Ruby, King of Gems

Rubies can command the highest per-carat price of any colored stone. This makes ruby one of the most important gems in the colored stone market. In its purest form, the mineral corundum is colorless. Trace elements that become part of the mineral’s crystal structure cause variations in its color. Chromium is the trace element that causes ruby’s red color and hence its’ difference from sapphire.

Color – Color is the most significant factor affecting a ruby’s value: Fine gems are a pure, vibrant red to slightly purplish red.

Clarity – If a ruby’s inclusions affect its transparency or brilliance they reduce the gem’s value significantly.

Cut – Rubies are commonly fashioned as mixed cuts, which have brilliant-cut crowns and step-cut pavilions.

Carat weight – Fine-quality rubies over one carat are very rare and the price goes up significantly as size increases.

Ruby, July Birthstone

Ruby is a pink to blood-red colored gemstone, a variety of the mineral corundum. Other varieties of gem-quality corundum are sapphires, which come in every color of the rainbow. The word ruby comes from ruber, Latin for red.

Ruby is 9 on the Mohs hardness scale making it a superior gemstone for jewelry. In fact, ruby’s rich red color is deserving of it’s nickname, the “King of Gems”.

The quality of a ruby is determined by its color, cut, and clarity, which, along with carat weight, affect its value. The brightest and most valuable shade of red called pigeon blood, commands a large premium over other rubies of similar quality.
