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 10" tall vase is truly an exceptional piece. It's the tallest of the 3 available sizes in this style. It makes a great award with its high perceived value and pragmatic use possibillities.
