The vacuum is not necessary here, something this simple is achievable with sand casting (search for "Delft Clay") and a bit of practice. Ensure the sprue is wide enough and air channels are plentiful, make sure the metal is as hot as it's possible to get it, and pour swiftly in one fluid motion.
The snag is that you need about 3X your desired weight in metal, which in gold is... probably more expensive than the vacuum casting setup! So maybe the above applies mainly to silver unless there's a good use for the rest of the gold.
- ryaan_anthony 2y agothis is what i did! it cost me less than 100 bucks in supplies and just under 2k in various gold (14k-18k) i bought on ebay. i mixed in enough 24k to bring it up to 42 grams of 18k. i cast two sets of rings (11g + 2g) and had some leftover gold to recast into grains to share with our parents and future children.
