Cousin Cornelia,I wasn't sure if I'd catch you before then, but in case I don't, I wanted to wish you good luck on your debut tonight.

I have no doubt that you won't fail to make a good impression. With your good pedigree and graceful manners, you're sure to be a success, but I do hope that you'll accept this gift anyway. I was told by the jeweler's that amethyst is supposed to bring the wearer good fortune, and while I'm hardly the superstitious sort, I thought it could bring you some comfort anyway — even if it's simply to complement your appearance for tonight!

Sincerely,
William
