RING SIZING
If you don't know your ring size, we offer - free of charge - an adjustable ring gauge. Just wrap it around your finger and line up the arrow to get your size - order HERE.  
Or if you'd rather, download the PDF, RING SIZER, print and follow instructions to find an accurate ring size before ordering.
BRACELET SIZING
Using flexible measuring tape, measure your wrist below the wrist bone. If you are between two sizes, select the smaller size for a tighter fit, or larger size for a looser fit. You can adjust bracelets about 1/4" smaller or larger.
If you don't have flexible measuring tape, you can use this paper version: DOWNLOAD A PAPER MEASURING TAPE HERE.
