MOST RINGS WE STOCK ARE IN USA WHOLE NUMBER SIZES WITH NO IN-BETWEEN HALF INCH SIZES. IN THIS CASE IT’S QUITE NORMAL TO ROUND UP TO THE NEXT HIGHEST NUMBER. BELOW THEIR IS A RING SIZE CONVERSION CHART, AND IS ONLY A GUIDE.
OUR BEST ADVICE TO YOU IS, GET YOUR CHOSEN RING FINGER MEASURED BY AT LEAST TWO REPUTABLE JEWELLERS BEACUASE THIS WILL PRODUCE A RELIABLE AND BETTER MEASUREMENT FOR CONVERSION.
OTHER THINGS TO REMEMBER ARE, THE WIDER THE RING BAND, THE BIGGER SIZE RING YOU WILL NEED. YOUR FINGERS WILL ALSO CHANGE SIZE BECAUSE OF BIOLOGICAL CHANGES, LIKE FLUID, OR BEING HOT OR COLD.
PLEASE BE AWARE THAT USING DENTAL FLOSS, PAPER, CARD OR STRING IS NOT THE WAY GET AN ACCURATE RING SIZE FINGER MEASUREMENT.
