Unidentified Quartz Crystal I Think

Hello, I recently acquired someone’s old rock collection and I found this, what I believe to be, quartz, but it’s unique. Under magnification you can see that there are very small inclusions of Hollandite in it and it is actually quite clear. There appears to be two colors in the crystal, gold and clear and it is almost iridescent when the light hits it a certain way. You see it reflect the colors of the rainbow. It’s a beautiful crystal and I would love to learn more about it. If anyone who knows anything about rocks and minerals can you please assist me with some insight? Thank you!
