I was there between 30 and 40 years ago, and there was no conveyor belt then. I remember pausing slightly a few times, and no one rushed me along. All I remember was a little ring that I really coveted. It was round and domed with tiny rubies in a cross form on a ground of tiny sapphires with a ring of more tiny rubies around the border. So pretty!
Hmmm, one of these? Though I think they’re all diamond-bordered.
I just came back after googling to claim my poor memory! I think the ring I saw was one of the Coronation rings – the one especially made for Victoria because she had such small fingers. It’s funny how memory plays tricks … I could have sworn the rubies and sapphires were much smaller and set pave style. It’s still pretty!
It is!
Pre-COVID, my local museum had an Egyptian exhibit, and they also said that everything except the mummy that was on permanent display were replicas. I personally felt a bit cheated.
I visited The Zoo of The Damned in Brazil. Horrible conditions, tiny cages. I’ll never forget the Black Jaguar they had. Cage was about 4x9 feet. The animal could just barely take one step and turn around. Poor Devil did this constantly, pacing back and forth while emiting the most mournful, pitiful wail I’ve ever heard. Saddest thing I can ever recall seeing. 
Saw a cage with some kind of crazy bird, about the size of a small turkey. It was sitting on a perch, looking really distressed and uncomfortable. Then, Plop! Out drops an egg! How about that??
It dropped off the perch, pecked it open and ate it, right in front of me.
They also had displays of the worst taxidermy ever.
