How to curl the edges of cuffs.
“I have made a thick ring shank with an 8mm jade set in a bezel. I was very happy with the end result. However, I would like to know how to make irregular edges on a ring shank or cuff that appear to roll upward or inward (not sure which is correct) See photo.”
Cuff by Ocean Girl, Leslie Shattuck.
The cuff pictured looks like reticulated silver over copper. Is this the type of edge that you are talking about? Those edges are probably curled by melting and/or curled with a little assist from round nosed pliers.
As far as anticlastic or synclastic curling, you should check out Creative Metal Forming by Betty Helen Longhi and Cynthia Eid. Also see Foldforming by Charles Lewton-Brain for other forming/forging techniques.

You can use a dapping punch shaft, rod or jump ring mandrel and hammer around that. Lubricate the form for easier removal. It would probably be easier to do this before shaping into a cuff or a ring. Lubrication can be beeswax, Bur Life solid, Liquid Bur Life or other types of lubrication.
You can use pliers – although, you might want to dip them in Plasti-dip or wrap with tape to protect the metal. Pliers can be utilized after shaping, of the cuff, is done but it will be more inconsistent and harder to control. If you shape after curling the edges, care must be taken to keep the curl from being crushed by the mallet. You can purchase pliers that have delrin jaws here, at Rio Grande. I don’t like the pliers with nylon jaws as I’ve found that the material breaks apart rather quickly.
Another idea, and probably the most permanent (while still being removable), is using thermoplastic to cover the tips of your pliers. I just found this thermoplastic sheet that might work well for covering 1/2 round and flat pliers. I have not tried this product yet but, I’ve ordered some to try out. You can create a cone (learn how in my video: How to Make a Cone.) for your pliers, from the sheet. I’d cut out the cone shape and then heat the plastic and then apply to the pliers. Rio Grande sells a Jett Ballistic Fixturing Compound, that contains Kevlar for added durability and strength. I have not used this product yet but, have also ordered it to try out. Rio also sells Jett Sett Basic which is a very durable and versatile tool for jewelers.
You can also use pitch and chasing & repoussé tools to create rounded/curled sides too.
Another method involves hammering a 90° angle on the edge and then “curling” that over by using the mallet.
I have a video: Fusing Silver and Reticulation on Copper that might help you to create reticulated silver on copper. Soham Harrison has a video on how to make a “wavy-edged” cuff that might help too: Wavy Edge Anticlastic Bangle.

Hope all of this info helps!

Shaping Cuffs with Bezels
Can you give me any tips and guidance in shaping a bracelet (cuff)? What kind of mandrel to use, how to solder or add embellishment to it? Are there any standard sizes ?
There isn’t one standard size of cuff – use whatever size fits comfortably yet, meets your design vision. Of course, there are common ranges of sizes but, widths can be varied. Here’s a link to a small chart of bracelet sizes at Jewelry Making Journal. Here is a link to a tutorial on making them.
