The pineapple was the height of prestige and luxury in the 18th century. One could be worth thousands, so they would be rented - along with a security guard - until it was stinky and rotten. It was one of the more wild-looking foods brought back from the New World and Asia. Some people thought the spiky top of the fruit looked like a golden crown, so the monarchy jumped on the pineapple bandwagon. Charles II was so impressed with this pineapple/crown symbolism that he commissioned a portrait of himself being presented with one. During the Georgian era, when this ring was made, the richest people in England were beginning to grow their own pineapples. To create the light and heat required to replicate tropical conditions, people had to convert their already-expensive "orangeries" into "pineries". Whoever wore this ring might have been lucky enough to have seen a pineapple in person once or twice - maybe got a sniff? But did she ever get a taste? I can't say.
