A single article limit is fairly standard for most insurance companies although, from having a quick look at websites, my €1,000 guess was a bit low - seems that €2,600 or 5% of contents sum insured (whichever is greater) is fairly standard as a single article limit. There may also be a limit on what % of contents value can be 'valuables' - e.g. with Hibernian the payout on valuables can't be any more than one-third of the contents sum insured - so if contents are insured for €30,000, no more than €10,000 can be on jewellry, paintings etc.
