Can't install Diamond Desktop Theme

I click the “Get New Themes” button and recieved a list of desktop themes. I selected the Diamond theme and clicked the install button but nothing seems to happen. When I downloaded it from their website and ran the install it said it installed but does not show up as an available theme to apply.
How do I get this theme to apply?

Normally you would extract to ~/.themes, then use the tweak tool to add
assuming your on SLED 12?

In general it’s;

icons → ~/.icons
cursor → ~/.icons
themes → ~/.themes
fonts → ~/.fonts
