on the market may be why some collectors don't value them as highly, but I would make the case that the sheer volume of so many incredibly high quality specimens is remarkably rare to find in nature and should be appreciated as such. Valued at $2,000.
