Ruby is known as the king of gemstones because of its rich red colour, rarity, strength, and long association with royalty and power. For centuries, rulers and warriors valued rubies as symbols of courage, protection, and authority. Its deep red shade comes from the presence of chromium, which also adds to its brilliance and value.

Ruby ranks 9 on the Mohs hardness scale, making it one of the hardest natural gemstones after diamond. This durability makes it ideal for jewellery that lasts generations. High-quality rubies are rare, which increases their prestige and price in the global market.

Across cultures, rubies have been linked with passion, energy, confidence, and leadership. In astrology, ruby is connected to the Sun and is believed to boost self-belief and success. It is also the birthstone for July.

Major ruby sources include Myanmar, Sri Lanka, Mozambique, Thailand, and Madagascar. Because of its beauty, symbolism, and scarcity, ruby continues to hold its title as the most royal and respected gemstone in the world.
