Kornerupine Blind Pour 10.63ctw, 5 stones from Tanzania
Kornerupine is a rare borosilicate mineral, and gem-grade specimens are even rarer. Its discovery dates back to 1884 in Greenland, and it's named after Danish geologist Andreas Nikolaus Kornerup.
Kornerupine comes in a range of colors, including dark olive green, light blue-violet, orange, and nearly colorless. However, the most desirable colors are the vibrant greens and blues that we have in stock. What makes Kornerupine truly unique is its high pleochroism, which means that a single gemstone can display multiple color hues.
Not only is Kornerupine visually stunning, but it's also a practical choice for jewelry due to its relatively high hardness of 6.5-7.0 on the Mohs scale and decent toughness. So if you're looking for a rare and durable gemstone, Kornerupine might just be what you need.
