Sepiolite (ex Kay Robertson Collection)

Item Description

An old specimen of what was once called "Meerschaum" (seafoam) as well as "l'Ecume de mer" and "keffekill". Sepiolite is an uncommon hydrated magnesium silicate, with a similar appearance to Palygorskite or "mountain leather". Specimens are rare today from this Austrian locality. This piece features off-white fibrous Sepiolite semi-fibrous "needles" sitting on host rock matrix. A great piece to add to any rare mineral collection. Ex Kay Robertson Collection (#6862). Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record and the 50+ page article in the German Magazine "Mineralien Welt" November-December 2017).
