This might be the way to go. Match plates should be easy to make on this small scale you would just need to make sure your item has enough draft to help it release from the sand cleanly.

I would check on the jewelry sites and see if any of them are doing sand casting and what mixture they use for the sand. There are several different recipes for sand depending on the metal being poured and I'm sure jewelry would call for some super fine sands and possibly some special compound additions. My father poured aluminum, brass and zinc all the time in his business and I made several of his match plates for his flasks. I poured aluminum a few times for him but I also know it has a lot lower melting point than the silver.

Here is a video you might find interesting

Actually for what you are making you would not need the two piece flask because the item is flat on the back side.
