| 【With loose stone identification report】 A rare gemstone with a very vivid color change! Cuprite 2.87 CT
Cuprite, also known as red copper ore, is a copper oxide mineral, and its name is derived from copper. What is unique about this gemstone is that it exhibits a slightly different color change from typical color-changing stones. Color-changing stones such as alexandrite often change the color of their crystals. However, when cuprite is exposed to incandescent light, it changes color as if red brilliance spills out from deep within the crystal. The crimson glow overflowing from its luster, which resembles a black diamond before the change, is very impressive and beautiful. Gem-quality specimens are rare and said to be difficult to find. What you are seeing is a powerful crystal weighing over 2.8 CT. As this is also a gemstone not commonly circulated, we recommend collectors secure it early. |
