The ornamental design for a jewelrychain, substantially as shown and described.
FIG. 1 is a front view of a jewelry chain showing my new design;
FIG. 2 is a rear view thereof; and
FIG. 3 is an edge view thereof.
The characteristic feature of my design resides in the combination of at
least one large mottle per link each large mottle surrounded by a
plurality of small mottles.
