See below a couple of references you can use to be able to get a better understanding of the sizes for your jewelry.
Pearl Sizing Chart
Note: Use a cellphone or tablet to view the pearl chart. Get a dime and place it on top of our dime. Zoom in or out to match the exact size of your dime. Now you can get a true to size reference of your pearls.
Necklace Sizing Chart
Note: We also offer a Sterling Silver 3 inch extender in the chain category to help you get any extra length you might need.
Ring Sizing Chart
Note: Make sure when measuring around your finger you measure over the biggest knuckle and leave enough space for a ring to slide over smoothly.
