[Grammar] Which is THIS?THESE jewellery is a must have? URGENT

[esraaanwar]

Hello, So I'm having this dispute with my manager at work where I might get fired because of it. English is not our first language, but I've majored in English at Uni and I've taught it as well. He made me doubt myself on the other hand, so here goes my question:


We work in Social Media, so yesterday I posted a photo of 3 diamond bracelets, labeled them with numbers and wrote the following caption: Which of this jewellery is a must have?


He said it should be: Which of THESE jewellery is a must have?


I tried to explain that jewellery is an uncountable noun, and that "which" refers to the ONE bracelet that they should choose, and not the whole set, therefor it should be a singular and not a plural. I am not even good at explaining why things are the way they are, it just comes with sense.


So your thoughts are highly appreciated. It's ok if I am wrong, I just need to know because it's a big issue here at work. Thanks!

Welcome to the forum.

'Which of these jewellery' is definitely wrong. 'Which of this jewellery' is better but not natural English.

'Which of these jewellery items' or 'Which of these pieces of jewellery' are both better still, but as they are all bracelets, I'd say

'Which of these bracelets is a must-have?'

(Note: speakers of AmE spell it 'jewelry'.)
