"A new auction record has been set, with today's sale of ..." We've all seen these headlines in recent years, so what does it mean to you and me? Join GIA London as they welcome Russell Shor, GIA's Senior Industry Analyst, for an informative overview of the importance of the world's auction market sales of gemstones and jewellery.

Shor will share his knowledge and expertise of the global diamond and gemstone trade, including details such as: in the past 20 years more diamonds over 50 carats have been mined, cut and sold than in all the previous centuries together. Why?

The majority of these mega-diamonds come, not from new sources, but from traditional mines like Cullinan/Premier South Africa and the reopened Letseng Mine in Lesotho. Shor will explain how the new mining and recovery techniques spare these large diamonds from the crushers and, ultimately, how they are sold - often for millions of dollars - at the world's top auctions.

Exchange ideas and inspiring conversation with others ahead of the talk, which starts at 6.30pm.

This event is being held by the GIA (Gemological Institute of America). Established in 1931, GIA is the world’s foremost authority on diamonds, coloured stones and pearls. A public benefit, non-profit institute, GIA is the leading source of knowledge, standards and education in gems and jewellery. For more information visit
