How do doublets or triplets fare in one of these? Badly?
At first I was thinking of opal doublets/triplets, which I would assume wouldn't do so well because even a triplet has exposed opal on the sides, and it's the vibration, not the liquid, that causes the problems anyway.
As I thought about it more (my grandmother had a garnet doublet she always called a "ruby doublet"), I realized the bonding zone between any doublet/triplet layers might not get along so well with an ultrasonic cleaner...

Exactly my thoughts.
I'll also add, because this happened to a friend about two weeks ago after she bought her own ultra-sonic cleaner and popped a bunch of her diamond jewellery into it:
Check the settings as well.
Several of her pieces came out with diamonds missing. Obviously not well set to start with and the vibrations popped the stones out.

That's also happened to her with a ring bought from the same jeweller. A large ring set with rows of princess cut diamonds that literally exploded out of the ring when she was clapping at some function she was attending. She only managed to find about half of them. As you can imagine, she was not a very happy camper.
I am very surprised. I have been myself around those ultra sonic for at least 20 years in my parent's store and after my husband's store. Never had this problem. I never heard about problem with diamonds jewells.
That is strange. Maybe the new ultra sonic instruments "ultra sonic" too much?

Holy crap, that's terrible. I hope she's no longer patronizing (matronizing?) that jeweler!
While this jeweler may well be at fault, do not be so quick to blame. I have seen many rings with the prongs so worn only the crud underneath the stone was holding them in. Once the crud is removed of course they fall out.

Zircon can be brittle. I wouldn't recommend ultrasonics or steam cleaners. I've also noticed something peculiar with zircon over the years. The facet edges tend to abrade even on the pavilion of the stone which is suffering no apparent abrasion.
Spinel is tough and durable. Of course it is possible to stumble on one which has been fracture filled and could be compromised with ultrasonic or steam cleaning.
