Making a ring with tube-set stone continued

25 helmikuun, 2021 //  by taavasblog

In my earlier blog post discussed the beginnings of this project. One of our learning assignments this past month was a half-round band with a faceted stone set in a tube.

The measurements in the band were off, because I melted my first two rings. I run too hot I guess.

Ring with the over-sized tube. Remember to keep the tube length longer in order to contour file the bottom as well as give yourself some room for error on the setting.
  • Silver ingot. Notice the break in the bar from an uneven pour
  • First shape with square mill
  • Pulled wire
  • Shaping the wire into rings
  • Brushing the flux
  • Soldering with hard solder
  • Polished rings
  • Stamped rings
Phases of silver from ingot to stamped ring.

I decided on a sapphire because of its hardness, and also because it was the only stone in my discount baggie that came even close to the 3.0 size. The stone was 3.1.

Our measurements for the task were 3.0 diameter round wire, tube with 1.0 wall thickness and stone of 3.0 diameter.

  • Tube shank with solder filed away.
  • Trying to create a new lip on the tube
  • Squashing the tube with rolling mill to create a new lip
  • Using the clamp vise to create lip.
  • Tube became tear-drop shaped, which fortunately did not hinder the setting process.
  • Making sure the tube is in the center of the ring shank.
  • Checking that the tube fits the ring perfectly and does not protrude form either side. note the mark where I’d like my setting to sit.

I sawed the ring shank after soldering, and used a ball burr to widen the gap.

Filing down the tube.

I used couple of different setting tools, but I liked the burnisher and brass punch with hammer the most. The punch setting is really just a square piece of metal that is used with hammer to push the metal on top of the stone.

Notice that in tube setting the metal should not touch the facet edges, otherwise it doesn’t give the setting the rounded look.

All in all I’m happy with the piece, and with the learning that took place.
