Netflix and Chilling with Diamonds

Last year, on 28 November 2019, Netflix released a documentary about diamonds, as part of Vox’s Explained series. A 23 minute summary of our (billion years to present day) industry.

With well known names and faces featuring in the show and voicing their expert opinion. Remember reading about Karen Smit (link) on The Carat Soup?

When asked about the pressure under which diamonds form, Smit the GIA Research Scientist said: β€œIf you think of 80 elephants standing on your big toe, that is the pressure that is equivalent to five to six gigapascals.” What a visual!

Other topics discussed include diamond formation, demand for diamonds, the current retail environment and of course the inevitable topic of lab grown diamonds.
