Am I being unreasonable asking for jewellery to be valued during separation?

My wife and I are separating and trying to work through finances.

She wants to go through my business, bank accounts and everything properly, which I understand. But when I asked her to get her jewellery valued, she said I was being petty and that the jewellery is “for our daughters.”

I said I understand that, but everything we have built is ultimately for our daughters, and we still need to value the assets properly so the split is fair.

She then said the jewellery was gifted by me, and later said she basically doesn’t have any jewellery, which just made the conversation more difficult and made me second guess myself.

I’m not trying to take jewellery off my daughters or be nasty. I just think if we are valuing assets properly, then jewellery, watches, cars, business interests, cash and property should all be disclosed and valued fairly.

Am I being unreasonable for asking for jewellery to be included in the asset valuation?
