Xylem - silver plated pendant and necklaceThe Xylem necklace is a dramatic and stunning design that shows the cross section of the xylem vessels in a plant stem. These bundles of tubes help the plant to take up water but they are hidden from our view and it isn't until they are cut through in a thin cross section and stained with dyes that light up the structures that the true beauty of these cells can be appreciated. The pendant is sealed using a deep layer of resin to protect the design.
