Vintage Simon Pearce hand-blown rectangular lead-free crystal vase - 1990s.
This is a substantial vase and well over 10 pounds. It has the ribbed optical glass paneling and the pontil and acid-etched signature on the bottom (see photos).
Simon Pearce no longer makes vases of this size and they are hard to find, especially at this price.
Measurements:
17 1/4” tall
6 5/8” rim
Since the item is hand-blown, measurements for the rim vary between 6 5/8” - 6 3/4”.
