Jewelry design is a fascinating enigma with its simplicity and complexity
both from a technological and societal standpoint.
Award winner Sean Gilson will speak about design and technology and what today’s jewelry designers need to innovate and thrive. With examples of design, Sean will give an insightful understanding of the importance of design in jewelry.

Renee Newman, GG, Author
Gems that were once only bought by collectors are becoming increasingly popular in jewelry stores and designer boutiques. New finds have made these non-traditional gems more available, and retailers are using the stones to set themselves apart from their competition by creating unusual items to wear and give as gifts.

Her presentation will help you evaluate the quality of unusual gem materials and show you how they can be used to create distinctive jewelry. The session will include photo examples and information on:

"Dr. Allen M. Bassett and the Ruby Mines of Nepal" Plus Two Featurettes: "From Gemology to Mineral Physics & Back Again" and "An Update on a Gem of the Future: Nano-Polycrystalline Diamond (NPD)"
Elise A. Skalwold, BSc, FGA, GIA GG, Consulting Gemological Curator, Cornell University
In the early 1970s, geologist and gemologist Dr. Allen M. Bassett dreamed of building a gem industry in Nepal. An early “Field Gemologist,” his love of minerals – and gems in particular – began as a young boy, never waning as he pursued a doctorate and then a geological career spanning several decades. Early on, his work took him to exotic lands, including a life-changing trip to Nepal as part of the San Diego Himalayan Expedition. Dr. Bassett later became the first Western scientist to trek to these high altitude localities in the Ganesh Himal [Dhading District] and was the first scientist to describe the geology of the region. In his quest to establish a fully integrated gem industry in Nepal, he brought in the first faceting machines, initially starting this endeavor with the unique tourmalines of the Hyakule Mine. He later helped found the Kathmandu-based company "Himalayan Gems, Nepal" and was instrumental in developing the ruby mines of Chumar and Ruyil.

Jerrold Root, GIA GG, FGA
Next to magnification, most truly experienced gemologists consider the spectroscope to be the 2nd most important tool in their arsenal. Why is it then that most run from using it, let alone becoming proficient in the use of this wonderful instrument? After this 2 hour session you will most likely find yourself without a good answer to this question and well on the road to becoming comfortable in the use of the spectroscope. Beginning with the basics of the instrument, you will then be shown how and what to look for. The balance of the session will be dedicated to individual testing and identification of unknown gem materials, while being personally assisted and guided. Some ID’s will be easy, some not so, but Mr. Root guarantees this to be a fun, educational and enlightening experience. Everyone in attendance is required to bring a hand-held spectroscope (diffraction grating or prism), a non LED penlight with fresh batteries, and any textbook you might have with a reference section of sample spectra.

"Chasing Gold to Where it Has Taken Me"
Tom Herman, Jeweler Extraordinare , Seven Fingers Jewelry
Being near sighted can get you quite far. The great Yogi once said, "you can observe a lot by just watching". My interest in detail has driven me since I was quite young. Finding fossils in the limestone along the railroad track or peering into the end grain of a newly cut trunk of wood; I was entranced by the complexity of it all. Come along and I'll take you on a photographic journey through my jewels, inspired by the details in life.

The House of Bolin: Imperial Russia's Premier Court Jeweler
Marie E. Betteley, GG, Antique Jewelry Dealer
"Carl Fabergé has long claimed the role of Russias most famous court jeweler. Little is known about other
Russian imperial jewelers of which at least fifty held the Romanov warrant. The most prominent among them was Bolin. Unlike Fabergé who served the last two tsars of Russia, The House of Bolin produced jewelry for not two but seven consecutive Russian sovereigns beginning with Catherine the Great. And incredible as it may seem almost 100 years after the Bolshevik Revolution, Bolin still continues today in Stockholm. Originally from Sweden, Bolin is known as the oldest, still active jewelry house owned by the same family in history. "

The Lore and the Profits
Dr. Jack Ogden, FGA, FGAHK, FSA, Chief Executive Gem-A,
For thousands of years gems and minerals have had a variety of myths, magic and medicinal properties attributed to them. Scepticism about this gem lore is not new – the Roman writer Pliny was outspoken about the ‘untruths’ regarding gems expressed in his day – and modern gemmologists typically pour scorn on such things. However closer examination shows that there can be reasons for at least some of the associated lore – some scientific, some amusing. Certain attributes associated with Gems in Medieval times can be seen to be simple misunderstandings of what classical writers were trying to say, in other cases some medical properties may indeed be based on truth. Of the apparent ‘untruths’ some were presumably those used by charlatans to sell cures, others may simply have been the exaggerated claims of those marketing jewellery – an approach that is hardly unknown today. This talk will consider some of background to the lore of gemstones in the context of 2000 years of jewellery and show that however sceptical one might be, it provides fascinating insight into gem history as well as providing a wealth of anecdotes that even the most ardent ‘non-believer’ can use to weave history and interest around the gems they are exhibiting or selling.

