When it comes to gemstones, few are as highly revered as the cornflower blue sapphire. With its vivid blue hue reminiscent of the delicate cornflower, this sapphire has captured the hearts of collectors and enthusiasts alike. But what exactly makes the cornflower blue sapphire so special? In this comprehensive guide, we will delve into the origins, characteristics, and factors that influence the value of this extraordinary gemstone.
What Is a Cornflower Blue Sapphire?
Cornflower blue sapphire is a specific variety of the mineral corundum, which is composed of aluminum oxide with trace elements that give it its color. The term “cornflower blue” refers to the gemstone’s distinctive and highly sought-after shade of blue. Unlike other sapphires that can range from light blue to deep indigo, cornflower blue sapphires possess a vibrant, medium blue color with a slight violet undertone, akin to the petals of the cornflower plant.
Origins and History of Cornflower Blue Sapphire
The history of cornflower blue sapphire is as rich as its color. These gemstones have been treasured for centuries, especially in ancient Persia and India, where they were believed to protect their wearers from envy and harm. The most renowned source of cornflower blue sapphires is the Kashmir region in India. Discovered in the late 19th century, the Kashmir sapphires set the standard for what is considered the perfect blue in sapphires.
The mines in Kashmir produced these sapphires for only a short period, making them exceedingly rare and valuable today. Although cornflower blue sapphires can also be found in Sri Lanka (Ceylon) and Myanmar (Burma), the Kashmir variety remains the most prized due to its superior color and clarity.
What Makes Cornflower Blue Sapphire Unique?
Several factors contribute to the uniqueness of cornflower blue sapphires:
1. Color
The most defining characteristic of a cornflower blue sapphire is its color. The ideal cornflower blue sapphire exhibits a pure, intense blue that is neither too light nor too dark. The color should be uniform throughout the stone, without any zoning or patches of different shades.
2. Clarity
Clarity refers to the presence of inclusions or flaws within the gemstone. While most sapphires contain some inclusions, cornflower blue sapphires are valued for their exceptional clarity. The fewer the inclusions, the more valuable the sapphire, as long as they do not detract from the stone’s beauty.
3. Cut
The cut of a sapphire greatly affects its overall appearance. A well-cut cornflower blue sapphire will reflect light evenly across its surface, enhancing its brilliance and making the color appear more vivid. Common cuts for cornflower blue sapphires include oval, cushion, and round.
4. Carat Weight
Like all gemstones, the value of a cornflower blue sapphire increases with its carat weight. However, due to the rarity of high-quality stones, even smaller cornflower blue sapphires can command significant prices if they possess the ideal color, clarity, and cut.
Factors Affecting the Value of Cornflower Blue Sapphire
When evaluating the value of a cornflower blue sapphire, gemologists and appraisers consider several key factors:
1. Origin
As mentioned earlier, the origin of a sapphire can significantly impact its value. Kashmir sapphires are considered the pinnacle of cornflower blue sapphires due to their unparalleled color and rarity. Burmese and Sri Lankan sapphires are also highly regarded, though they may be slightly less valuable than their Kashmir counterparts.
2. Treatment
Many sapphires on the market undergo treatments to enhance their color and clarity. The most common treatments include heat treatment and diffusion. While treated sapphires can still be beautiful, untreated cornflower blue sapphires are far more valuable due to their natural and unaltered state.
3. Certification
Certification from a reputable gemological laboratory is crucial when purchasing a cornflower blue sapphire. Certificates from organizations like the Gemological Institute of America (GIA) or the American Gemological Laboratories (AGL) provide assurance of the gemstone’s authenticity, origin, and any treatments it may have undergone.
4. Market Demand
The rarity and desirability of cornflower blue sapphires mean that they are always in high demand. However, fluctuations in the global market can influence their value. For instance, the discovery of new sapphire deposits or changes in fashion trends can impact prices.
Cornflower Blue Sapphire in Jewelry
Cornflower blue sapphires have long been a favorite among royalty and celebrities, often featured in some of the world’s most famous pieces of jewelry. One notable example is the sapphire engagement ring worn by Princess Diana and later passed down to Kate Middleton, the Duchess of Cambridge. This iconic ring, featuring a stunning oval cornflower blue sapphire surrounded by diamonds, has inspired countless replicas and continues to be a symbol of timeless elegance.
When set in jewelry, cornflower blue sapphires are often paired with diamonds or other complementary gemstones to enhance their beauty. They are commonly used in rings, necklaces, earrings, and bracelets, with designs ranging from classic to contemporary. The durability of sapphires, second only to diamonds, makes them an excellent choice for everyday wear.

Caring for Your Cornflower Blue Sapphire
Proper care is essential to maintain the beauty and longevity of your cornflower blue sapphire. Here are some tips to keep your gemstone looking its best:
1. Cleaning
Cornflower blue sapphires can be cleaned using warm soapy water and a soft brush. Be sure to rinse the gemstone thoroughly and dry it with a soft cloth. Avoid using harsh chemicals or ultrasonic cleaners, as these can damage the stone or its setting.
2. Storage
Store your sapphire jewelry separately from other pieces to prevent scratching. Ideally, each piece should be placed in a soft pouch or lined jewelry box. Avoid exposing your sapphire to extreme temperatures or sudden changes in temperature, as this can cause the stone to crack.
