Marcasite Full Heart Stud Earrings.

1. Choose a ring you already own that fits the correct finger.
   
2. Use a ring sizer tool, or wrap a strip of paper/string around your finger base, mark where it overlaps.
   
3. Measure the length (in millimetres) of the paper/string and compare with a size chart.
   
4. When doing this, consider your knuckle size (if large, go a half size up so the ring passes over comfortably).
   

Tip: Measure your finger at room temperature (not too cold or hot), ideally at the end of the day when fingers are slightly larger.

* These values are approximate. Slight variations may occur between different designers.
