They word ruby comes from ruber, latin for red. The color of a ruby is due to the element chromium. 

Ruby is a pink to blood-red colored gemstone, a variety of the mineral corundum (aluminium oxide). Other varieties of gem-quality corundum are called sapphire.

Ruby is one of the traditional cardinal gems, together with amethyst, sapphire, emerald and diamond.

Early cultures treasured rubies for their similarity to the redness of the blood that flowed through their veins, and believed that rubies held the power of life.

Ruby is one of the most historically significant colored 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.
Hindus divided ruby into four castes, calling the true Oriental ruby a Brahmin. Someone in possession of a Brahmin was believed to have the advantage of perfect safety.
Ruby has accumulated a host of legends over the centuries. People in India believed that rubies enabled their owners to live in peace with their enemies. In Burma (a ruby source since at least 600 AD—now called Myanmar), warriors possessed rubies to make them invincible in battle. They had to insert them into their flesh and make them part of their bodies.

Ruby has been called the most precious of the 12 stones created by God.
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. Many medieval Europeans wore rubies to guarantee health, wealth, wisdom, and success in love.
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.



The quality of a ruby is determined by its color, cut, clarity and carat weight. The brightest and most valuable "red" called blood-red or "pigeon blood", commands a large premium over other rubies of similar quality. 

Ruby is the traditional birthstone for July and is usually more pink than garnet, although some rhodolite garnets have a similar pinkish hue to most rubies. The world's most expensive ruby is the Sunrise Ruby.



Gem and mineral hardness is measured on the Mohs scale. 

Corundum (ruby and sapphire) is relatively hard—9 on the Mohs scale. It has excellent toughness and no cleavage, which is a tendency to break when struck. This makes it a great choice for rings and other mountings subject to daily wear. 

Corundum is stable under normal wearing conditions, which means it’s resistant to the effects of heat, light, and common chemicals. Boric acid powder will etch the surface of even untreated stones. Fracture-filled, cavity-filled, and dyed stones can be damaged by even mild acids like lemon juice.

Like any gemstone, a ruby may chip or crack due to blunt impact. This is especially true when mounted in a ring or bracelet.

Because rubies are very hard, foreign matter accumulates on surfaces, causing a faded or cloudy appearance.

Keep your rubies as clean as possible by applying lotions, perfumes and sprays before putting on your jewelry. Therefore, removing your ruby jewelry before performing gardening and household tasks is always advisable.

If your ruby jewelry is the victim of a hard knock, take it to a jeweller or goldsmith immediately and ask to have it checked under magnification for loose stones. If you wear your rubies regularly, periodic checkups are important in order to make certain the stones continue to sit securely in their mountings.

Avoid storing rubies in a container or bag with other gemstones. Place them separately in a soft fabric bag or lay them separately in a flat compartment to guard against scratching softer, more easily damaged gems and other polished gold items.

An occasional cleaning and minimal maintenance will keep your rubies bright and sparkling for years.



The best method to clean rubies and to eliminate dullness is to clean rubies by applying a mixture of mild liquid soap and warm water. Gently scrub your rubies and the jewelry mounting using a soft toothbrush. Rinse immediately with clean warm water and dry with a lint-free cloth for sparkling results.

Do not use common jewelry cleaner ,since these formulas may cause irreversible damage also on the setting if not used correctly.

Ultrasonic and steam cleaners are usually safe for untreated, heat-treated, and lattice diffusion treated stones.

Fracture-filled, cavity-filled, or dyed material should only be cleaned with a damp cloth.
