Okamite

I’m ready to write a wiki-style article, but I can’t locate a widely recognized mineral named “okamite” in standard mineral databases. If you have a source, a spelling variant, or more details (appearance, locality, chemistry, crystallography), please share them. Alternatively, I can create a concise, fictional wiki-style entry for a mineral named Okamite, kept under 300 words, with plausible sections such as etymology, occurrence, composition, structure, properties, and references. Which would you prefer?
