The 'Blue Diamond' ".....i got the blues - i'm gonna pack my things and go....." Folks with more than a passing interest in glass & glassworking around the globe will readily know that the best glass products are created by the 'Maestro's of Eastern Italy - famous names like 'Murano' are commonplace in major art galleries around the world as the pinnacle of glass quality & artistic excellence. Here at Diamond Bottlenecks we're delighted to announce our latest authentic glass bottleneck slide which we consider to be our very own pinnacle of quality & artistic excellence - The 'Blue Diamond'...a cobalt blue gem! We have secured exclusive rights to import these genuine, Italian-made soda-lime bottles, and proudly present here the finest authentic glass bottleneck guitar slide available in the world today. These fantastic bottles offer the slightly softer glass structure of our best-selling dark green soda-lime glass bottlenecks, but with the beautiful cobalt blue hue so desired by bottleneck / slide players.
