Once I was sure it would fit the ruby, I created a smaller cone of 0,5 mm sterling silver to be fit inside the outer one for the shoulder to carry the stone on. After a lot of fitting, filing and refitting, it was perfect and I soldered the two cones together:
After grinding the shoulders to a perfect sloped fit, I started working the ring shank. When I had hammered the 4 mm thread and started cutting it, I decided to split one of the ends into two and cut off bits and pieces along the shank to give it it's "grown" nature. Of cause that also meant quite a lot if filing...
Then a thorough annealing (the silver was VERY hard from the planishing)
Here the basic shape is finished.
Now I wanted to give it life, let it look almost grown, by adding the tube settings and balls of silver and gold. This part is enormously fiddly and so I forgot to take pictures along the way, but here I have finished all the soldering and filing and have just set the large ruby (sorry about the blurry picture).
The end result after oxidizing with LOS and polishing was sumptuous and very special indeed.
