Vintage Religious Enamelled Pendant - beautiful blue colours on it

USED - has marks and wear on the pendant. It does have markings on the back of it , but my old eyes can’t see or read that 🧐 This is vintage & I believe to be catholic but I am not a 💯 on either one. I did try and find the exact same one , but only found similar ones. Thank you for looking ! Religious Religion Pendant Charm Catholic Vintage
