We've all heard that diamond engagement rings are a relatively modern phenomenon (one we're all too happy to embrace, thanks very much), but did you know the iconic six-pronged solitaire was first created 130 years ago? The brainchild of Tiffany & Co. founder Charles Tiffany in 1886, the Tiffany Setting engagement ring has found its way to a million Pinterest boards (don't go denying it) and onto the fingers of those lucky girls with boyfriends who know the value of a little blue box.

To celebrate the 130th anniversary, Tiffany has created a campaign in honour of the artisans who painstakingly cut, polish and craft each ring by hand, using the same techniques that were first employed a century ago. Acclaimed photographer Martyn Thompson shot striking black and white photos of the artisans' hands at work, which are pictured with quotes from the jewellers themselves.

A 60-second black and white video delves further into the process, revealing that Tiffany rejects 99.96 per cent of the world's gem-grade diamonds and that its incredibly high standards go beyond the 4Cs to include a fifth - Presence - which grades a diamond's brilliance, scintillation and dispersion. Awaiting your own 5C-worthy rock? Now's the time to 'accidentally' send this link to your BF.
