Yellow sapphires, commonly known as Pukhraj in India, have long been revered throughout history for their mystical properties. Legends speak of their ability to protect wearers from harm and bring them prosperity. In ancient Greece, they were believed to possess healing powers, valued for their ability to restore health and vitality. Traditional medicine also utilized yellow sapphires in various remedies.
Today, yellow sapphires are increasingly popular in modern jewelry designs. Jenny McCarthy's engagement ring, featuring a stunning 10-carat square-cut yellow sapphire, is a notable example of their beauty and significance. Beyond their aesthetic appeal, these gems are symbols of wisdom and success, often chosen as meaningful gifts to mark new beginnings.
1. Formation and Occurrence of Yellow Sapphires
Yellow sapphires, known for their vibrant hues and durability, hold a special place among gem enthusiasts. Belonging to the corundum mineral family, they boast shades ranging from pale lemon to deep fluorescent yellow.
Like other sapphires, yellow ones form deep within the Earth's crust through geological processes. Created in metamorphic and igneous environments, they endure high heat and pressure conducive to corundum mineral formation. Typically found in alluvial deposits formed by erosion, they accumulate in areas like riverbeds.
During formation, impurities like iron become trapped within, imparting the yellow hue. Variations exist, with some stones displaying mixed hues like yellow-blue ("Pitambari") or yellow-green ("Parti"). Notably, Sri Lanka, Australia, and Madagascar are key sources of high-quality yellow sapphires, prized for their color saturation and clarity.
2. Global Origins of Yellow Sapphires
Yellow sapphires hail from various regions worldwide, with notable origins including:
- Sri Lanka (Ceylon): Renowned for bright, pure-colored sapphires, often lacking green undertones.
- Madagascar: Known for vibrant hues and transparency, particularly in the Ilakaka region.
- Australia: Queensland and New South Wales yield high-quality specimens with vibrant yellow to intense gold hues.
- Thailand: A hub for cutting, polishing, and trading, known for deep yellow and golden sapphires.
Other regions like Myanmar, Tanzania, Russia, and Brazil also contribute to the market with their unique geological traits, offering a diverse range of colors and qualities.
3. Variations in Yellow Sapphires
Yellow sapphires exhibit a broad spectrum of colors, from pale yellow to intense canary and orangish-yellow, influenced by trace elements and geological conditions. Desirable specimens boast bright, uniformly saturated yellow hues. Secondary hues like golden, orange, or greenish undertones add to their allure, making each stone unique.
4. Typical Inclusions in Yellow Sapphires
Inclusions are common in yellow sapphires, offering insights into their formation and history. One prevalent type is "silk," fine needle-like structures resembling delicate strands, affecting light interaction.
Another common inclusion is feathers, natural fractures that heal over time, typically small and minimally affecting quality.
Some yellow sapphires may contain beryllium traces, enhancing color through heating. However, those treated with lead glass, especially from Thailand, are considered of lower quality due to stability concerns.
While flawless stones hold allure, inclusions add uniqueness and charm to yellow sapphires, enriching their stories.
5. Common Treatments and Enhancements of Yellow Sapphires
Yellow sapphires often undergo treatments to improve color and clarity, with thermal enhancement being the most prevalent. In this process, the gemstone is heated in a specialized furnace at temperatures ranging from 1200°C to 1800°C. Careful monitoring ensures desired color enhancement, making even pale-yellow sapphires more vibrant.
Thermal enhancement is widely accepted in the industry for its effectiveness in enhancing visual qualities. However, caution is advised regarding beryllium infusion during heat treatment, as it can impact the stone's structural integrity and value.

6. Assessing the Quality of Yellow Sapphires
Quality evaluation of yellow sapphires involves several key factors:
Color: The hue, saturation, and intensity of yellow are crucial. The finest specimens display a vibrant, pure yellow hue without undertones of brown or green.
Clarity: Minimal inclusions, such as feathers or silk, contribute to high transparency. Yellow sapphires generally have fewer inclusions compared to other corundum varieties.
Cut: Well-executed cuts maximize brilliance, sparkle, and color display by optimizing symmetry and proportions.
Carat Weight: While weight matters, it's not the sole determinant of quality. Generally, weights between 3 and 6 carats are standard, with larger stones commanding premiums.
Origin: Stones from renowned sources like Sri Lanka often exhibit exceptional quality and command higher prices.
Consulting a reputable jeweler or gemologist is advisable for accurate assessment.
7. Pricing of Yellow Sapphires
Yellow sapphires offer a wide price range, influenced by factors such as color saturation, clarity, and origin. Intensely colored, transparent stones fetch higher prices. Origin also impacts cost, with Thai sapphires typically less expensive due to beryllium treatments.
Prices range from $100 to $300 per carat for Thai stones, while Sri Lankan gems may start at $250 to $300 per carat and can reach tens of thousands for exceptional specimens. Burmese yellow sapphires are generally cheaper, ranging from $100 to $700 per carat.

What is the mantra before wearing yellow sapphire?
Vedic astrology suggests that the gemstone should be purified before you wear them. To purify Yellow Sapphire (Pukhraj), dip the gemstone thrice in Ganga-jal or raw cow-milk. While doing so chant, "Om Streem Brahm Brihaspataye Namah." Repeat the mantra 108 times and wear it while chanting it the last time.
How to activate Pukhraj ring?
Place it into a clean bowl. Now, energise the gemstone by reciting the holy Guru stone mantra for 108 times. After reciting the holy Pukhraj Ratna mantra take out the ring or pendant from the bowl and clean the gemstone with distilled water before wearing it.
How to know if Pukhraj suits you?
Astro Consultation: The best way to check if a Pukhraj Ratna suits you is to consult an astrologer. They can recommend you your lucky stone after examining your birth chart. If Peetamani is beneficial for you, they can also suggest the right gem carat, metal, and finger to wear.
