Given the advertised price of these things, I'm not gonna break one! But in several photos you can see the octahedral cleavages within the crystals. I'm sure they are legitimately isometric / cubic - I just don't understand the orthorhombic habit!
Within the past year or so, there were four or five listed on minfind. Right now, just this one: https://www.minfind.com/mineral-649399.html (more rational prices have been in the realm of US$120-240).
Smash one and see if it breaks into octahedrons! That should prove the cubic-ness. 😆

Ouch. I look at xl prices these days and think that I can do an awful lot of micro-hounding with that much money.
For sure!
