At the bench: "BOXED" ring

After a long time... here is my new piece. I made it for the November challenge of the EtsyMetal team I'm a member. I'll try to participate in challenges as much as I can, it's a great way to refresh the designs and make new things.
The November theme was: Design with a letter.

I tried to "translate" the meaning of a word into a 3d object using the letters of the word. I created a box with sides made of the letters b-o-x-e-d  with a little copper flame trapped inside it. The ring shank is  square, to follow the style of the "boxed" idea.

On the bench:
~ I decided what  font I would use (I wanted something bold and steady) and then I made some draft paper models to check the proportions and size of the box.
~ During fabrication, it was a tricky task to file the silver precisely along the lines where the sides of the box would fold, so that they all would be at straight angles with each other. An accidental change of direction of 1 millimeter can affect the alignment drastically.
~ After soldering the box and making the shank, I connected them with a thick silver wire. As a final step I started to remove the extra silver from the box's base, happy with the way it turned out, but suddenly the whole box fell off. The reason is that the solder between the wire and the box hadn't run properly, so the bond was weak.  I must have used less temperature than needed and I had to solder them again.

a. I made very "basic" paper models to get an idea of the shape and size.  

b+c. Securing the sides of the box for soldering.  

d. The solder between the wire and the box was weak and as a result 
it broke later while I was removing the extra silver from the box's base.

I love how it turned out, and another one will soon be available in my etsy shop.
After making many light, curvy pieces, it was a nice change to make a bold, geometric object.

Riveted Ring with Chalcedony Druzy II

This is my second Icy Lake Druzy Ring, a little bigger than the first!

Except for the beautiful druzy chalcedony stone, the main feature of this ring is the use of rivets. I am very impressed with riveting, because it has so much potential both as an element of design and as a technical solution. Also I found the riveting procedure relaxing (after practicing a lot of times to find my pace)!

I want to use this technique in more rings and other kinds of jewelry.

To make it, I traced the druzy on a piece of paper and drew freeform shapes around it, for the base and the «cover» of the stone. When I was happy with the shapes, I sawed them from sterling silver sheet. I also sawed the ring shank and the bezel.

Next I filed and sanded everything. I prefer to file and sand the different parts before soldering, as it is much more easier to reach all the spots that afterwards may be hidden in narrow or awkward places.

After that I soldered the different parts together except the cover. I put the stone in the bezel and finally I riveted the cover on the top. This way the stone is protected and secured. Also it lets the light to reach the druzy from the sides.

If you make jewelry, what is your experience of riveting? What kind of pieces have you made? I'm sure the variety of riveted pieces is enormous!
