Need help with biRP and URP

Hello there.
I repeat glow crystal from this topic in biRP and URP, and get very, very different results.

In URP+ShaderGraph i get result like on video:

But in biRP+AmplifyShaderEditor I get worse result. There is very very dark edges on crystal; and URP variand doesnt have it.

Can somebody explain, what the main problem? How can I achieve this result on biRP, or it is impossible/difficult?
