Citrine Pendant

I made this surprising, minimalist pendant as a Christmas present for Flic.

The fairly tight radius of the round-nosed pliers tended to mar the surface of the silver, so I should have used ring pliers or, better yet, made a hardwood press jig to joggle the arc profile in the vice. After a lot of adjustment I ended up with a symmetrical form, and removed the few dents with a little filing.

Next, I cut the pendant to length with a medium piercing blade and neatened up the ends with a file. 

I selected a 0.9mm square snake chain to echo the cross section of the pendant. I drilled a 1.3mm hole through the top to accept it. I then elongated the hole along the vertical axis with a ball burr. This allowed the chain to flow through more freely. Unfortunately, I forgot to take a photo.

I polished the pendant with wet and dry paper, followed by rouge on a felt wheel. 

Setting the stone was as simple as flexing the pendant between my fingers and slipping the stone into place. The stone does rattle a little. I toyed with the idea of adding a dab of shellac to fix it in place, but decided to stay true to the concept of the crazy setting and let mechanics do all the work. Ah! I could probably have laid a tiny leaf spring in the slot to push the stone up against the front face. A missed opportunity there.

Here's the finished item after a final polish and dip in the ultrasonic bath:

 Pretty pleased with this piece; I like the design, the experimental setting proved a success, and the whole thing even came together relatively quickly!
