The "pink" is quite probably "cranberry" (gold ruby), and the process starts when a bud of gold ruby is attached to a blowpipe after being cut from a ruby roll. Milk glass is gathered over the gold ruby, and the piece is blown in a shape mould. Then it's stuck up on a punty, and the crystal edge is applied. Finally, it's crimped and cracked off. That rough punty mark suggests to me that it's likely European. This sort of thing was the inspiration for "Peach Crest" by Fenton Art Glass in the early 1940s, and I'm sure you can see lots of it on eBay, etc. (no punty marks on the Fenton pieces, however, as they were snapped up).
