If no preference is given, you will receive a 9" anklet.
If you don't know what size you need, take a measuring tape and wrap it around your ankle where you want it to fit. Then add 1/2" to that and you will have the size you need.
Please see shop announcement for current production/shipping times.
I also make this in all sterling silver https://www.etsy.com/listing/95679049/sterling-silver-hammered-heart-ankle
