For millennia, blue sapphires have been revered by ancient civilizations such as the Greeks, Romans, and Persians.

2. Contemporary Significance

Symbolism Today

In contemporary times, blue sapphires are synonymous with royalty, romance, and luxury. The most notable example is the engagement ring given by Prince Charles to Lady Diana Spencer, now worn by Catherine, Duchess of Cambridge. These gems are often chosen for engagement rings and special jewelry pieces, symbolizing fidelity, sincerity, and nobility.

Modern Culture

Blue sapphires continue to be prominent in high fashion and celebrity culture, frequently appearing on red carpets and in high-end jewelry collections. As the birthstone for September, they are a popular choice for birthday gifts and commemorations.

3. Value Factors


Color is the most critical factor in determining a blue sapphire’s value. The ideal sapphire has a rich, velvety, deep blue to violetish blue hue with evenly distributed color and no zoning. Sapphires that are too dark or too light are less valued.


While inclusions are common in sapphires, clarity enhances value. Eye-clean sapphires, those without visible inclusions to the naked eye, are particularly prized. Some inclusions, like silk, can improve the gem’s appearance by adding a desirable velvety texture.


A sapphire’s cut affects its brilliance and overall appearance. Well-cut sapphires maximize the stone’s natural color and luster. Unlike diamonds, sapphire cuts are not standardized, and cutters often shape the gem to retain as much weight as possible from the rough stone.

Carat Weight

Larger sapphires are much rarer than smaller ones, with value increasing significantly with size. However, size should not compromise color and clarity; a smaller, high-quality sapphire can be more valuable than a larger, lower-quality one.


The origin of a blue sapphire can affect its value. Sapphires from Kashmir, Burma (Myanmar), and Sri Lanka (Ceylon) are highly prized. Kashmir sapphires, known for their cornflower blue color, are the most valuable, followed by Burmese and Sri Lankan sapphires.


Many sapphires undergo heat treatment to enhance their color and clarity. Untreated, natural sapphires are rare and command higher prices. Disclosure of any treatments is crucial to accurately determine the sapphire’s value.


Blue sapphires remain among the most desired gemstones, cherished for their deep, captivating color and significant historical background. When choosing a blue sapphire, consider the essential value factors: color, clarity, cut, carat weight, origin, and treatment. Whether as a statement piece, a symbol of commitment, or an heirloom, blue sapphires represent timeless beauty and elegance.
