Sapphire - 1.42 ct - Instituto Gemólogico Español (IGE) - Leftovers Reheated Without Waste

Sapphire is a precious gemstone variety of the mineral corundum, known for its range of rich colors, with blue being the most famous. This 1.42 carat sapphire has been evaluated by the Instituto Gemólogico Español (IGE). The description "Leftovers Reheated Without Waste" suggests that the gem may have undergone heat treatment to enhance its color or clarity, a common and widely accepted practice in the gemstone industry. Heat treatment can intensify sapphire hues from pale or uneven tones to deep, vibrant blues and other colors. Sapphires are highly prized not only for their color but for their hardness, second only to diamonds, making them suitable for all types of jewelry. Their formation occurs in metamorphic and igneous rocks, and they can vary in color from blue, pink, yellow, and even colorless, with treated sapphires being a common portion of the market.
