Silver ring hammerhead shark
Show your fascination with the intriguing world of marine biology with this silver hammer hair ring.
Adjustable from size 7.
We recommend adjusting the ring to the desired size and from then on limiting opening/closing to a maximum. Frequent opening and closing can lead to faster wear and cracking.
Measure your finger with a string to determine the ring size. For a wide ring, take one size larger, as it will not only go into the crease of your finger but also above it. (Rings may vary from the size chart by a few tenths of a mm).
