February 2026 GT Podicles
Two new GT Podicles are available. Check them out!
In GT Podicle #29, our hosts David and Jane explore one of the most diverse gem families; quartz, including its physical properties, the
numerous gemstone varieties, global mining locations, and offers guidance on gemstone care, synthetic identification, and market pricing.
In GT Podicle #30, David and Jane continue their journey looking at tanzanite, a relative newcomer in the gem kingdom, tracing its
history from indigenous Maasai legends to its 1967 discovery, the critical role of Tiffany & Co. in marketing the gem, and its market value, noting that
despite its scarcity, tanzanite remains more affordable than blue sapphire.
