Rubies and Sapphires from Eastern Africa, A chance or a nightmare for conservation?
TUCSON CONVENTION CENTER: MARICOPA ROOM 9:00 AM - 10:00 AM
Vincent Pardieu, GG, VP Consulting SPC, Field Gemologist & Consultant, fieldgemology.org
Beginning - Intermediate - Advanced

The Eastern African region from Northern Mozambique to northern Kenya and including the island of Madagascar is world famous for its wildlife. But it is increasingly also becoming famous as the world main source for colored gemstones. Some of these such a Tanzanite and Tsavorite are found nowhere else on Earth, but it is also increasingly becoming the World main source for rubies, sapphires.

Rubies were first discovered near Longido in Tanzania at the beginning of the 20th century. Since then many other discoveries took place first mainly in Kenya then in Tanzania in Madagascar and in Northern Mozambique. It seems obvious that the dynamic will not stop and it is likely that other important discoveries will happen in the coming years. These gems will provide many opportunities for the gem trade, but many challenges also will come, one of them being illegal gem mining in areas dedicated to conservation...

During that presentation, Vincent Pardieu, who visited regularly most of these deposits since Summer 2005, will present the history and the dynamic of the ruby and sapphire trade in East Africa and its perspective for the future.

TUCSON CONVENTION CENTER: GREENLEE ROOM 1:00 PM - 2:00 PM
Kate Peterson, Performance Concepts, www.performanceconcepts.net
Beginning - Intermediate - Advanced

Seems that the whole industry is talking about 'custom' these days - but what are we really looking at? No doubt - a special piece of fine jewelry - particularly bridal jewelry - represents a highly individual expression. One of the most important factors influencing purchasing decisions for today's fine jewelry buyers is the ability to customize. Is there a difference though between 'customize' and 'custom'? Does the drive toward personalization mean that you need to invest tens of thousands of dollars in software, equipment and payroll hours building a 'custom shop' just to meet consumer demand?

In this presentation, you'll learn how to ask the right questions to help determine your customers' real interest, while you assess your business model and consider strategies for capturing a bigger share of the 'customized' market.

There is a false idea circulating that the Scots are a mean race. However Alan will demonstrate just how mean a gemologist can be.

 
Modifying Hand Tools for Fun and Profit
TUCSON CONVENTION CENTER: GRAND BALLROOM 3:30 PM - 5:00 PM
Charles Lewton-Brain MJSA
Beginning - Intermediate - Advanced

It's no secret that bench jewelers love their tools—the more tools, the better. It's also no secret that they like to modify their tools—maybe to create a cut not easily achieved with a stock tool, to access unusually deep recesses, or simply to make the tool easier to hold and handle. Whatever the reason, a standard bench tool rarely stays that way. In this session, Charles Lewton-Brain offers some of his favorite modifications. Learn how to expand your tools' capabilities.

Moderator:
- Dr. Laurent Cartier (Gemstones & Sustainable Development Knowledge Hub)
Beginning - Intermediate - Advanced

This seminar brings together panelists from science and practice to discuss how the gemstone industry can further contribute to sustainable development. Colored gemstone supply chains are globalized and highly fragmented at the same time.

The industry and researchers can contribute to overcoming some of these gaps, by bringing together existing knowledge and targeting critical research issues in coloured gemstone mining, manufacturing and sales.

The seminar will also consider the recent establishment of a Gemstones and Sustainable Development Knowledge Hub at the University of Delaware, and discuss the training and expertise needs of the industry on these issues.

 
An Overview of Pearl-Testing Methods
TUCSON CONVENTION CENTER: MARICOPA ROOM 9:00 AM - 10:00 AM

Beginning - Intermediate - Advanced

Pearl testing involves three main tasks: recognizing imitation pearls, cultured pearls and natural pearls. distinguishing saltwater and freshwater origin and beaded from non-beaded cultured pearls.

While standard methods like a microscope or an ultraviolet lamp still play a role, more advanced instrumentation has become a prerequisite. X-radiography, first used in 1929, has meanwhile developed into high-intensity digital microfocus radiography and X-ray computerized tomography that delivers three-dimensional pictures.

EDXRF (Energy Dispersive X-Ray Fluorescence) is a spectrometric method that allows to distinguish saltwater and freshwater origin by determining the presence of manganese.

Gem Labs and Origin Determination: Past, Present, & Future
TUCSON CONVENTION CENTER: MOHAVE ROOM 1:00 PM - 2:00 PM
Edward Boehm, GG, Raresource, Chattanooga, TN, edward@raresource.com, www.raresource.com
Beginning - Intermediate - Advanced

Gem labs, gemological equipment, and testing techniques have evolved greatly over the past century. In the early days of origin study there were far fewer sources and treatments to consider so the gem testing equipment and techniques were less advanced but required expertise that only a few gemologists had mastered. New sources and treatments have put continuous pressure on laboratories. In response, subsequent generations of gemologists and research scientists have been forced to develop more advanced equipment and testing techniques to meet the constantly changing challenges.

