A Visit to the Mines of Tajikistan: A Designer's Perspective

Tuesday September 15, 2026 9:00am - 10:00am EDT

High in the Pamir Mountains of southern Tajikistan lie some of the world’s most storied sources of spinel and ruby. For centuries these remote deposits produced gems that traveled along the Silk Road and ultimately adorned royal treasuries and museum collections. Today, new production is limited, but the landscapes and histories remain extraordinary. This talk shares a visual journey to the historic mining region of Badakhshan. Through photographs and firsthand observations, the audience will see the dramatic geology of the Pamirs, the locations of the famous mines, and the immense physical challenges of extracting gems in such rugged terrain. For anyone fascinated by gems, geology, or the human stories behind them, this presentation offers the next best experience to standing there yourself.

Secret Teachings of a Gem Buyer: Field-Tested Techniques for Unlocking Value in Estate Jewelry

Tuesday September 15, 2026 2:30pm - 3:30pm EDT

Olympic A

As wealth transitions from baby boomers to the next generation, more estate jewelry is re-entering the market, often with rare gems unseen for decades. For jewelers and gem professionals, that creates both opportunity and risk.

This session combines practical gemology with real-world buying strategy, sharing field-tested techniques from high-volume colored stone acquisition. Attendees will learn how to assess value efficiently, spot subtle indicators others miss, and avoid costly mistakes in the estate space.

Using applied examples, unconventional tools, and observational methods, this session sharpens instincts for fast-moving buying environments and equips professionals to approach post-consumer jewelry with greater confidence, clarity, and commercial awareness.

Casting 101 for Non-Casting Jewelry Professionals

Tuesday September 15, 2026 4:00pm - 5:00pm EDT

Olympic A

Understanding the lost-wax casting process is critical for everyone in the jewelry ecosystem – even if they are not bench jewelers or in a casting shop. This session will illustrate the process from design concept to metal. We will touch on pattern creation, building a mold and spruing the jewelry, ceramic investments, kiln firing, and, finally, casting into the alloy of your choice.

Highlights for non-casters will include some key “laws of physics” when it comes to what is possible in casting precious metal alloys, how to design for casting success, recognizing the best manufacturing methods for a design, and spotting potential problems in finished jewelry.

Luminescence – A Hugely Underrated Physical Property in Gem Testing

Wednesday September 16, 2026 10:15am - 11:15am EDT

Olympic A

For many in the gem trade, luminescence is nothing more than the observation of the glow that gemstones exhibit under a UV lamp used in gemology, with limited use such as the distinction of natural and synthetic spinel. But fluorescence is a property of much more importance used in a wide array of applications. In the past three decades a large variety of luminescence-based gem-testing methods have been developed, from imaging to spectroscopy using all sorts of excitation sources. Today, luminescence-based testing is extensively used for diamond testing but also for a wide range of other gem species such as corundum, spinel, beryl and many others. This presentation offers an insight into the world of gemstone luminescence, with amazing images, surprising science, and convincing results.

What Every Jeweler Should Know About Precious Metals Metallurgy

Wednesday September 16, 2026 3:00pm - 4:00pm EDT

Olympic A

While jewelers are trained in karat, color, and metalworking techniques, many would appreciate and benefit from a more in-depth understanding of metallurgical principles and the properties specific to the precious metals they work with and sell every day. Knowing the underlying concepts will illuminate issues that are common at the bench, at the sales counter, and in the customer’s long-term satisfaction.

This presentation explores precious metals metallurgy, the mechanical properties of various jewelry alloys, the impact of casting techniques on quality, and the anatomy of common casting defects. Additional highlights will include the metallurgical impact of various bench techniques and tips for using your new technical knowledge at the sales counter.

Designing Jewelry for Casting Success – From Concept to CAD to Efficient Finishing

Wednesday September 16, 2026 4:30pm - 5:30pm EDT

Olympic A

Computer Aided Design or “CAD” offers infinite design possibilities and invites infinitely small detail, but we can’t lose sight of the laws of physics and material science! A design looks great blown up on the screen, but how will that detail translate to metal?

This session will provide clear guidelines for casting success as we discuss best practices for: minimum wall thickness, casting holes, dimensional tolerances, shrink rates, feature radius, differences in metal flow by alloy, hallmarks, finishing access, and the dreaded “Zoom of Doom” that could mislead anyone into thinking you can cast 0.01mm features.
