For centuries people were confused as to what the gem tourmaline was. Until the development of modern mineralogy it was identified as some other stone, such as a ruby, sapphire, emerald, and so on because of its coloring.
It’s easy to understand why people confused the tourmaline with other gems: Very few gems match the gem’s dazzling range of colors. From rich reds to pastel pinks and peach colors, intense emerald greens to vivid yellows and deep blues, the breadth of this gem’s color range is unrivalled. Brazilian discoveries in the 1980s and 1990s heightened tourmaline’s appeal by bringing intense new hues to the marketplace. (http://www.gia.edu/tourmaline-history-lore)
Soon the gem was identified in the late 1800’s in California and it was known as the American gem by the Tiffany gemologist George F. Kunz.

Red Ruby

red ruby

Ruby is the most valuable variety of the corundum mineral species, which also includes sapphire. Rubies can command the highest per-carat price of any colored stone. This makes a ruby one of the most important gems in the colored stone market. Chromium is the trace element that causes the ruby’s red, which ranges from an orangey red to a purplish red. (http://www.gia.edu/ruby)

The redness of the Ruby comes from how much chromium is present or absence. The more chromium the red is brighter and the less chromium the lighter the color. The color is what makes the ruby so unique. The color red seems to catch people’s attention even if it’s a lighter red.
