This Piano Finish Rosewood Display Base has a Soft Circle Velvet Top, Making it Ideal for Displaying Crystal and Glass Vases or Trophies. It Instantly Adds a Higher Perceived Value to your Trophy Award or Vase. * When selecting your optional base, we recommend sizing up for the top felt diameter. Due to the nature of mouth-blown manufactured crystal, the base sizes of some of our crystal pieces may vary slightly. To ensure a proper fit, please select the base whose top felt diameter is the next size up from the base size of your crystal piece (rather than smaller or exact fit).
