Rarity and Value
Kashmere sapphires are found in a remote region of Kashmir, India, and their production is limited due to the depletion of the mines. The scarcity of these sapphires contributes to their high value, making them one of the most expensive gemstones in the world.
Historical Examples
Throughout history, cashmere sapphires have been coveted by royalty and collectors. Notable examples include:
- The Star of India, a 563-carat star sapphire currently housed in the American Museum of Natural History.
- The Kashmir Sapphire, a 42.29-carat oval-cut sapphire owned by Cartier.
Unique Characteristics
Kashmere sapphires possess several unique characteristics that distinguish them from other sapphires:
- Velvety Blue Hue:Their deep blue color is reminiscent of the velvety texture of cashmere wool.
- Exceptional Clarity:Kashmere sapphires are known for their exceptional clarity, often exhibiting a flawless appearance.
- High Saturation:The blue color of cashmere sapphires is highly saturated, resulting in a vibrant and intense hue.
- Fluorescence:Many cashmere sapphires exhibit a strong blue fluorescence under ultraviolet light.
Geology and Formation
Kashmere sapphires are formed in unique geological conditions characterized by the presence of beryllium-rich pegmatites. These pegmatites are igneous rocks that form when magma cools and crystallizes, resulting in the formation of large crystals. The presence of beryllium in the pegmatites contributes to the distinctive color and appearance of Kashmere sapphires.
Impurities and inclusions play a significant role in shaping the color and appearance of Kashmere sapphires. Iron impurities give the sapphires their characteristic blue color, while titanium impurities can produce a greenish hue. The presence of rutile inclusions, known as “silk,” can create a silky sheen or chatoyancy in the stones.
Mining and Extraction Methods
Kashmere sapphires are primarily mined in Sri Lanka, where they are found in alluvial deposits and pegmatites. Alluvial mining involves extracting sapphires from riverbeds and gravel deposits, while pegmatite mining involves extracting sapphires directly from the pegmatite rocks. Both methods require careful and skilled techniques to minimize damage to the delicate sapphires.
Color and Clarity
Cashmere sapphires exhibit a captivating range of colors, spanning from delicate pastel hues to deep, saturated tones. The most sought-after shades include soft lavender, pale pink, and a distinctive baby blue. These colors are often described as ethereal and dreamy, resembling the soft, luxurious fabric from which the gemstone derives its name.
The clarity of cashmere sapphires plays a crucial role in determining their brilliance and overall value. High-clarity stones are characterized by minimal inclusions, allowing light to pass through unimpeded, resulting in a radiant sparkle. Factors such as the presence of tiny crystals, fractures, or cloudiness can affect the clarity of the gemstone.
Color Grades
- Faint:Extremely pale color, barely discernible from colorless.
- Very Light:Subtle color, visible under close examination.
- Light:Noticeable color, easily seen in natural light.

Cut and Design
The cut and design of a cashmere sapphire play a crucial role in maximizing its beauty and brilliance. Ideal cuts enhance the gemstone’s inherent qualities, allowing its color, clarity, and fire to shine through.
Symmetry and proportions are key considerations in the cutting process. Well-proportioned stones with balanced facets create a harmonious appearance and allow light to enter and reflect within the gemstone, resulting in optimal brilliance and scintillation.
Polish and Finish
A high-quality polish is essential for bringing out the cashmere sapphire’s natural luster and clarity. A smooth, mirror-like finish allows light to interact with the gemstone’s surface, enhancing its fire and brilliance. Proper polishing techniques also minimize scratches and imperfections, preserving the gemstone’s beauty for years to come.

Imitations and Treatments
Cashmere sapphires are highly sought after for their unique color and luster. However, like many other gemstones, they can be imitated or treated to enhance their appearance. Understanding these methods is crucial for informed decision-making when purchasing cashmere sapphires.
Imitations
Synthetic sapphires, also known as lab-created sapphires, are grown in a controlled environment and exhibit similar chemical and optical properties to natural cashmere sapphires. They are typically more affordable than natural stones and may be difficult to distinguish without specialized equipment.
Glass and cubic zirconia (CZ) are other common imitations of cashmere sapphires. Glass is typically less durable and has a lower refractive index, resulting in a less vibrant appearance. CZ, on the other hand, is harder but may exhibit a more artificial blue hue.
Treatments, Cashmere sapphire
Cashmere sapphires may undergo various treatments to improve their clarity, color, and overall appearance. These include:
- Heat treatment:This process involves heating the sapphire to a high temperature to remove impurities and enhance its color. Heat treatment is a common and accepted practice in the gemstone industry.
- Diffusion treatment:This technique involves diffusing a colored substance, such as beryllium, into the sapphire to alter its color. Diffusion treatment is less common and may affect the stone’s durability.
- Clarity enhancement:Fractures and inclusions in the sapphire can be filled with a transparent material to improve its clarity. This treatment is often used on lower-quality stones.
Identifying Genuine Cashmere Sapphires
Distinguishing genuine cashmere sapphires from imitations and treated stones requires careful examination. Consider the following tips:
- Color:Natural cashmere sapphires typically exhibit a soft, velvety blue color with a slight purplish hue. Imitations may appear too vibrant or have an artificial blue hue.
- Clarity:Natural sapphires often contain inclusions or imperfections. Flawless or excessively clear stones may be imitations or treated.
- Luster:Genuine cashmere sapphires possess a distinctive luster that is difficult to replicate in imitations. Imitations may have a glassy or dull appearance.
- Certification:Reputable jewelers provide certificates from recognized gemological laboratories, such as the Gemological Institute of America (GIA), to guarantee the authenticity and quality of the stone.
