Discover the Beauty and Secrets of Sapphire

Sapphire, one of the most treasured gemstones in the world, belongs to the corundum family and is celebrated for its exceptional durability—second only to diamond. While blue is the most famous color, sapphires can also appear in pink, yellow, green, purple, and many other shades, with red corundum being classified as ruby. Known as the birthstone of September, sapphire has long symbolized wisdom, truth, and loyalty. Each sapphire carries unique natural inclusions, often called “fingerprints of nature,” which not only enhance its individuality but also provide gemologists with vital clues about the stone’s authenticity and origin. At Unity Gem Lab, we study these inclusions with advanced techniques to ensure precise identification and trustworthy certification for every gemstone.
