When it comes to precious gemstones, few can match the timeless beauty and allure of the blue sapphire. Among the various cuts available, the round cut blue sapphire stands out as a classic and versatile choice. In this article, we will delve into the world of round cut blue sapphires, exploring their characteristics, qualities, and the factors that make them highly sought after in the jewelry industry.
The Origins of Sapphire
Sapphires belong to the corundum family, which also includes rubies. They are primarily composed of aluminum oxide. The blue color of sapphires is due to the presence of trace amounts of iron and titanium. These gemstones are found in various regions around the world, with notable sources including Sri Lanka, Myanmar, Madagascar, and Australia.
Sri Lanka is renowned for producing some of the finest sapphires. The sapphires from this region are often characterized by their rich, velvety blue color and exceptional clarity. Myanmar, particularly the Mogok region, is also famous for its high-quality sapphires. These stones typically have a deep blue hue and a strong saturation of color. Madagascar has emerged as a significant producer of sapphires in recent years, offering a wide range of colors and qualities. Australian sapphires, on the other hand, are known for their dark blue color and durability.
The Round Cut: A Popular Choice
The round cut is one of the most popular gemstone cuts, and for good reason. It is a versatile cut that enhances the beauty of the gemstone while maximizing its brilliance. The round cut has a symmetrical shape with 58 facets, which allows light to enter the stone and reflect back in a dazzling display of sparkle.
One of the key advantages of the round cut is its ability to highlight the color of the sapphire. The symmetrical facets ensure that the blue color is evenly distributed across the stone, creating a uniform and vibrant appearance. This is particularly important for blue sapphires, as the color is one of the primary factors that determine their value.
The Importance of Color
Color is one of the most critical factors when it comes to evaluating the quality of a blue sapphire. The ideal blue sapphire should have a rich, deep blue color with strong saturation. The color should be even throughout the stone, without any zoning or areas of lighter or darker color.
The shade of blue can vary from a light sky blue to a deep navy blue. While personal preference plays a role in choosing the shade, the most valuable sapphires typically have a medium to dark blue color. This shade is often referred to as “cornflower blue,” which is a vibrant and intense blue that is highly sought after in the jewelry industry.
It is important to note that the color of a sapphire can appear different under various lighting conditions. Natural daylight is the best light source to view the true color of a sapphire. However, sapphires should also look good under indoor lighting, such as incandescent or LED lights. A high-quality sapphire will maintain its beautiful blue color regardless of the lighting conditions.
Clarity: A Key Factor
Clarity refers to the presence or absence of inclusions within the gemstone. Inclusions are natural imperfections that can affect the appearance and value of the sapphire. While some inclusions are common in sapphires, the overall clarity of the stone is still an important factor to consider.
In general, sapphires with fewer inclusions are more valuable. However, it is important to note that completely flawless sapphires are extremely rare. Most sapphires will have some inclusions, such as small crystals, feathers, or color zoning. The key is to find a balance between the presence of inclusions and the overall beauty of the stone.
When evaluating the clarity of a round cut blue sapphire, it is important to look at the size, number, and location of the inclusions. Inclusions that are large or located near the surface of the stone can be more visible and may affect the stone’s durability. On the other hand, small inclusions that are located deep within the stone may not be visible to the naked eye and may not significantly impact the stone’s appearance.
Carat Weight: Size Matters
The carat weight of a sapphire refers to its size and is an important factor in determining its value. Generally, larger sapphires are rarer and more valuable than smaller ones. However, it is important to note that size is not the only factor that determines the value of a sapphire. A large sapphire with poor color or clarity may not be as valuable as a smaller sapphire with excellent color and clarity.

However, it is important to note that size is not the only factor that determines the value of a sapphire. A large sapphire with poor color or clarity may not be as valuable as a smaller sapphire with excellent color and clarity.
When choosing a round cut blue sapphire, it is important to consider the size that will best suit your needs. For example, if you are looking for a sapphire to be used in a ring, you may want to consider a size that is proportional to the size of your finger. A sapphire that is too large may be impractical for everyday wear, while a sapphire that is too small may not have the desired impact.
It is also important to note that the price per carat of a sapphire increases significantly as the size increases. This is because larger sapphires are rarer and more difficult to find. Therefore, it is important to carefully consider your budget when choosing the carat weight of your sapphire.
Enhancements: Heat Treatment
Many sapphires undergo some form of enhancement to improve their appearance. The most common enhancement for sapphires is heat treatment. Heat treatment involves heating the sapphire to a high temperature in a controlled environment. This process can improve the color, clarity, and overall appearance of the stone.
Heat treatment is a widely accepted practice in the jewelry industry and is considered a stable and permanent enhancement. In fact, many of the finest sapphires on the market have undergone heat treatment. However, it is important to disclose any enhancements that have been performed on the sapphire, as this can affect its value.
It is important to note that not all sapphires are suitable for heat treatment. Some sapphires may have inclusions or other characteristics that could be affected by the heat treatment process. Therefore, it is important to work with a reputable jeweler who can provide information about the enhancements that have been performed on the sapphire.
Setting Options for Round Cut Blue Sapphire

Prong Setting
The prong setting is one of the most popular settings for round cut sapphires. It involves using metal prongs to hold the sapphire in place. This setting allows maximum light to enter the stone, enhancing its brilliance and sparkle. The prong setting is also a secure option, ensuring that the sapphire is held firmly in place.
Bezel Setting
The bezel setting involves surrounding the sapphire with a metal rim. This setting provides a sleek and modern look and offers excellent protection for the sapphire. The bezel setting is a good choice for those who want a more subtle and understated look. It is also a secure setting, making it suitable for everyday wear.
Halo Setting
The halo setting involves surrounding the round cut sapphire with a halo of smaller diamonds or other gemstones. This setting adds extra sparkle and dimension to the jewelry piece. The halo setting is a popular choice for engagement rings and other special occasion jewelry. It creates a luxurious and elegant look that is sure to turn heads.

The pave setting involves setting small diamonds or other gemstones closely together to create a paved effect. This setting can be used to enhance the round cut blue sapphire by adding extra sparkle and brilliance. The pave setting is a good choice for those who want a more intricate and detailed look.
