As a boy I collected all kinds of semi-precious stones and things of the like. In my box of  treasures was this silver pearl. I made a pendant and presented it in the jewelry box I made my wife for Valentine’s Day.

Before I made it I did a few rust experiments. The results here.

Step 1: Initial polish

To start I cut a section of ½” pipe. This pipe is in the electrical section at the hardware store. Five feet cost me $2.00. I chucked it in my lathe and used 400 grit sand paper followed by 800, and 2000 to polish it.

Doing this will make it eaisier to polish towards the end.

Step 2: Cut the groove

The pearl is held within a groove by the tension of the metal. I based my measurements off the pearl which is about 6.5mm wide.

First I marked the pipe with marker. I followed that mark by scoring a line with a pipe cutter. Next I used a carbide bit to cut the initial groove. I expanded the groove with a round hobby file.

Step 3: Refine the ring

After cutting the ring free at the score line I filed off any rough edges left behind from the pipe cutter.

Safety First: Use extreme caution if you use a lathe like I do. You have to understand what angles are the safest when using a file on a piece that’s spinning at 2500 RPM. Just incase you hit the chuck you want it to deflect not get bound up. Always work within your experience.

Step 4: Open the ring

I located the seam on the inside of the ring and used wire snips to cut it open. Next I flattened it it out with a hammer on a hard surface. Make sure you don’t hit it too hard. You don’t want to mar it up.

This is cool and simple. I want to try it but I might cut grooves in the metal to give it some more texture.

No glue. It's held in a groove with just tension.

Awesome work
i was wondering where you get your chains that you put the pendants and things on
Mrballeng (author)  hrollinson2 years ago
The one shown is a silver box chain. I think I got it from Target for about $15.00. Though sometimes I use fashion chain which you can get at the craft store, 6' for $3.00.

Change of subject. In another of your 'ibles you said you used stainless paperclips. Where do those come from? I really like this pendant and your instruction are very complete and clear. Thanks.
Mrballeng (author)  stormy03142 years ago
The paper clips I use are just the common ones you find at any store. If I wrote that maybe you could let me know on which ible so I can correct it. Thanks for the comment.

Incredibly pretty and very sweet! Where did you get the pearl? I'm also curious as to how pearl would react with the metal, would it?
Mrballeng (author)  Kryptonite2 years ago
The pearl came from Sea World during the 1980's. I'll keep you posted on any metal pearl reactions.

Beautiful! Your wife is one lucky lady. :-)
Interesting idea you've got here!

How did you polish the inside of the loop where the ends meet?
Wonderful Valentine's gift! So beautiful!
