@@treasury3624 i feel i should point out that Number 8 is just a darker shade of Smokey Quartz often referred to as 'Cairngorm' or 'Morion' Number 6 is a Herkimer diamond, the photo at 2:52 is actually Fluorite and not Quartz, the photos of Number 2 (blue quartz) is synthetic man made stuff (proper blue Quartz is opaque and very very rare, number 1 is usually called Aura Quartz and is also synthetic..and i can't believe you didn't include the most beautiful variety which is Ametrine (Amethyst with whisps of Citrine running through it!)
Blue quartz has inclusions of either magnesio-riebeckite, dumortierite or indicolite. It's extremely rare since it only naturally occurs at a couple places on earth, with material from Antequera apparently being the best in the world. Although the stuff in this video is most likely fake.
