A good indication of how few fucks Rowling has to give is the amount she’s given to charity. I don’t see Rhys giving away 16% of his net worth any time soon. Someone could really use those four cents.To be fair, no one actually pays for their premiere jewelry if they're a somebody. Jewelers lend out expensive pieces ($50k earrings are the lower-mid end, believe it or not) in order to use stars as walking billboards. The clue is the fact that it's a currently-available collection with shoppable links right now. The pieces are insured, so even if something terrible happened to the jewelry, it doesn't come out of the famous person's money. It's no more theirs than a runway model's fashion show outfit is hers.
That's the kind of fame people like Veronica Rachel Rhys McKinnon can never even hope to achieve, for all his talk of sponsors. That is what real sponsorship looks like.
