hand blown glass goblets, large wine or water glasses amethyst w/ clear glass stems

Set of 10 hand blown glass goblets, amethyst glass bowls with crystal clear glass stems. These are nice and big, nearly 8" tall, and they hold 16 ounces comfortably. All are in excellent condition without damage or wear.

These are not marked or signed that I could see - maybe made in Mexico, or maybe made in China. They are obviously hand crafted, there's slight irregularities such as small bubbles or flakes of soot to some. I'd say at a guess that they're 15-20 years old, but can't be certain of their age, sorry.
