What is Green Sapphire? Green Sapphire, also called Green Safir or Green Pukhraj (हरा पख ु राज) in Hindi, is a variety of sapphire that belongs to the mineral family known as corundum. While sapphires are most commonly recognized in blue and yellow shades, they are also found in green tones. The green color in this gemstone is caused by the presence of iron within the crystal structure. Its shade can vary from pale green to deeper, earthy green, and sometimes it may display slight yellowish or bluish undertones. Green sapphires are sourced from countries such as Sri Lanka, Madagascar, Thailand, Australia, Tanzania, and Nigeria. Stones from Sri Lanka are typically lighter in color and offer better transparency. Known for its strength, green sapphire ranks 9 on the Mohs hardness scale, making it highly durable and suitable for everyday jewellery like rings and pendants. In astrology, it is associated with the planet Mercury and is believed to enhance communication skills and mental clarity.

Green Sapphire vs Emerald: What Are the Key Differences? Although both gemstones are green, their differences go beyond appearance.
1. Formation and Origin Emerald forms deep within the Earth under unique geological conditions. It develops when beryllium, aluminum, and small traces of chromium or vanadium combine under heat and pressure. This process often creates internal inclusions, which are natural and expected in emeralds. Colombia and Zambia are among the most renowned sources. Green sapphire, on the other hand, forms in igneous and metamorphic rocks under high temperatures. As part of the corundum family, its green shade results from iron during formation. Its crystal structure is generally stronger and more stable.
2. Colour and Appearance

Emerald is admired for its vivid and intense green color. Most emeralds contain visible inclusions, commonly referred to as “jardin,” which are considered part of their natural identity. Green sapphire typically displays a softer green tone, ranging from light to deep shades. It may have slight yellow or bluish hints. Compared to emerald, green sapphire usually has fewer inclusions and appears clearer.
3. Strength and Durability Emerald has good hardness but can be fragile due to natural inclusions. It requires careful handling, especially in daily-wear rings. Green sapphire is significantly tougher, ranking 9 on the Mohs scale. Its strong structure makes it more resistant to scratches and damage, making it ideal for everyday jewellery.
4. Clarity and Treatment Most emeralds undergo oil treatment to improve their clarity and overall look. This is a standard practice in the gemstone industry. Emeralds with minimal inclusions are rare and command higher prices. Green sapphire is commonly heat-treated to enhance its color. Naturally clear stones are more common in sapphire than in emerald.
5. Price and Market Value
