Many people associate its brilliant crimson colors with passion and love, making Ruby an ideal choice for an engagement ring. Ruby is the red variety of the corundum mineral species, while all other colors of corundum are called Sapphire. Fine rubies, especially Burmese stones over 3cts, are among the rarest and most expensive gemstones in the world. Prized for their beauty, durability, and rarity, it is the quality of the color which most determines the value of the stones. The ideal color is a highly fluorescent red of high intensity.

Ruby is mined throughout Southeast Asia. While Thailand and Myanmar (Burma) produce exquisite examples of this gemstone that the ancient Sinhalese people called "Ratnaraj," the King of Gems. This most sought after gemstone is available in a range of red hues, from purplish and bluish red to orangish red. Ruby is readily available in sizes up to 2 carats, but larger sizes can be obtained. However, in its finest quality, any size Ruby can be scarce. In readily available small sizes, Ruby makes an excellent accent gemstone because of its intense, pure red color - sometimes referred to "Blood red" Ruby from Burma or Myanamar.
