It is in mint condition - it has no marks
Thank you for submitting your item for appraisal. This appears to be an art nouveau inspired pâte de verre vase of recent production. Most of these vases are manufactured in China or other parts of Asia today. The vase in your possession has an impressive size, but the supply of similar is high and it is basically a home decor item. The estimate is based on similar offered or sold at auction.
