The pieces are made of borosilicate glass which has a melting point of around 1200 ºC, (diamonds burn at a temperature of about 800 ºC). The glass blower introduces the diamond into the viscous glass mass and places it in the desired position. The Diamonds in Glass website has a video of the process. Prices start at around 1620 euros for a small glass. Check out the gallery below for examples including the most expensive Champagne glass I have ever seen.
