Consulting Gemological Curator (2007-2018)
Visit the Timothy N. Heasley Mineralogy Museum main page here and updates here.
I served in several capacities and under different titles since 2007 and in collaboration with mineralogist Dr. William A. Bassett. This was at times unpaid, officially paid, partially paid, and I now do so voluntarily indefinitely into my post-60 future while I concentrate on other pursuits (including research, turtoring, travel, and finishing up another book or even two). "Consulting Gemological Curator" was a title coined specifically for me by then Department Chair Dr. Larry Douglas Brown; the first such official title in Cornell University's history and funded by a donation from mineralogist Dr. Olaf Medenbach of Germany.
I take great pride in representing gemology as a relevant geoscience around the world, as well as having done so for my Alma mater Cornell; birthplace of the 125+ year-old Geological Society of America. At this latter event I presented my paper "Scholarly Treasure: the Role of Gems in a University Setting" as part of the first-ever Gemological Session in the GSA's history! For more on that historic watershed event, see: Skalwold, E.A. (2013) Gemology bears triumphant tidings.

Skalwold, E.A. and W.A. Bassett. (2016) Blue minerals: exploring cause & effect. Rocks & Minerals, Vol.91, No.1, pages 61-75 (Special Issue).
Abstract: From its vast expanses of cerulean waters to its azure heavens above, our world is dominated by blue, so it is no wonder that the color blue is favored by many across cultures and throughout the ages. The allure of minerals owes much to the perception of color inherent to a particular species or variety. Arguably, whether a person is a seasoned collector or small child, color is what first attracts attention, and quite often its cause is the earliest question posed. Scientific investigations into its nature and articulation of its nuances of hue and quality are the subjects of volumes of literature in both the mineralogical and gemological sciences. Although the present overview narrowly focuses on a selection of blue minerals and aims to do so with some exploratory tools and twists, its concepts also provide insights into the cause of other colors seen elsewhere in the mineral kingdom, as well as in gemstones fashioned from denizens of that realm.
Of "Blue Minerals: Exploring Cause & Effect," author/gemologist Richard W. Hughes comments: “…But the real praise is for your article on blue minerals. Not only was it beautifully written, but the illustrations were incredible. If only all gemology articles could be as interesting and accessible as this. This article is in my all time top list. And after Billie reads it, I know she’ll feel likewise, as one of your subheads is her favorite Dylan song… Your writing and photography are simply wonderful…” Photo: Faceted Sodalite on Rough, E.A.

Abstract: Optical mineralogy has many fascinating though often complex concepts which underlie common effects observed in minerals and lapidary specimens fashioned from them. Doubling of images such as seen through a calcite rhomb is perhaps one of the most readily observed of these properties and could well have been one put to use centuries ago in a very practical way. The intriguing theory of the Viking’s use of a coveted stone to find their way in arctic waters has its roots in the ancient Viking Sagas, optical mineralogy, and in practical application by modern navigators. The proposed minerals thought to be the Viking “sunstone” are excellent models for understanding the optical phenomena of birefringence and pleochroism; the very properties which make them useful for navigation are also those which make them valuable to mineral and gem enthusiasts today (see Skalwold 2008). There are several candidates for the stone. Among them are “Iceland Spar” calcite of which a coveted optical-quality variety was found abundantly in eastern Iceland, and the blue variety of the mineral cordierite, found in Norway and popularly known as “Viking’s Compass” and as the gem “iolite.” While the latter’s extraordinary pleochroism is explored in the authors’ article “Blue Minerals: Exploring Cause & Effect” (Skalwold and Bassett 2016), the more likely candidate, Iceland spar, is the classic model for demonstrating the phenomenon of birefringence and doubling in optically anisotropic minerals. However, whether one’s adventures with minerals are land-bound or at sea, before venturing far there is some trouble with doubling to untangle first.

Abstract: It might be overstating a bit to say that if one could understand all there is to know about quartz, then everything else in the universe would make sense. Without doubt, this mineral has profoundly impacted many sciences and technologies which we rely upon today. At the very least, quartz provides one with a host of mental gymnastics and a seemingly endless variety of puzzles to ponder. Not least among its fascinating properties is that of optical activity, its manifestation of which results in the special optical figure affectionately known as the “bull’s eye.” In the authors’ article on causation of blue color in minerals, mention is made of the quartz monochromator, an obscure instrument which makes use of optical activity in a very elegant way (Skalwold and Bassett 2016). In hopes of giving readers insights and appreciation for this ingenious device and for quartz itself, the following is an exploration into the nature of the chromatic phenomenon which plays out within this proverbial black box.

Praise for "The Edward Arthur Metzger Gem Collection"|
A book by William A. Bassett and Elise A. Skalwold
This first of two volumes catalogs the entire Collection
John I. Koivula: “…a picture is worth a thousand words and you have done one of the best descriptive collection catalogues ever produced. As a picturesque catalogue it will reach and influence a wide audience - and in the worlds of gems, mineralogy, and gemology we do need to reach many more people in order to preserve the sciences that we so much enjoy…”
Antoinette Matlins: “…an important addition to the trove of sparkling books written for people who love gems and jewelry. In addition to the magnificent photos by Jeff Scovil, and the clear and useful information about the gem families that comprise the collection, there is an intimacy to the text that creates a strong connection to and understanding of the man behind the collection … This is a wonderfully accessible book through which one gains a much clearer understanding of what comprises a real ‘gem’ [along with] the passion, the excitement, patience and commitment that made Edward Arthur Metzger not only a collector, but a connoisseur...”
Richard W. Hughes: “…First of all, I have to say that this is an extraordinarily handsome volume and one that I am proud to add to my library… I am blown away by the collection, both in terms of quality and breadth. You are so fortunate to have had the opportunity to work with something like this. It is a treasure and a gift…”
Dana Schorr (1952-2015): "...It is beautifully done! Congratulations on publishing! You must have put hours and hours into it [and] you did a great job with the resources you had available. I am enjoying perusing the book already. It accomplishes what you set out to do and you should be proud of it… I am proud to put it on my coffee table and let my friends enjoy it. Most times something very fine is better than nothing that is perfect!..." (Tribute to Dana)
Alan Jobbins: “…The photography is outstanding and brings the gems to life - the red diamond is almost in one’s hand and the range of colours of the diamonds is quite amazing. The overall effect is to make the presentation remarkably crisp and so accessible. In addition to the excellent photography and the exceptional range of colours in all categories, on a broad educational front it excites pleasure and arouses the desire to learn…”
John Emmett: “…DOWNRIGHT SPECTACULAR - The collection, but more importantly THE BOOK! The book is actually the more important of the two as it will document for all time such treasures and the book will be studied by more lovers of fine gems than will probably ever see the collection. What a major contribution. Please accept my praise for this fine work and also congratulate your co-author [Dr. William A. Bassett]. I cannot imagine how much work was involved in doing such a project…”
Emmanuel Fritsch: “...there is excellent documentation, which is the first level of science. In that regard, your book has a definite scientific flavor, which would have been absent had it been written by someone less scientifically inclined...”
John Nels Hatleberg: “Fantastic!”
