A chance to mix gems and wine is on offer at The Goldsmiths' Hall on July 16. Sang de Pigeon: Rubies & Shiraz is a chance to hear from jewellery and gem specialist Joanna Hardy and wine-maker Michael Hall.

Hall and Hardy worked together as jewellery specialists in Geneva before Hall pursued his dream to become a winemaker in 2001.

Hardy will talk about her book Ruby: The King of Gems and the event will feature wine tasting of Michael Hall wines. Hardy is a liveryman of the Goldsmiths' Hall, a fellow of the Royal Society of Arts and appears on the BBC’s Antiques Roadshow.

Hall produces wine from 10 acres of vineyards in Barossa Valley and the Adelaide Hills in Australia.

The event is sponsored by Great Wine Estates and places are limited. The session at 3.30-5.30pm on July 16 includes canapés but places are very limited and offered on a first come first served basis. Please contact:
