Conclave 2026

This presentation is a 2-hour lecture and hands-on session.

Decisions, decisions—making an era call can be a tough decision, but it also shows your expertise. Suzanne and Starla have dedicated their professional lives to the forensics of jewelry dating. Part 1 of this 2-hour session covers the critical design elements, construction techniques, and materials available to create a set of factors that determine antique/vintage/reproduction jewelry dating. Part 2 is a hands-on session that has you using a checklist to "make the call" on a variety of pieces from the different eras. Working in small groups with your loupe, you will be able to test your knowledge. Then we will examine the pieces together in a "do you see what I see" wrap up, highlighting the key elements.

This Hands-on session will be repeated. Space is limited to 20 participants and is first-come, first-served.

This workshop will offer a systematic approach to grading gems for color, clarity, and cut. Various color systems will be discussed with actual hands-on grading of gemstones that I bring using the World of Color system. A methodology will be taught for assessing colored gemstones for clarity and cut and to gain experience in accurate pricing.
