Majesty, mystery, allure, luxurious color and brilliance...these are the qualities that draw us to natural gemstones. Colored gemstones are enjoying a renaissance in popularity. Now is a fantastic time to begin collecting from the colorful world of gems.
Color is the most deciding factor in choosing a gemstone. In considering color, there are several components to think about:
Hue - basic color sensation: blue, red, green, etc. Plus blends, like purplish red and violet-blue. In some gemstones, like rubies and emeralds, having a true hue is more desirable. In others, a combination of colors, like blue-green in tourmaline, or violet-blue in tanzanite may be more desirable and will command a higher price.
Saturation - visual intensity. Imagine putting drops of orange food coloring into a glass of water. With one drop the water has a slight orange tint, or low intensity. With 50 drops in the glass, the water is obviously orange - we all this high intensity. The more saturated a colored gemstone is, the more expensive it is.
Tone is shade. Most gemstones should be at least a medium tone, but there are always exceptions. For instance, Aquamarine will never be a dark tone.
The most important thing to remember when choosing a gemstone - we are automatically drawn to the best. Each gemstone is unique and doesn't need to rank highest in the realm of technical characteristics to be beautiful to you.
