Yellow sapphire is a designer favorite, often adorned to jewelry that captures its cool yellow color. The bright and lively gemstone is available in various sizes and shapes and looks exquisite set in both white and yellow metals. With its high refractive index and a hardness of nine on the Mohs scale, yellow sapphire makes for an excellent gemstone for necklaces, bracelets, earrings, brooches, and rings. Yellow sapphire can be found in a wide range of colors, blue, white, pink-red, yellow, and transparent, but the most common color remains a brilliant yellow.
The yellow color of yellow sapphire is created when colorless sapphire is exposed to irradiation and heat. Paler yellows are formed using electrons, while the darker yellow hues known as Super yellow and Sri-Lanka yellow are formed from exposure to neutrons. The color process to create the various shades of yellow sapphire can take minutes or years, as the high energy process of coloring sapphire requires the stone to be stored before the energy can be safely released. The colorless sapphire used in the process is generally mined in Sri Lanka, Brazil, or Thailand. The gemstones are typically cut before colored.
