Gyrolite (ex Henry de Linde Collection)

Item Description

While Gyrolite is not a zeolite species (it's actually the namesake for its own group of minerals), it is commonly affiliated with the famous zeolites from the Deccan Trap in India. Without question, the finest examples of this rare silicate species are found in India. Here we have an attractive and fine quality specimen featuring a beautiful yellow colored spherical group of Gyrolite measuring 2.2 cm across perched atop a layer of sparkling drusy colorless Quartz on basalt matrix. Most collectors don't have a good Gyrolite in their collections, and this particular piece is a stellar example of a mineral that is rarely seen outside of India in good crystallized display quality specimens. Valued at $900. From the collection of Henry de Linde (March 21, 1923 – April 4, 2019) of Hot Spring, Arkansas. Henry was one of the most prominent figures in the history of Arkansas mining and mineral collecting. Along with being a miner, mineral collector and an amateur mineralogist, de Linde was one of the founders of the Coon Creek Association mineral club. He was the owner of several key localities in Arkansas including the Diamond Jo Quarry (on the south rim of Magnet Cove), the type locality for Delindeite, which was named in his honor in 1987.
