I Mined This Massive Mountain Of Gold To Find This Extremely Rare Gem

I knew there was an extremely rare gem to find and I wasn't gonna stop until I did. I set up an entirely new operation that runs faster and smoother than any before and kept grinding away until the new Onyx showed up. From there I decided to see what I could make with this valuable gem.
