The Gem and Mineral Show

Yesterday, I stopped by the gem and mineral show at the Exhibition Center in Factory 7. The Naviron Adventure school hosts the show every year and invites dealers, traders, collectors and specialists in the wonders of the earth to show off their wares. Although I have never really been interested in gems or minerals, I decided to go to ask an expert about a small mineral collection that my grandfather gave me when I was a child.

While at the show, I was lucky enough to meet a specialist who was willing to look at my collection and tell me about each mineral, including the name, classification and history of how it was formed. I discovered that minerals often begin their lives as gases or liquids, and are transformed into a crystalline structure through evaporation, high temperature, or intense pressure. Minerals are classified either by their physical or chemical properties. Physical properties define characteristics such as how shiny or dull the mineral is, how hard it is or how it splits when it is broken.

Chemical properties define what chemicals make up the mineral.
The show contained many examples of minerals that had been cut and polished to create beautiful gems. Diamonds, rubies and sapphires are just a few of the gems dealers had on display. Seeing all of these gems and minerals reminded me of the matching blocks in the Gamestar arcades.

Today, I decided to experiment with the idea of using gems and minerals in some of my games. To start, I matched up the colors of the blocks with the colors of some of the gems and minerals I had seen at the show. For example, I used the red block as a ruby, the green block as an emerald and the light blue
block as a sapphire. Then I made a multi-level game where my player was challenged to mine these gems from a dangerous underground cavern. It worked out so well, I think my next game might be about a diamond robbery!
