This is a set of four (4) red, cut to clear, Luminarc, Cristal D’Arques, cordials or liqueur stems. I believe they were manufactured in the 1960’s, by a company named J.G. Durand.
Three of the four are in excellent, used condition. One has a tiny chip on the base. I smoothed it down, and took a photo so that you can see. Make sure to look at the pictures.
