The ruby is considered one of the four precious stones, along with the diamond, the sapphire and the emerald. The name ruby come form the Latin term for red, ruber.
A ruby is a red gemstone whose shade varies between a light pink and a deep blood red. The price of a ruby is primarily based on the shade of the stone. The brightest and best colored red is called Pigeon Blood Red. A ruby of this caliber will be much more expensive then a lighter shaded ruby of the same size. The next factor in determining the price of a ruby is its clarity. Similar to diamonds, a naturally clear stone is of the best quality. Last but not least, the cut and carat size also determine the price of a ruby.
Aside from diamonds, rubies are the hardest natural gem, making them a practical everyday stone, as well as a striking stone for an evening event.
