- SIZE BEFORE YOU BUY: Smart ring sizing may differ from standard jewelry rings. Please use the size chart and sizing guide in the product images to measure the exact finger you plan to wear it on and confirm your US ring size before ordering. If you are between sizes, choose the larger size. If you are still unsure, please contact us through Amazon before purchasing.
