I'm about 90% certain this gem can only drop when you extract the vein perfectly. That might not apply when you get it as a bonus gem - which ii think i might have done? But the only verifiable times i've gotten these it's been when i did a perfect extraction.

They're still not guaranteed, i think it's just that they only have a chance upon a perfect mining extraction.
