Small teal turquoise glass bud vase diamond pattern square

Pretty little glass bud vase in a turquoise blue color. Diamond pattern around the sides. Maker and vintage unknown. No defects noted (there are some dark spots in the photos that are reflections, and the inside is a bit dirty but I'm going to give it another cleaning). Measures 3 3/8" tall and 2 3/8" square. Smoke- and pet-free home.
