Hello ! First I wanted to say that you do a great job at helping people with gemsona so thanks you ! I was wondering but do you have any idea of what kind of gem would be the fusion of a Hardystonite and a Sphalerite ? (sorry for my english !)
Sure thing, also thank you, from everyone here at gemsonahelp!
I would probably recommend a Grey Opal!
It shows a collaboration of neon colors found in a Hardystonite and the grey colors of a Sphalerite!
However, if you want one with more neon colors, then you can have a Black Opal!
I hope this helped!
