Wondering how to make an iridescent and slightly translucent object? So I am trying to make a crystal in blender that has this kind of light translucency as well as iridescence within a certain color range. I'm pretty new to Blender so I'm sure it's something I'm just not very familiar with but I tried to kind of modify this video's method to not much success at dialing in the color of the iridescent range. This type of crystal is called Sunset Aura Quartz if you'd like to see other examples.
Here is a try (that works with both Eevee and Cycles), it's a mix between a Diffuse and a Translucent node, mixed with a Glossy that has a greenish color to get greenish reflects. Use a texture to get the streaks effect.

The image texture I've used:
