I often have custom requests for XLG heavy gauge charm holders, so have decided to list a few styles. My Turning Tide design will hold many standard charms...and is also perfect for rings. 

I do make multiples of these, but each one is hand bent, and no two are alike. I do not use jigs. 
I make them with .051 9.25 Sterling wire, which I hand stretch, cut, free form bend, and then hammer. You can see the hammer marks on all of my free form jewelry, I angle the hammer on purpose to let them come out. When the light plays over them, they will shimmer and reflect the colours around you.

Approx sizes is;
1 7/8 inch X 1 1/2 inch

I suggest a medium to heavy weight chain or cord if you will be adding many charms. (not included)

Gravity Held, not recommended for irreplaceable charms.
