The cornflower blue sapphire is one of the most coveted and rare variants of sapphires in the world of fine jewelry. It is known for its vibrant and intense blue hue, which resembles the rich and delicate color of the cornflower bloom. These sapphires have become highly sought after due to their rarity, exceptional beauty, and the unique visual appeal they offer when set in various pieces of jewelry. In the world of gemstones, they are revered not only for their breathtaking appearance but also for their association with luxury and elegance.
Sapphires, in general, are part of the corundum family, a mineral known for its hardness and durability. While most sapphires are available in a range of colors, the cornflower blue sapphire has a distinctive shade that sets it apart from other gemstones. These sapphires have earned their place in the jewelry industry for their exceptional color and the rarity of the stones that possess this unique shade of blue.
History and Origin of Cornflower Blue Sapphire
The history of cornflower blue sapphires is closely linked to the broader history of sapphires, which have been used in jewelry for centuries. Sapphires have long been associated with royalty, nobility, and the rich, making them highly prized stones. However, the distinct cornflower blue sapphire gained particular attention in the 20th century, especially when famous jewelry houses began incorporating them into their high-end designs.
Cornflower blue sapphires are most commonly found in Sri Lanka, which has been a historical source of some of the finest sapphires. The island’s geological conditions contribute to the formation of sapphires with this particular vibrant blue color. In addition to Sri Lanka, cornflower blue sapphires have also been discovered in other parts of the world, including Myanmar, Madagascar, and Thailand, though Sri Lanka remains the most famous source for this specific gemstone.
Characteristics of Cornflower Blue Sapphire
Color
The defining characteristic of cornflower blue sapphires is their stunning, vivid blue color. Unlike other sapphires, which can range from pale blue to deep navy, cornflower blue sapphires possess a medium to slightly light blue hue, with a subtle violet undertone. This specific color is often compared to the shade of a cornflower blossom, which is where it gets its name.
The color intensity of a cornflower blue sapphire is measured using the GIA (Gemological Institute of America) color scale, which assesses both hue (the basic color), tone (lightness or darkness), and saturation (vividness or strength of color). A high-quality cornflower blue sapphire will have a rich, intense hue without being overly dark or light.
Clarity and Transparency
As with all gemstones, the clarity of a cornflower blue sapphire is an important factor in determining its value. While sapphires are known for their durability and resistance to damage, they can sometimes contain internal inclusions. These inclusions, or “blemishes,” can affect the transparency of the stone, and the fewer the inclusions, the higher the value of the sapphire.
However, it’s important to note that some inclusions, called “silk,” are considered acceptable in sapphires. These are tiny needle-like inclusions that are often visible under magnification. In fact, these inclusions can contribute to the stone’s unique character, though excessive inclusions that reduce transparency can lower the value of the gemstone.
Size and Shape
Cornflower blue sapphires are found in a variety of sizes and shapes, but the largest and most flawless stones tend to be the most expensive. The shape of a sapphire plays a significant role in how its color and brilliance are perceived. Popular cuts for cornflower blue sapphires include oval, cushion, round, and emerald cuts. Each cut enhances the gemstone’s natural characteristics and reflects light in different ways, showcasing the sapphire’s color to its fullest potential.
How to Identify a Cornflower Blue Sapphire
Identifying a cornflower blue sapphire involves considering a few key factors. First, the color should be a medium blue with a subtle hint of violet. While some sapphires can appear to be blue, only those with the specific cornflower hue are considered genuine cornflower blue sapphires.
Next, examining the gemstone for any inclusions is crucial. A quality cornflower blue sapphire should be relatively free of visible inclusions, though minor ones may be acceptable. A magnifying loupe is typically used by gemologists to assess the clarity and ensure that the stone is natural and not treated in any way.
The best way to identify a cornflower blue sapphire is to consult a certified gemologist or jeweler who can use advanced tools to assess the stone’s color, clarity, and overall quality. Many jewelers will also use certificates from gemological institutions like the GIA to confirm the authenticity and quality of the stone.
The Value of Cornflower Blue Sapphire
Cornflower blue sapphires are considered rare and valuable due to their distinct color and limited availability. In the world of gemstones, color is one of the most important factors in determining value, and the cornflower blue hue is highly prized for its beauty and rarity.
The value of a cornflower blue sapphire is determined by several factors:
Color: The deeper and more vibrant the color, the higher the value. The cornflower blue sapphire’s color intensity plays a significant role in pricing.
Size: Larger cornflower blue sapphires are extremely rare, and their value increases exponentially with size. A large, high-quality sapphire can command a much higher price than a smaller one.
Clarity: As mentioned, sapphires with fewer inclusions are valued more highly. The clearer the sapphire, the higher its market value.
Origin: Sapphires from Sri Lanka are often considered the best, especially for cornflower blue sapphires, and can therefore command higher prices. Other origins, while still valuable, might not reach the same price points.
Treatment: Most sapphires undergo heat treatment to enhance their color and clarity, but untreated sapphires are considered more valuable. Natural, untreated cornflower blue sapphires are extremely rare and highly sought after.
Overall, cornflower blue sapphires tend to be more expensive than other sapphires, thanks to their rarity and the high demand for their color and clarity.
