(N.B. The Topazos of Pliny (79) is undoubtedly referring to forsterite from St. John's island, Egypt. His \"chrysolithas\" may have been pale forsterite, emrald, green quartz, topaz or any other golden green stone). The earliest modern name given to an undisputed olivine group species was chrysolit (chrysolite) and was named by Johan Gottschalk Wallerius in 1747, although the name chrysolite was later used by Balthasar Georges Sage in 1777 for what is now known as prehnite. In 1755, Antoine Joseph Dezallier d'Argenville called this species \"peridot ordinaire\", while Axel Cronstedt named it \"gulgron topas\" in 1758. In 1772, Rome d'Lisle renamed the mineral \"chrysolite ordinaire\". Wallerius's chrysolite was renamed, olivine, in 1789 by Abraham Gottlieb Werner for the usual olive green color of this mineral (N.B. chrysolite has a similar etymology.) Friedrich Walchner in 1823 gave it the name \"hyalosiderite\". Named forsterite in 1824 by Serve-Dieu Abailard \"Armand\" Lévy in honor of Adolarius Jacob Forster [April 6, 1739, Grossbreitenbach, Thuringia, Germany - May 1806 St. Petersburg, Russia], German mineral collector and mineral dealer, who variously resided in England and Russia. Boltonite was introduced in 1835 by Charles Upham Shepard, while glinkit was named in 1847 by Romanovski.","2026-03-16

This material is EXTREMELY hard to come by on the market and is in both color and form quite distinct from the much more common Pakistani material mined in the late 1990's. Additionally, the clarity is remarkable for the species; and it allows you to fully appreciate the lovely green color. The luster is superb, and the crystal is nicely terminated. There is a small conchoidal fracture on the backside of the termination (not facing the viewer and not visible in any way from the front) and a larger conchoidal fracture at the center of the lower-rear face (again invisible from front); but otherwise the crystal is complete on the display face and around the sides. FRONT AND BACK PHOTOS ARE SHOWN. It is of remarkable size and is one of the two best I have seen for sale in recent years. It was purchased in the 1980s from dealer Herb Obodda who had obtained it in an old collection (the current collector thinks it was ex. Swoboda but I have no proof of it).
