The English translation is wrong. "How many diamonds does the piece of jewellery/jewelery have?" Reported.
Yes, and I think another similar sentence also accepted "are in the piece of jewelry"
"How many diamonds are in the piece of jewelry?" was not accepted as of 28.5.2021. Reported.
'How many diamonds are in the piece of jewellery' should also be acceptable
Jewellery is the British spelling (jewelry is American, I think). I think just "jewellery" should probably also be allowed here?
This remains uncorrected
I agree with all these comments
This has still not been corrected
How many diamonds are in the piece of jewelry" should be accepted.
Also, "pieces of jewelry" are referred to as "jewelry" nobody says "pieces of...", it's just jewelry.
"How many diamonds are in the jewel is not accepted
