The ruby, a gemstone synonymous with passion, protection, and prosperity, holds a distinguished position as the birthstone for July. Revered throughout history and celebrated for its vibrant red hue, the ruby is considered the king of precious gemstones. This article will explore the ruby’s history, geological origins, gemological properties, and cultural significance, drawing exclusively from available sources.
History and Lore
The ruby’s history is rich and deeply intertwined with human civilization. Sources indicate that rubies have been prized for centuries, symbolizing power and courage. While specific dates for early discoveries are not detailed in the provided materials, the ruby’s enduring appeal is evident in its historical presence within royal regalia and religious artifacts. The ruby is a variety of the mineral corundum, closely related to sapphires, with its distinctive red color stemming from the presence of chromium.
The value of a ruby is directly linked to the intensity of its red color. The most highly sought-after rubies are those exhibiting a “pigeon’s blood” hue – a rich, deep red with a subtle hint of blue. This particular shade has long been considered the benchmark for ruby quality.
