Reddit mentions of Jewelry: Concepts And Technology

For me silversmithing means large objects like vases and bread baskets. I'm just assuming you mean silver jewellery making. If it's jewellery making you are talking about, this would be a really good book.

It's not that easy to do. Which may be why you don't see much information out there. I more or less adapted techniques for metal to metal inlay from Oppi Untrachts book, Jewelry Concepts and Technology.
This is the only attempt I've made and I would consider it moderately successful at best. It was a collaboration and the lapidary told me the stone was black jade. It was not. So it wasn't really hard enough but you can't quite see the cracks in the picture.
You need a high speed water cooled diamond stone carving tool to cut your desired pattern in the stone with a slight undercut at the edge of the pattern to retain the gold which should be high karat and very soft.

I'm not sure about that book, but I'm willing to bet the original commentor meant this one instead: https://www.amazon.com/Jewelry-Concepts-Technology-Oppi-Untracht/dp/0385041853

Absolutely fantastic and massive book covering a very vast array of concepts, history, etc.

That’s the single most informative book I’ve had. Tim mccraight has a little beginner book that’s used a lot too, but it’s less in depth.

If you’re interested in a specific branch of jewelry (enameling? Casting? Stone setting?) there will be books for those too with more info, but Oppi is a good place to start.
