The birthstone for the month of July is a ruby. Rubies are commonly medium to medium dark vivid red or slightly purplish red in color.
Rubies are a variety of a mineral known as corundum. The gem is harder than any other natural gemstone, except for a diamond, making it very durable for everyday wear. The color of the ruby is the most important factor for its value. If it appears to be too light or has too much orange or purple to it, then it would be considered a fancy sapphire. A fine-quality ruby is rare. The ruby is said to ensure health, wealth, wisdom and success in love.
