Vintage Materials - Red coral, black pearl, and 14k gold
Normally red coral is not a material I would feel comfortable purchasing or using. There is no sustainable deep sea coral. However, when a vintage supply comes up, I categorize it with my fossils... which is to say, ok to use in a good enough project, so that it lasts, and is not carelessly lost or destroyed.
So here's part of a very small amount of red coral I came into, with some also-vintage small black pearls. Wired with 22/14k gold filled wire, and solid 14k links. Just this one pair.
