Problem with environment reflection on jewelry

[Luvanimation]

...didnt work for jewelry

It can be the model...
It can be the material you've used...
It can be incorrect use of the IBL's...
It can be a combination of the above...

Can you share your scene...?
If you want us to help you better, you should share the scene or a part of it, enabling us to give it a spin and see if we can make it look more like you want it to...

managed to get the result