Spinel: A Once Forgotten Gem on the Rise
Christopher P. Smith, GG, FGA, President of AGL
Spinel has historically been one of the most highly revered gemstones although its popularity had suffered as a result of many factors, including its classification as “semi-precious” and a general confusion with another dominant red gemstone: ruby. More recently though spinel has been making a strong comeback and so its popularity is once again on the rise. Important new sources and even a book devoted to this beautiful and colorfully diverse gemstone have helped to focus attention back onto spinel. In addition to exhibiting a vibrant array of shades and nuances of color, spinel has also traditionally been spared the controversy of treatments that have encumbered many other gem varieties, such as ruby, sapphire, emerald, quartz, topaz, tanzanite, etc. However, today some treatments are starting to be encountered. This talk was a review of the various sources of spinel, treatments and the gemological characteristics that help to distinguish them.

Reflections in a Golden Eye: How to Photograph Jewelry
Joseph Gold, Jewelry Photographer
Photography performs several functions in our world. One is to represent the actual and another is to evoke emotion. An image of jewelry as it actually appears relies on a technical approach. This would be the sound course for an appraiser. On the other hand, if you are trying to sell jewelry, then an emotional image, which may suffer somewhat technically in order to create a feeling about the jewelry is required. Both methods are acceptable depending on the desired result. Using a specialist in jewelry photography is important and the necessity of using the right type of lighting and equipment, etc.

Gem Material: Historically Speaking...
Michael Coan, Chair of Jewelry Design at Fashion Institute of Technology
An historic survey of the prominence of gem material; the rise and fall of certain gem material - why some made it to the "big time" and some went the way of the Studebaker.
This was an historical view of gem material; sometimes less is good, sometimes more is better, sometimes a lot is worse. Putting gem material in an historical context is not always easy, but there are some guidelines to follow. If you have ever asked yourself, why is coral so highly prized in the Himalayan country of Tibet, we found out why at this lecture. A common sense approach to understanding the historical value of gems.

Cindy Edelstein & Frank Stankus
BRILLIANCE! Masterpieces from the American Jewelry Design Council
If someone asked you to create a jewel about water what would you design? How about "peekaboo"?
Attendees were treated to what two dozen master jewelers did to interpret these and so many more ideas when authors Cindy Edelstein and Frank Stankus shared the visual bounty of their book "BRILLIANCE! Masterpieces of the American Jewelry Design Council."
The AJDC is a non-for-profit arts organization comprised of some of our industry's most talented artists -- masters like Henry Dunay and Jose Hess, Michael Good, Michael Bondanza and Whitney Boin to fine
craftsmen like Kent Raible, Alan Revere and Falcher Fusager.
The book is a compilation of a decade's worth of their one-of-a-kind projects whereby each year a theme is chosen -- often one word or concept -- and each member spins their own interpretation in metal and stone.
The collection is a glorious love-letter to the art of fine jewelry. It's a study in beauty, theory, concept and interpretation. Many of the projects are fine jewels ready to be worn to a gala or even the office. While others are more abstract and less literally jewelry.
This collection was explored with the authors and their stories of the projects, the artists and the organization. Also explored were the concepts behind these beautiful jewels and more about the men and women who created them and thus a little piece of history in the process.

The Impact of Brazilian Gemstones in 18th century Jewelry Design
The history of jewelry is intimately attached to the history of the use of gems throughout times. As an example, the opening of the sea route to India in the 16th Century had a huge impact due to the more readily available gems produced in the Orient. The discovery of the new gem occurrences in Brazil during the 18th century, namely diamond, imperial and colorless topaz, amethyst and chrysoberyl, completely changed the concept of jewelry, resulting in the massive use of new coming gems and color. Due to the Brazil connection, Portuguese jewelry became unique and differs greatly from the European production of the time. In this presentation, we travelled back in time from medieval times towards the early 19th century, explaining how the new sources and trade routes affected jewelry design, with illustrations of magnificent Portuguese jewelry.

Mysteries of the Rainbow, Getting the Best From Your Spectroscope
Colin introduced the OPL spectroscope to the world 35 years ago in England, for his own students to fill an obvious gap in the range of entry level gem testing instruments and this original concept has blossomed over the years.This was an opportunity to get to grips with an instrument that most find intimidating at best and at worst impossible. Colin demonstrated in his own highly enthusiastic way, how to get the best from this much maligned and misunderstood instrument. Attendees came away wondering how they ever managed without this excellent piece of kit! Colin’s 36 years of teaching gemology to the coveted FGA level was well received.
‘A Students’ Guide to Spectroscopy’, a booklet produced by Colin & Hilary Winter, has all the techniques needed to master this instrument in detail, with full color illustrations of practically all of the spectra you are likely to see as a practicing gemologist. Even if you’ve never heard of this booklet, this workshop was an excellent opportunity to talk to the man himself; get up close and personal, ask questions galore, and even put him on the spot!

