The grand ducal ladies of Luxembourg are the absolute queens of wearing bracelets and necklaces as tiaras… and not always successfully. I’ve seen topaz, aquamarine, amethyst, that hideous large sapphire …
they look like what they are: not tiaras.
More successful attempts though: the diamond bracelet or necklace that is worn by the current Duchess of Braganza, the amethyst necklace Queen Silvia had made into a circlet, and sometimes the Wulfer’s tiara if it’s well integrated with the hairdo to hide the framework.

Another bad example from a recent New Years gathering
This time a bracelet I think.
In any case it looks awkward the way it is placed on her head

All,
I just thought I would try to start a tread with examples of what you might consider bad examples of necklaces turned into tiaras.
I think we rarely see good examples.
This is highly subjective and you might disagree.
But I thought it could be fun to see what you think.
