William Yeoward Crystal Fern Presentation VaseThe Fern Presentation Vase is an exceptional composition made by our cutting and blowing artists who have been specially trained in the different techniques required to produce this piece. The Fern engraving is a painstaking process because each small cut is made by holding the vase against the spinning copper wheel to make the tiniest notch in the fern leaf. The square base is very difficult to achieve as well.
