I've bought a ton of other types of jewelry from her (bracelet cuffs, rings, bezeled pendants, etc) but I know she also does wirewrapping in solid 14k. And you can ask her to just do the pendant, no chain, to save some cash. I don't think she has any ametrine in her store but she is great about custom orders.
Also there is another etsy seller, her name is jenco I think ( I'll check to be sure). I used to look at her stuff a lot bc she uses solid gold with big chunky gems, and I used to see a lot of wire wrapped 14k things in her store, which was fairly unusual. Never bought from her though.
It looks like she has upgraded her technique to more of a riveting style bc I don't see much wire wrapping. But she's still working in solid gold so you could always ask her about a custom order. She has a lot of the type of gems I associate with wire wrapping - larger natural polished and chunky gems.
