The window itself was executed for the house of Joseph Briggs in Jersey City, New Jersey. Briggs was one of Louis C. Tiffany's most trusted workman and is the person who is often credited with these obscure glass and pebble confections. The crystalline pebbles of the border and the central clusters are arranged and graded in such a way as to make the semi-precious stones transcend into almost jewel-like qualities. In the past these rare pebble works were considered more of a curiosity, an eccentric offshoot of Tiffany's core business. However, very recently serious Tiffany collectors have snapped-up a related window and an orientalist dream of a table lamp both of which were sold through Sotheby's.
This detail from the Briggs window shows the subtle grading and tonality of the stone selection. This was no small feat and was achieved through the craftsman's adept skill and slight-of-hand as the tiniest "pebbles" forming the center are actually rendered in faceted-glass effortlessly blended into a cohesive composition. This blend of faceted-glass and pebble work is seen most closely in the Sotheby's lamp noted above. While the result does not suit all tastes the survival of these decorative oddities stand as a testament to Tiffany's genius.
