Hello, really looking for some advice here please.
I'm almost ready to send off my first batch to the assay office to be hallmarked. All the relevant forms are complete & the 10 year registration & makers punch etc paid. I saw someone on here saying to send in a batch of atleast 50 items in at a time, to help spread the cost through each item, however, there's a little more advice I'd love to hear on the following things:

Which courier would be best to use to get the box of silver jewellery to the assay office or do you just use the post office?

With necklaces, do you send in the pendant on it's own to be hallmarked, or do you send it with the chain attached - as a complete necklace?

Items with set stones (gems, etc) - do you set the stones into the bezels when they come back from the assay office or again, do you send these in as complete items with stones already set & all?

Any advice would be appreciated, look forward to reading the suggestions =)
