Description and Characteristics

Ruby is the red variety of corundum, an aluminum oxide that owes its intense color to the presence of chromium in its chemical structure. Alongside diamond, sapphire, and emerald, it is one of the four traditional precious gemstones. It forms mainly in metamorphic rocks like marbles or in alluvial deposits. It is an exceptionally hard mineral, surpassed only by diamond, making it ideal for fine jewelry. Its color can range from orangey-red to purplish-red, with the "pigeon's blood" tone being the most coveted and valuable in the world.

Did you know...?

Its name comes from the Latin ruber (red). A ruby and a sapphire are chemically the same (corundum); the only difference is the color: if it's red, it's a ruby; any other color is a sapphire. In ancient times, Hindus believed rubies were "drops of blood from the heart of the Earth." Due to its structure, many natural rubies exhibit fluorescence under ultraviolet light, making them appear to glow from within as if they were on fire.

New-Age Properties

Ruby is known as the "sun stone" and the stone of vigor. It is deeply linked to the root chakra, stimulating vital energy (chi) and a passion for life. It is said to bring courage, confidence, and help overcome exhaustion or lethargy. Spiritually, it is a stone of abundance that helps retain wealth and passion in relationships. It acts as a shield against psychic attacks and promotes positive dreams, allowing the wearer to feel centered and connected to their personal power.
