Hello Abigail, I’m very glad that you chose Mearto for your online appraisal, Considering the photographs, overall pattern, glass quality and the colours, I concluded that this is a Bohemian Glass Style Set of three Bowls dating back to the period from 1970 to 1990. The set was enhanced by hand but by using electrical machines. So the cuts are executed by a person using a electrical carving tool. This kind of Bohemian style floral glass carving technique was very popular all around the world, especially in the Western market throughout the last quarter of the 20th century. It is likely made in U.S, very little likely that it was exported from Europe. The details of the pieces' decoration is notably different from the other pieces. The hexagonal hobnail pattern is one of the most interesting patterns observed on these period pieces. These pattern is made by molding techniques rather than carving. Pieces were multifunctional from salad bowl to sauce bowl to soup bowl as well as mixing bowls. The piece's hobnail decoration is referred to the head of a nail but visually it definetely resembles valuable stones and diamonds. Therefore it is accepted as a more elaborate and precious pattern. Quite decorative. The piece is in good conditon without visible problems. Partially Hand Carved Glass. Dimensions: Smaller Bowl: 4.5 Inches of Diameter and 1.5 Inches High - Medium Bowl: 5 Inches of Diameter by 2 Inches High - Larger Bowl: 9.5 Inches of Diameter by 3.5 Inches of Height. Condition: The piece is in good conditon without visible problems. Provenance: Unknown. 200-250$ for the set.
