January 2026 GT Podicles

Two new GT Podicles are available. Check them out!

In GT Podicle #27, our hosts David and Jane explore one of the ‘new’ super heavyweights in the gem industry, tourmaline. Not only does it come in a wide range of colours but it also includes the prestigious and highly prized Paraíba Tourmaline that commands prices that up until recently were only seen in diamonds, rubies, sapphires and emeralds.

In GT Podicle #28, David and Jane continue their journey looking at some of the key players in the gemstone industry. This time, they look at peridot, a gemstone that Cleopatra was said to have had a deep affection for yet one that is often overlooked by gem buyers.
