Not everyone gets to be what they want to be all the time. Me? I am an actor. I love acting. I didn’t want to be a soldier. But I’m the wrong color.

Starburst quartz The inclusions of grey metallic haematite (an iron oxide, see http://tinyurl.com/nngtpnh) are overgrown with needles of rutile (a titanium oxide) in a gemmy quartz. The planes of rutile needles are oriented with the crystallographic growth of the quartz to produce a hexagonal pattern, revealed to great advantage in this freeform carved gem.

To most people, diamonds are the most valuable mineral, but to most geologists, that may be zircon. Even more than diamond, they really do last forever, being the oldest thing humans have yet discovered on Earth (see our older post http://tinyurl.com/k9668zp). They are also valuable to geologists in their time-keeping ability. Unlike diamond, and many other minerals, you can directly tell when it was formed by radioactive decay of Uranium into Lead. The combination of the durability and the time-keeping make Zircon useful to find ages of rocks even after they have been metamorphosed!

Let’s get down to Bismuth.

Bismuth (Bi) is a naturally occurring element with an atomic number of 83, chemically, it resembles arsenic and antimony.

As you can see in the image, bismuth crystals are quite obviously angular- this is because the edges of the rhombohedral crystal structure are more energetically favourable positions than the interior of the structure. As a result, molecules continually ‘build on’ the edges but don’t fill in the centre when crystallising. The higher rate of growth on the edges forms a crystal which appears to be partially hollowed out in a rectangular-spiral stair step design.
