Red Rubies | Gemstone Education

Rubies are among the most valued natural gemstones on the market, including diamonds, sapphires, and emeralds. The word ruby comes from ruber, the Latin word for red and connotes courage and emotion. A ruby is a pink to blood-red colored gemstone, a variety of the mineral corundum (a crystalline form of aluminium oxide). Legend has it the ruby is the gem of the heart with the power to light the flame of desire. It is the symbol of burning, everlasting love. Ruby is the birthstone for the month of July, the fifteenth and fortieth anniversary gem, and Cancer’s zodiac gem.

Like with diamonds, rubies are priced according to color, clarity, cut and carat. First, rubies are valued according to color. Pigeon blood-red rubies are the brightest, most expensive and rare of rubies. After color, clarity determines the price of a ruby. Similar to diamonds, clear rubies command a large premium. Rubies differ from diamonds, however, in that if they do not have any needle-like rutile inclusions, it may be assumed that they have been treated. Last but still important, cut and carat weight contribute to the value and price of rubies.

Rubies are a durable stone, suitable for everyday wear. They are incredibly tough as they are the mineral corundum and have a hardness of 9 on the Mohs scale. In its common form, corundum is used to polish other gems. To care for rubies, clean them with mild dish soap. Use a toothbrush to brush the stone all over, specifically in inclusions where dust collects.

James Allen has an impressive collection of rubies of all shapes and sizes. Rubies are most commonly featured in engagement rings as an accent, to compliment larger center diamonds. They also, however, stand on their own as striking, passion-infused stones.
