This is full lead (24%) crystal produced by hand in Europe (Poland) by experienced European craftspeople. The Medallion cut is a crisscross diamond cut topped with a wheat cut with one exception. There is an open, shield-shaped part of each piece that is left uncut to accomodate engraving (additional) which can make it a great trophy, corporate gift or presentation piece. We advise against laser engraving on lead crystal but other forms of personalization and engraving are acceptable. All cuts are highly polished. This 7.5" diamter bowl is the middle size of the three available sizes.
