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.

Hidden Gem: Raluca Anghel, Communications @DPA

Every Monday The Carat Soup shines a spotlight on Hidden Gems: extraordinary women in our industry.Β  This week’s focus is on Raluca Anghel, who is in charge of communications at The Diamond Producers Association (DPA). This is a newly created role which sees Raluca direct external affairs and industry relations, based in London.

A crucial role at a time when we (as an industry as well as consumers) need clarity – pun intended – on varied topics from terminology to the gems we trade in.

DPA CEO Jean-Marc Lieberherr said, β€œRaluca’s collaborative style and strong communications background will make her an important asset not only to the DPA but to the industry as a whole.”


Anghel previously held roles at the European Parliament and before that, at Microsoft Europe.

Not-Quite-Au-Naturel: Scrunched Foreheads As More Undisclosed Synthetics Discovered

NEW YORK, USA – Gemolological Science International (GSI) findings, show undisclosed synthetic sapphires. The lab-grown melee was submitted as natural white sapphire, to the New York based lab. As part of the identification process in lab testing, each gemstone is thoroughly examined.

Consequently, there is not enough Botox in the world to hide our scrunched foreheads and furrowed brows. I had a sense of deja vu scrolling through the archive, as it was less than a week since this was published. The undisclosed submissions happen in labs across the world, from Antwerp to New York. Which begs the question: are more synthetics being submitted, or is technology improving enormously so there is a positive correlation? The more technology improves, the more synthetics (submitted as natural) are detected.

The lack of transparency has happened in the past with lab-grown diamonds and moissanite, submitted as natural diamonds. Check this out from 1997, winter edition. Fast forward to this, from 2017 winter edition. Twenty years later and it is still the same. This doesn’t seem like a long time, in an industry where we study, trade and enjoy gems that take billions of years to form. Yet I’m hopeful for further advances in the next 20 years.
