Diamond Jubilee is the daughter of Fancy Pants and Rarity

Diamond is Posh, Creative, Generous, Polite, Proud, Charming, and Dramatic she is the definition of a true lady but while she may be a lady that doesn't mean she's going to sit back and watch injustice being done to others, she is quick to defend if needed and helps host many grand events in Canterlot.

Both of her parents are always filled with pride of their daughter, she may be wealthy but she doesn't act spoiled about it Fancy is always heard boasting about his daughter as well as Rarity.
