Val st Lambert
Desirability comes in all forms and when that desire is glass I think you have to consider the work of the Belgium glass factory, Val Saint Lambert as one of the best.
The 1950s and 60s saw some of their most stunning art glass forms being made. The quality is exqusite, with organic shapes of rounded lobes and swirls and the depth of the crystal giving a quality of a calm of an arresting pool of water.
The colours, which I adore, range from pinks, greens and blues to crystal clear. To tell this unique glass apart from others you have to feel the incredible weight as a lot of lead is using in its manufacture.
If you only have one piece of art glass make it Val St Lambert.
