RUBY

Ruby is one variety of the corundum mineral species, which also includes sapphire. Ruby is highly regarded and can command high per-carat prices. It is arguably one of the most important gems in the coloured stone market.

In its purest form, the mineral corundum is colourless. Trace elements that become part of the mineral’s crystal structure cause variations in its colour. Chromium is the trace element that causes ruby’s red, which ranges from an orangy-red to a purplish & pinkish reds.

The strength of ruby’s red depends on how much chromium is present—the more chromium, the stronger the red colour. Chromium can also cause fluorescence, which adds to the intensity of the red colour.

Ruby is one of the most historically significant coloured stones. Rubies are mentioned four times in the Bible, in association with attributes like beauty and wisdom. In the ancient language of Sanskrit, ruby is called Ratnaraj, or “King of Precious Stones.”

In the first century AD, the Roman scholar Pliny included rubies in his Natural History, describing their hardness and density. Ancient Hindus believed that those who offered fine rubies to the god Krishna were granted rebirth as emperors.

Ruby retained its importance with the birth of the western world and became one of the most sought-after gems of European royalty and the upper classes.

Desire for ruby is just as great today as it always has been. As a symbol of passion, ruby makes an ideal romantic gift. Consumers are drawn to the lush color because it also signifies wealth and success.
