Microscopy and Photomicrography

with Billie Hughes FGA

The day will start with a journey into the centre of gemstones and the features that gemmologists can see with a microscope. Billie will present the audience with an overview of gemmological microscopy and discuss the most suitable lighting conditions for a variety of scenarios. This will include examples of frequently overlooked features in gems and how to spot them with appropriate lighting setup. Then we will provide an overview of how touse Lotus Gemmology’s Hyperion inclusion database, an online resource withover 1,000 inclusion photomicrographs with a strong focus on ruby, sapphire, and spinel. Attendees can search Hyperion to learn how to separate natural and synthetic gems, treated from untreated material, and gain an insight into origin determination.

During the practical session, each delegate will be provided with their own workstation, complete with microscope and varied lighting to look at inclusions and learn more about what they can tell us about gemstones. We will also discuss techniques that can be used to capture photomicrographs. Attendees will learn how to take photos through the microscope, whether with their own cell phone cameras or with a professional photomicrography setup.
