Handmade art glass vase, freeform shape with gold or maybe copper metallic flecks.
This looks to me like art glass made in China, not terribly vintage, maybe 10-20 years old? It's nicely made, and I love the swirls of smoke grey color on this piece - very different, a very modern neutral color scheme.
Measures about 7 3/4" x 5 1/4" x 4 3/4" overall. Condition is excellent, without damage.
