2023 Assignment Modules

Assignment 1: Turquoise

Turquoise, long used for adornment, has been found in the ancient tombs of Egyptians, Persians, and Native Americans. It has been associated with the sky, life, and rebirth; some even see it as a stone of protection and good fortune. Today, turquoise is still revered for its beautiful color and is one of the birthstones for December. Recently, a team from GIA attended the Turquoise United conference in Albuquerque, New Mexico, where they had the opportunity to speak with several turquoise experts. Join us for discussions on modern turquoise collecting, fashioning, and treatment.

Assignment 2: Crater of Diamonds State Park

Crater of Diamonds State Park in Murfreesboro, Arkansas offers a unique experience to the general public. For a fee (US$13 for adults), anyone can search for diamonds or other minerals, such as amethyst, garnet, and agate, in a 37-acre field set aside for rock hounds. Any gems you find are yours to keep. This month, Dr. Aaron Palke, Senior Manager of Research at GIA Carlsbad, discusses the history and geology of this fascinating attraction.

Assignment 3: Photographing Color-Change Gems with Robert Weldon

Robert Weldon, director of the Richard T. Liddicoat Gemological Library, has photographed some of the world’s most extraordinary jewelry and gem specimens. His work has graced the pages and cover of GIA’s scholarly journal Gems & Gemology as well as other periodicals and books. Gems are known for the spectacular way with which they interact with light, but how do you capture their essence when they display different hues under varying light conditions? Peer through Robert Weldon’s camera lens as he discusses the challenges of photographing color-change gemstones.

Assignment 4: Pearls at the Tucson Gem and Mineral Show

With their soft, glowing luster yet staggering array of shapes and colors, pearls are truly unique in the world of gems. Their endless variety means there are pearls to suit all tastes and preferences. Rare, natural pearls have been treasured for millennia while cultured pearls are a testament to human ingenuity. A team from GIA was fortunate enough to chat with pearl professionals at the 2023 Tucson Gem and Mineral Show to gain insight on the current pearl market. Join us to see what they discovered.

Assignment 5: Miriam Kamau: A Woman in Mining

Dusty, hot, back-breaking work is how many people envision gem mining. It has traditionally been seen as “men’s work,” but more and more women today are entering the field and working their way up to the highest levels. One stand-out is Miriam Kamau. Starting as a “tea girl” in a gem dealer’s office, Ms. Kamau has, through perseverance and pluck, learned about gems and the gem trade, cultivated connections, and founded Mimo Gem Traders, where she serves as owner/director and operates a tsavorite mine in Kenya. Along the way, she has won numerous awards and worked tirelessly to reinvest in living improvements in rural Kenyan communities. She currently serves on the Board of Directors of the International Colored Gemstone Association. Join us as Ms. Kamau gives us a glimpse into her world.
