Sapphires are formed deep within the Earth’s crust under intense heat and pressure, crystallizing from the mineral corundum (aluminium oxide). Trace elements like iron, titanium, and chromium give each sapphire its unique hue—from deep royal blue to vivid pink and yellow. Known for their exceptional hardness of 9 on the Mohs scale, sapphires are second only to diamonds, making them ideal for daily wear. Their high refractive index and brilliant luster enhance their captivating sparkle. These natural properties make sapphires a symbol of enduring strength and timeless beauty in fine jewellery.
Sapphires are graded based on their color, clarity, cut, and carat weight, which together define their brilliance and value. The most desirable stones feature vivid color tones, excellent transparency, and precise cutting for maximum sparkle. Expert gemologists use advanced testing to confirm authenticity and treatments, ensuring buyers receive genuine quality. Always look for certified GIA or IGI sapphire reports to guarantee the stone’s natural origin and true worth.
