2024 GIA Digital Calendar
When looking at rough gem mineral crystals, there is often a fascinating world of geometric patterns and shapes that is erased when a gem is cut and polished. This year’s calendar explores the natural surfaces of gem materials using a microscopy technique call Differential Interference Contrast (DIC) in order to highlight the striking detail that often goes unseen in uncut gems. This year’s calendar is available only in digital format, allowing for immediate and no-cost access. Enjoy these images on your computer desktop all year long.
