You seem like you have learned the basics of working with metal, but that’s only a portion of what it takes to make objects of beauty.
If you wish to prove your skill, create a gemstone amulet and show it to me. You will need to find and polish the gem, of course, and then you will also need to set it in metal. Pewter won’t do for this - you will need to use copper. Fortunately, both copper and gemstones are easily found in this area, so I am sure you won’t have too much trouble obtaining what you need.
