Then I rough cut and formed the filigree in a batch, and then went through and did the fitting and adjustment.
I had to do very little cutting at this point. I then soldered that on. This was my first go using paste solder for some of the filigree. I used medium, and it worked very nicely. See my previous post if you want a bit more of my musings on soldering. Though I will say that that post was a bit too optimistic. I had to re-fire most of my second batch, and I still managed to melt a jump ring.
On to that, I made jump rings for the bails and attached those last. It went really quickly, all things considered, in two batches of five.
The final necklace is strung with agates. The original (at The Met) had glass "paste" beads. I couldn't find glass beads the right size and shape, and I really struggled to find anything that would fit the late Roman empire, but I have multiple written sources that site agate being used in jewelry, so I was happy to find the beads that I have.
