-Irina Jelavic Model Ring-
This ring is designed with Irina Jelavic in mind.
To express her femininity and alluring charm, it has been crafted as a delicate two-piece ring set.

Wear both for a flamboyant look, or one at a time for subtle elegance.
This special jewelry captures Irina's brilliance and strength, allowing you to enjoy it according to your mood.
