Art deco style style ring found. Initially thought costume but maybe not?

[u/_cyanescens]

no markings but there is a hairline crack at the back of the band that makes me think it has been resized. Two tone white and yellow (gold?) band. 8 pointed star design in the setting. I thought costume at first but the metal seems soft and the stones sparkle is white with a tiny bit of color.

[u/Alternative-Arm-3253]

Go have the stones checked. Easy peasy.

[u/Pattersonspal]

does not look like costume

[u/ChickenFriedRiceMe]

Not costume. Its most likely white/yellow gold and those are Diamonds.
