the dragonfly company: recommended sizes for copper jump rings

...a glimpse of the past inspiring treasured heirlooms of the future...

The

On this page you will find the jump ring sizes that we recommend for our copper jump rings. Please note that these weaves have been tested using our copper jump rings, and due to variations in springback these recommendations should not be assumed to apply to jump rings made by anyone else or jump rings made from any other metal.

As the copper jump rings are tested, the results will appear on this page. Copper 1.0/3.5 makes a beautiful Byzantine Chain in copper alone, and also makes a stunning Byzantine Chain in a mixture of sterling silver and copper, both using jump ring size 1.0/3.5. For the mixed metal chain, the “boxes” were made from sterling silver and the connecting pairs were made from copper. You could, of course, reverse this. 1.0/2.92 makes a beautiful Jens Pind’s Linkage, very slightly denser than the sterling silver equivalent, but still gorgeous and fluid.

Please note that the jump ring size is denoted by the diameter of the mandrel used to make it.

WEAVE	RECOMMENDED COPPER JUMP RING SIZES (in mm)
Barrel Chain	1.0/3.5
Byzantine	0.8/2.75 (delicate), 1.0/3.5 (mid-weight) - a very popular chain, 1.25/4.25 (heavy-weight), 1.6/6.0 (really chunky)
Dragonscale	0.8/3.175 with 0.8/4.7625 - absolutely gorgeous 1.0/3.5 with 1.0/6.0 - quite a statement
Enigma	1.0/3.5 - very stylish
European 4 in 1	1.0/3.5 - fluid and very comfortable (mid-weight)
Full Persian 6 in 1	1.0/5.5 (1.0/5.0 is too tight in copper, although it works well in sterling silver)
Half Persian 3 in 1	1.0/5.5
Half Persian 4 in 1	1.0/5.5
Helm Chain	1.0/3.5 with 1.0/6.0 (also known as parallel weave)
Jens Pind’s Linkage (JPL3, or JPL 4 in 1)	1.0/2.92 (mid-weight) - just gorgeous! 1.25/3.5 or 1.25/3.75 (heavyweight) - 1.25/3.75 is looser and more fluid than 1.25/3.5 1.6/4.75 - super chunky and fabulous!
JPL5 (or JPL 8 in 1)	1.25/6.0 - a variant of Jens Pind’s Linkage (JPL3) more intricate than JPL3 - fluid and VERY gorgeous!
Kingsmaille	1.0/6.0
Pheasible	1.0/2.92 - beautiful and delicate
Rhinos Snorting Draino	1.0/3.5
Romanov	1.0/3.5 with either 1.0/5.0 or 1.0/5.5
Shaggy Loops	0.8/3.175 1.0/3.75
Viperscale	1.0/6.0 - an intricate weave that is well worth adding to your chain maille repertoire!