Edward Boehm is a colored stone dealer and consultant from Chattanooga, Tennessee. He began his gemological studies in Switzerland where he spent the summers of his youth under the tutelage of his Grandfather, Edward Gübelin, piquing his curiosity in crystals and gems. Upon graduating in Geology & German from UNC, Chapel Hill, he went on to obtain the Graduate Gemologist diploma from the GIA in 1988, followed by the Certified Gemologist title from the AGS in 1996. He also completed the SSEF advanced laboratory gemology course under the tutelage of Prof. Henry Hänni in 1998. He was recently awarded an honorary FGA from the Gemmological Association of Great Britain.

Examples of dyed Bamboo and Sponge Coral will also be available. A brief discussion of ethical and environmental pressures will round out the discussion.

 
Black Gem Challenges
TUCSON CONVENTION CENTER: MOHAVE ROOM 9:00 AM - 10:00 AM
Cigdem Lule, PhD, FGA., GG (GIA), DGA, Consultant, GemWorld International, clule@gemguide.com, gemguide.com
Beginning - Intermediate - Advanced

Identification of black gems pose a challenge for the gemologist and the buyer as they are sold with little or no disclosure of their nature. Recently, black diamonds are increasingly seen in high end jewelry. This lead to other black gems to be used as an alternative in many forms. There is no doubt that artificially produced black materials such as black paste and ceramic dominate the mass market. Dr. Lule will talk about the most common black gem materials encountered in jewelry production and discuss practical techniques of recognizing them.

 
Natural vs. Enhanced Lapidary Materials
TUCSON CONVENTION CENTER: GRAHAM ROOM 1:00 PM - 2:00 PM
Helen Serras-Herman, FGA, www.gemartcenter.com
Beginning - Intermediate - Advanced

There is an endless inventory of lapidary gem materials on the market today created or enhanced to look like some other natural material, usually one that is rare and expensive. Most are natural materials that have been dyed or compressed to simulate a better quality material, or another natural material, while others are partly natural stone and partly other materials, such as resins, metals, etc. All these simulants provide an inexpensive alternative to natural gems, and many of them are beautiful, with bold patterns, and durable to be used into jewelry. The only problem surrounding these stones is the lack of disclosure, as the cabochon and bead market almost slides quietly under the disclosure radar.

Helen Serras-Herman, gem artist and FGA gemologist, will discuss various natural vs. enhanced lapidary materials; among them the popular Sonora chrysocolla, natural turquoise vs. compressed blocks, sugilite vs. Mohave purple turquoise, drusy gems, azurite with malachite, lapis, and rainbow calsilica.

 
Who's Afraid of Freehand Sketching?
TUCSON CONVENTION CENTER: GREENLEE ROOM 1:00 PM - 2:00 PM

Exploring Ultraviolet LW/SW testing of gemstones
TUCSON CONVENTION CENTER: MARICOPA ROOM 1:00 PM - 2:00 PM
Lily Faber, FGA, EG, Gem-A
Beginning - Intermediate - Advanced

Although not always a diagnostic tool, UV light is often the 'forgotten' essential in a gem testing. It is one of the easiest of tests to perform, providing a portable, quick solution and used in harmony with additional hand held instrumentation in everyday gem testing – for loose and mounted gems and jewelry.

Lily will be exploring, with discussion and 'hands on' practical, what fluorescence is all about - the circumstances where it can most effective, its correct use and interpretation of results - as well showing you some really cool fluorescent effects along the way.

 
Appraising Carved Gemstones
TUCSON CONVENTION CENTER: MOHAVE ROOM 1:00 PM - 2:00 PM
David Craig Rotenberg, ECGA (AGS), GG (GIA), CAPP (ISA), SCM (NAJA), Owner & Expert Appraiser - David Craig Jewelers, Langhorne, PA
Beginning - Intermediate - Advanced

This lecture will take the participant on a tour through the world of gem carving as an art form. If you were asked to appraise a Picasso, would you value the paint, canvas and frame? Of course not, it's a Picasso! The paint, canvas and frame might contribute to the authentication process, but nothing more. So it is in the world of gem carving. The skillful carvers invest 600, 800, or even 1000s of hours of labor, in addition to the cost of the gem. This is art and needs to be treated with the same esthetic. Be prepared to learn an appraisal methodology that may be different and will definitely challenge your thinking strategy.
