Structural color and biomimicry are the subjects of this episode, and the blue morpho butterfly is a featured player in both. Structural color is how light interacts with the nano surface of a material - like a blue morpho butterfly wing, or the exoskeleton of an iridescent beetle.

Artisanal small-scale gold mining, shortened to ASM or ASGM, has workforce of 20 million and produces 16% - 20% of the gold annually! ASGM is also the largest global user and emitter of mercury. Mercury has been used for thousands of years to extract gold, but the way miners use it produces low yields of gold, and miners don’t know the risks of using it. My guests in this episode are working to formalize ASGM toward ethically mined, responsibly sourced gold with the purpose of reducing or eliminating the use of mercury while also addressing issues of health and safety, human rights, the environment and, public awareness.

Barney Barnato was brilliant in business and...he was fun. He was the magician at the dinner party, the boxer in the ring, the actor on the stage. He was a fearless entrepreneurial thinker who regularly pushed in all his chips to move his business interests forward. Barney's first job was as a street performer in London. He heard about the diamond rush in Kimberly, South Africa from his cousin, and ten years after arriving to the diamond fields owned a vast financial fortune in the largest diamond mine in the world. My special guest is Nancy du Tertre, who discovered through her research that Barney was her great, great uncle.

The Three Brethren jewel (seen on James VI and I hat) was one of the most important jewels of the Middle Ages. Designed as a men's shoulder clasp, the jewel was named for 3 perfectly matched balas rubies, a term that predates gemology meaning red gemstones. In fact these gemstones were red spinels. Ruby and red spinel weren't gemologically differentiated until the 1800's. The red spinels weighed about 70 carats each. Indeed, The Three Brethren jewel was a spectacle of large gemstones and also included 4 large pearls, and a 30 carat pyramid-cut blue diamond from India known as the Heart of the Three Brethren. The jewel was owned by dukes, kings, queens, and one of the richest men who ever lived, Jacob Fugger. Then in the 1640’s the jewel disappeared without a trace.

In this episode of Gem Connection we discuss ammonite, an ancient squid-like creature that lived over 400 million years ago and survived three mass extinctions. We'll relate it to my favorite ancient Greek coin minted by Lysimachus, one of the Alexander the Great's top generals, and then to the Fibonacci Sequence.
