Cristal de Val-Saint-Lambert
The Val-Saint-Lambert crystal glass tradition — the making and cutting of the prestigious Belgian lead crystal produced at the Val-Saint-Lambert factory (established 1826 at a former Cistercian abbey near Liège), whose specific deep-cut crystal patterns and high-lead-content glass produce the characteristic exceptional clarity and brilliance that made VSL crystal the most prized Belgian luxury object of the 20th century. The VSL tailleur de cristal reads the correct cutting depth through the same raking-light assessment as the Swiss watchcase (CRAFT-1289) but applied to the facets of a cut crystal object — reading the shadow depth that indicates the correct v-groove cut depth for the characteristic VSL deep-cut patterns.
