In GT Podicle #33, our hosts David and Jane talk about turquoise, a gemstone valued for millennia as a symbol of luck. They discuss its
geological formation, and its copper-heavy chemical structure. Next, they explain the historic and modern sources, such as Iran and the south-western
United States, while outlining specific physical properties like its waxy lustre and opaque transparency. Finally, they look at common enhancements,
the production of lab-created alternatives, the impact of limonite inclusions on market value, and essential care instructions.
In GT Podicle #34, David and Jane take a comprehensive look at the geological formation, historical lore, and global distribution of opals, primarily focusing on Australia’s dominant role in the industry. They explain the scientific theories of opalization and the specific physical properties that define these ‘stones of mystery,’ such as their unique diffraction of light. They also focus on the mining techniques, the emerging markets like Ethiopia and the rigorous classification of opal varieties, distinguishing between precious, common, and fire opals based on their body tone and optical patterns.