The Changing World of Gem Treatments: A Glimpse Beneath the Surface
New gemstone treatments continue to enter the market and it seems there is no limit to the types of treatments being used and the number of gemstone varieties involved. The results of many treatments are permanent but many are not, and we're finding an alarming number of surface treatments being applied to colored gemstones and diamonds alike. Some of the most troublesome include "fancy-color" diamonds that are nothing more than off-color stones with a surface coating on the pavilion; surface coatings on off-color topaz that can transform them into very natural-looking--and much more costly--"pink topaz" and "precious" topaz, as well as the popular shades of "blue" topaz; and cobalt-coated "blue" sapphire that is anything but blue! Attendees heard about these and other surface treatments, examine stones, and learned some easy techniques to spot them.

Dayton Simmons, Owner of Silver Day Trading
Turquoise: Natural or Otherwise
The presentation focused on the fact that well over 95% of all turquoise currently available on the market is not NATURAL, which is defined as turquoise that is hard enough to cut and polish as it comes out of the ground. This includes rough material, cut cabochons, beads, carvings and finished jewelry. The vast majority of said material has gone through one of several hardening processes to make it commercially viable. The group became aware of the various turquoise treatments, learned about discerning natural turquoise from treated material and had an opportunity to see and feel the difference. Dayton displayed many samples of turquoise from the different mines and the various treatments.

Dr. Rayner W. Hesse, Jr.
Jewelrymaking Through History
All art objects, whether they are paintings, pottery, sculpture, or any other media, represent the people who created them, and jewelry is no exception. Dr. Hesse spoke about jewelry making and jewelry usage, from ancient times to the present, describing the people, places, terms, and tools in the history of jewelry. Also he spoke about how the economic, geographic, political, religious, and social circumstances of a place and time influenced the materials that were used to make jewelry, the signs and symbols in that jewelry, as well as the way it was worn. More than just pretty pieces, jewelry often has great symbolism and tradition attached to it that is handed down through generations. Dr. Hesse brought samples and/or representations of the eras of jewelry making, focusing particularly on the jewelry of the last 200 years (as it is available and accessible). Members are invited to bring their own unique pieces to aid in the illustration and discussion.

Gary W. Bowersox, American Gem Trader, President, GeoVision, Inc.
Afghanistan Gems & Jewelry
The personal and professional adventure began about 32 years ago, when the intrepid Gary Bowersox went to Afghanistan to help develop its gem resources. The country had long been a producer of fine lapis, and exciting new finds were popping up fairly often. International demand for colored gems was also booming. So the future looked bright.
Then Afghanistan descended into hell. At first the government fought opposition from all sides, and finally toppled. In 1979 the Soviet Union invaded. After the Soviets left, equally fierce civil conflict spread and the infamous Taliban regime rose to power.
Through it all, often in great danger, Mr. Bowersox kept coming back - and gems ended up playing a positive role in the nation's history. Today, he is confident that gems can be part of a better tomorrow for Afghanistan and its people. In addition to buying and selling, he works with Afghan miners to maximize this important source of jobs and revenue.

Karen Rice, GG, Suna Brothers
Karen Rice, FGA, gemologist for Suna Bros. Inc in NYC conducted a lecture on Pink Diamonds for the Manhattan Chapter of the GIA-Alumni on November 19th at The National Arts Club. Suna Bros is one of the two American jewelry manufacturers to employ pink diamonds in their jewelry. The most rare diamonds in the world are red/pink diamonds. The only place they come from is the Argyle Diamond Mine in the remote NW Kimberly region of Australia. 10,000cts out of 30 million carats mined there are pink. It has not been officially determined which minerals and effects cause the pink color. The pink colors range in shades with the most intense saturations being the most rare. They can cost 10 times more than a similar colorless diamond. How perfect to have had this timely lecture after the Pink Diamond article in Gems & Gemology!

Donna Beaton, GG, Gemologist at AGTA Gemological Testing Center
October 16, Donna Beaton G.G., gemologist at AGTA Gemological Testing Center, spoke about padparadscha sapphire- the history of the colored sapphire, methods to define the stone, treatment, and its place in the market. The color of Padparadscha which means, "Lotus Flower", is presently defined as : pinkish orange to orangish pink; light to medium tone; low to intense saturation. This definition reflects the colors that can be found in Sri Lankan sapphires, where padparadscha has traditionally been from. They are also found in Madagascar and East Africa.
Of great concern now is a certain type of treatment called "bulk diffusion" which is not well received by stone dealers. The lab has learned how to test for these stones and has shared this knowledge with us.
