Zircon is known as one of the oldest minerals on earth, and is a gemstone with a wide variety of colors. Its particularly strong birefringence creates a unique visual effect called "doubling," which makes its sparkle stand out.
This is a color-change zircon, also known as a "reverse color change" zircon, whose color impression changes depending on a specific light source. Under indoor fluorescent lights, it appears an elegant grayish blue, but changes to blue under sunlight or LED lights. Furthermore, if you shine a penlight (incandescent light) on it, you can feel a soft green, making it an attractive stone that you can enjoy different expressions depending on the type of light.
