An Overview of Pearl-Testing Methods

Speakers: Elisabeth Strack, Gemmologisches Institut Hamburg

"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."

Black Gem Challenges

Speakers: Cigdem Lule, PhD, FGA., GG (GIA), DGA, Consultant, GemWorld International

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.

Separating Black Coral from sea fans and the treatment into "Golden" coral will be examined and participants will know how to easily tell them all apart. Examples of dyed Bamboo and Sponge Coral will also be available. A brief discussion of ethical and environmental pressures will round out the discussion.


Custom or Customize: What Does Your Customer Really Want?

Speakers: Kate Peterson, Performance Concepts

"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."

Gem Labs and Origin Determination: Past, Present, & Future

Speakers: Edward Boehm, GG, Raresource, Chattanooga, TN

"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."


Gemstone Quantification

Speakers: Sheahan Stephen, Sheahan Stephen Sapphires

This session will cover the methodology Sheahan Stephen uses to quantify gemstones. The constantly changing economic, political, cultural, religious, and environmental factors that keep the gem world fluid. Those along with the technical factors (treatment, origin, color, hue, saturation, clarity, shape, and cutting style) in hand with the supply and demand all play a role in the constantly changing gemstone prices. All these factors are taken into account and brought together to a delta which is the price.

Natural vs. Enhanced Lapidary Materials

Speakers: Helen Serras-Herman, FGA

"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."

Speakers: Dr. Lore Kiefert, Chief Gemmologist, Gübelin Labs

Practical Gemmology

Speakers: Alan Hodgkinson, FGA, Earth and Environmental Sciences

"The AGTA community is once again (for the 26th year), delighted to have Scotsman, Alan Hodgkinson share his observations and findings with those who are fascinated by gemstones and gemology. Mr. Hodgkinson is a seminar favorite who will inspire new students of gemmology and even enlighten the seasoned gemmologist. His book, Gem Testing Techniques, is now almost sold out, due to its straightforward practical applications of gem testing which the readers can undertake for themselves, many of them involving little or no expense.

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