|Resource Type:||Classroom Activities; Curricula and Instruction|
|Summary:||How do the natural shapes of gemstone crystals control what the final cut gem will look like? Where do gemstones come from? What makes them sparkle? Where do their colors come from? There's nothing as eye-catching as a piece of fine jewelry covered in beautifully colored gemstones. Natural gemstones, however, are simple mineral crystals whose chemistry and structure make them look special. Of the 2,000 minerals identified in the world, only about 16 yield important gemstones. To be a gemstone, a mineral has to be beautifully colored, hard, quite durable, and most of all, rare! Read and participate in this activity and learn about gemstones.|
