Help with ID-Pink and Green Glass

[luckyfinds1985]

Is the pattern diamond optic and is this  a juice glass? Which company made this? It stands 3 3/4" tall, diameter across the top is 2 5/8" and it holds 3 ounces of liquid when filled to the very top of the glass. Thank you in advance!

it is a diamond optic footed tumbler. most 3 oz were called cordials or canape cocktail (think oyster or shrimp). juices are usually 5 ozs. look up green and pink Tiffin glass to see if the colors look right to you, and what the use was supposed to be ..
