Impossible. Ravenclaw's diadem is said to have been 로스트 for ages. Muriel's tiara was kept in her home. Besides, while Ravenclaw's diadem is described to have the House 모토 engraved on it, it is not said to be goblin-made. While Muriel's tiara is.
Either when they were at Hogwarts for it, 또는 when Ollivander goes to Muriel's I started thinking 'hey, that tiara's been passed down in a pureblood family that wasn't always bloodtraitor material for a long time, right?' Guess not, but oh well, it was still a cool hidding place. And how Harry walked right past it once before? Tss... Just goes to show how little details aren't always so little.
