Pretty in pink ring

I don't remember where I bought it, but I've had for over 10yrs for sure. Beautiful pink princess cut center stone with two clear emerald cut stones on either side. Bands 925 sterling plating has nearly all been worn off. Needs a good cleaning to return stones to original brilliance. Size is 6.25, 6 1/4. Settings are secure, no stones are loose. Lots of life left in it. Dont like the fading band? Buy it for the stones and create something new with them! Possibly CZ, but not marked as such.
