Natural rubies are one of the most coveted gemstones, renowned for their vibrant red hue, which ranges from pinkish to deep crimson. Formed under intense heat and pressure within the Earth’s crust, these gemstones are primarily composed of corundum, a mineral that gains its rich colour from traces of chromium. Rubies have been treasured for centuries, symbolizing passion, love, and power. Their rarity, especially in larger sizes, adds to their allure and value. Often found in countries like Myanmar, Mozambique, Thailand, and Madagascar, natural rubies are frequently used in fine jewellery. Their durability, rated 9 on the Mohs scale, makes them suitable for everyday wear.
