Introduction


When it comes to luxury gemstones, sapphires are among the most popular choices. Renowned for their brilliant blue color and remarkable durability, sapphires have been prized for centuries. While natural sapphires are highly valued, heated sapphires are an excellent option for those looking to find beauty and value in a gemstone. In this blog, we’ll explore the specifics of a 0.91ct heated sapphire, discussing its size, shape, and the process behind heat treatment that enhances its color and clarity.

What is a Heated Sapphire? A heated sapphire is a gemstone that has undergone a heat treatment process to improve its color and clarity. Sapphires, in their natural form, may have inclusions or may lack the intense color desired in fine jewelry. Heating the stone at high temperatures (usually 800–1,200 degrees Celsius) helps to enhance its hue, remove some inclusions, and improve its overall appearance. This treatment is widely accepted and is often used to bring out the best in sapphires, making them more affordable without compromising their beauty.

The 0.91ct Sapphire: Size and Dimensions The sapphire in focus weighs 0.91 carats and boasts dimensions of 6.70 x 4.81 x 3.23mm. This size falls within the ideal range for versatile jewelry pieces like rings, earrings, or necklaces. The dimensions show that the stone is well-proportioned, making it suitable for a variety of settings. With a carat weight just under one, this sapphire offers an excellent balance of size and price, which is a great option for buyers who want a stunning gemstone without breaking the bank.

Why Heat Treatment Matters Heat treatment is a common and widely accepted practice in the gemstone industry. While natural sapphires are beautiful, they may have subtle flaws or colors that are less than ideal. By applying controlled heat, gemologists can remove inclusions, improve the depth of color, and enhance the transparency of the stone. This treatment allows a sapphire to look more vibrant, as seen in our 0.91ct sapphire.

While heated sapphires are not considered “untreated” gemstones, they are still highly valued for their beauty, and the treatment does not diminish their value as much as some other treatments (like fracture filling). In fact, heat treatment can improve the overall durability of a sapphire and make it easier to maintain over time.

About Sri Lankan Sapphire (Ceylon Sapphire)

Renowned for its exceptional beauty and vibrant hues, Sri Lankan Sapphire—often referred to as Ceylon Sapphire—is one of the most sought-after gemstones in the world. Mined from the historic gem-rich lands of Sri Lanka, these sapphires are celebrated for their superior clarity, brilliance, and wide spectrum of colors, ranging from the classic royal blue to pink, yellow, green, and even colorless varieties.

Ceylon Sapphires are treasured not only for their aesthetic appeal but also for their durability and rarity. With a hardness of 9 on the Mohs scale, they are second only to diamonds, making them an ideal choice for fine jewelry, engagement rings, and investment-grade collections.

What sets Sri Lankan sapphires apart is their natural brilliance and often untreated origin, which enhances their value in the international market. Many collectors and spiritual gemstone users believe that Ceylon Sapphires carry strong metaphysical properties, promoting wisdom, protection, and inner peace.

Each Sri Lankan sapphire listed here is carefully selected for its quality, cut, and authenticity—directly sourced and handled with the utmost care and professionalism.
