Lab grown diamonds have disrupted the jewelry market. Price and higher profit margins for retailers are contributing factors to their popularity.
Because not all lab grown diamonds are eco-friendly, we'll discuss the new standard of sustainability for both mined and lab grown diamonds through SCS Global Services. scsglobalservices.com
Lastly, we discuss how lab grown diamonds expand on the limits of some technology and the sky is the limit for it's many uses.

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. Biomimicry refers how science borrows from the natural world to create new technology.
My special guest is the immensely stylish and interesting Genevieve Hudson-Price, actor and jewelry designer born and raised in NYC. As an actor, she is best known for her work on HBO’s The Wire, The Deuce, and The Outsider. Her jewelry line, Blue Morpho Jewelry, is comprised of one-of-a-kind pieces handmade by Genevieve using recycled metals and ethically sourced precious materials—often featuring real butterfly wings and spider webs encased in hand-carved crystal and gold, as well as real beetles. All of her butterflies come from sustainable butterfly farmers—never hunters. Her jewelry is available is available at ABC Carpet & Home, her website is bluemorphojewelry.com.

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.
