This listing is for a set of 4 vintage Baccarat Crystal White Wine or Brandy Glasses with a round stem although you could really use these for water, cognac, port wine, claret or anything else you choose to drink. They measure 5 5/8" tall, 2 1/8" across the top, 2 13/16 across at the bottom. Baccarat crystal is all handblown so there are minor variations from piece glass to glass including with the weight. These weigh from 3.5 ounces each to 4.6 ounces each. They are marked on the bottom "BACCARAT FRANCE" and might be in the Perfection pattern. The last picture is from Wikipedia and shows this glass being used for Sherry. These are in excellent condition with no chips or cracks, but 2 have very light scratches on the bottom of the bases. They have been extremely well cared for in the past. I inherited these in the late 1990s and they have been boxed up since then in bubble wrap. Please see the photos for more detail.
