Quartz (''Gwindel'' ?) with Muscovite

Item Description

This specimen is labeled as being a "Gwindel", and although I can look down the front face and see what appears to be a slight "twist" to the crystals, I'm not 100% convinced this is an actual "Gwindel" and not just a group of compressed crystals that have a gentle distortion to their form. With that said, it's a showy specimen from one of the greatest mineral-producing areas in all of European mining history, showing a group of sharp, lustrous, well-formed, colorless hexagonal crystals that are compressed along one axis, showing some rather defined striations along the prism faces, which are associated with fine quality hexagonal blades of pseudo-metallic silvery-bronze colored Muscovite all over the back. The largest Muscovite measures 7 mm across. Very good quality, no major damage, and an eye-catching example that dates back well over 200 years! Collection #27.

This specimen is from the collection of Robert Ferguson, Esq., of Raith, the Scottish aristocrat and politician who lived from 1767-1840. Ferguson was the namesake for the species Fergusonite, and assembled his mineral collection from 1790 through 1830, though the bulk of his acquisitions took place from 1795 to 1805, thanks to his close relationships with most of the premier collectors and mineralogists of the day throughout Western Europe. Keep in mind that Ferguson built his collection during a time before mineralogy was a true science. Ferguson's collection was, "for richness and extent is surpassed by few collections of this sort in the kingdom” (Mineralogical Record, Page 170, Vo. 25, No. 6, 1994).

Ferguson was elected a member of the Royal Society in 1805 (after he was detained in France in 1804 by Napoleon during the war between England and France) and was a member and trustee of the newly-formed Geological Society, one of its first four Vice Presidents, serving between 1810 and 1815. All four Vice Presidents were Fellows of the Royal Society who had established large and important mineral collections; their patronage was therefore keenly sought in order to bestow prestige and credibility on the young Society.

Ferguson's life was not without controversy as he had a famous affair with Lady Elgin (the wife of Lord Elgin (of Marbles fame). In 1808, Elgin sued Ferguson, and was found guilty by the court and ordered to pay 10,000 Pounds for the demise of his marriage and public humiliation. For reference, this sum is roughly $4,600,000 in today's currency as a single British Pound was backed by .23 troy ounces of gold. Ferguson eventually married Lady Elgin and spent the rest of his life with her.

These specimens were acquired through a partnership between Rob Lavinsky (Arkenstone) and John Veevaert (Trinity Mineral Company) in May of 1998 to purchase the pieces from UK mineral dealers Gregory, Bottley and Lloyd. All of the specimens were sold in 1999, every one of them, though we recently re-acquired this piece (along with others in this auction) over 20 years later to proudly offer once again.
