I got this vase at an estate sale some years ago. I looked online for something comparable but didn't see anything even close. There is one "rare find" cone shaped vase 25 cm (9.8") tall for $150!
This vase is 28" tall, 9" across at the top, 6" across at the bottom. Made in Poland sticker. Weighs a bit over 8 lbs.
I tried a few ways to get a good image but the clear glass is challenging. You're welcome to take a look in person.
