Hi there. Thankfully ring sizes are pretty standard and charts are available on the internet along with instructions on how to measure.
Woot: Could you please provide the total number of carats and also dimensions of the main prasiolite pear cut stone? Regrettably there is no information at all on the size of the gem used in the ring. Very pretty though & thank you for any additional information!
Hi there. Per the vendor:
13mm x 8mm
