Gift from my Grandmother

This frosted pink glass decanter set (with 6 glasses) was given to me by my grandmother about 10 years ago. She claimed the set had been given to her by a friend. My grandmother, had she lived, would be 105 this year. I have no idea when she came to possess these items. All of the glasses are marked France on the bottom (see photo). The decanter, while the same exact design has no markings. I just brought it out "of hiding" and put it on the buffet in the dining room and it looks so pretty! I've been curious about the history of this glass but have not been able to find out anything about it. I love the wonderful colors in the decanter and the glasses. If anyone knows anything about the style, or the history please share. Many thanks.
