29 carat Sunstone Copper Bark Ring - Side View 2

This 29 carat Sunstone Handmade Copper Ring was made from 1/2 round 6 gauge copper wire.  The copper wire was wrapped around a ring mandrel twice.  I then bent each end of the copper wire perpendicular to the ring shank and trimmed each end to the proper length of the prongs that would be eventually formed to hold the Sunstone cabochon.  Using a jewelers saw, I cut/split the top and bottom ends down the middle to create left/right prongs.  I next tapered and shaped each prong with a file and sandpaper/sanding discs.  Just before setting the Sunstone cabochon, I soldered the two copper shanks together to give the ring more stability.  After setting the cab, I used a series of engravers to produce the bark texture.  A patina was applied to enhance the bark texture, then buffed for a final polish.  This Bark Sunstone Handmade Copper Ring can be found in my Muir Woods Collection, along with other copper and bronze rings set with a wide variety of large faceted and cabochon gemstones.

Handmade Scalloped Copper Bangle - Sea Cliff Collection by John S Brana

Handmade Scalloped Copper Bangle - Sea Cliff Collection by John S Brana

This Scalloped Copper Bangle Bracelet started out as a flat strip of 16 gauge copper sheet metal, 8 1/4 inches long by 1 3/4 inches wide.  I then formed the strip into a circular bangle and soldered the joint with hard Silver solder.  Next, the bangle was synclastically raised on a steel sinusoidal stake with a delrin mallet.  The fluting was produced by chasing the copper over a series of fluting stakes and annealings (8 in total), then plannished to remove any hammering marks.  After polishing, the Silver seem was copper plated.

Anticlastic Aluminum Cuff with Faceted Blue Quartz Gemstone by San Francisco jewelry designer John S Brana

This Aluminum Anticlastic Bangle with Blue Quartz Gemstone was made from 16 gauge aluminum sheet metal and anticlastically raised on a sinusoidal steel stake with a nylon hammer.  The aluminum was annealed several times to aid in shaping, then filed, and finally buffed to a matte finish before attaching the focal bead.  The Blue Quartz gemstone was fastened to the cuff by threading 14K gold-filled wire through the bead and wire wrapping it securely to each side of the raised cuff.  This anticlastic bangle, along with many more new contemporary jewelry designs, can be found in my SoMa Jewelry Collection.
