The price of a blue zircon can vary widely depending on several factors, including the gemstone's quality, size, color, clarity, cut, and origin, as well as market demand and prevailing economic conditions. To provide you with a general idea, I can provide a rough price range based on common blue zircon characteristics:

• For smaller blue zircons (under 1 carat), prices typically start around THB1,500 to THB 3,500 per carat (or about US$50 to $100) for commercial-grade stones with fair to good color and clarity. As the size increases and the quality improves, prices can range from THB 5,000 to THB 17,000 per carat (or US$150 to $500) for stones with better color saturation, clarity, and cutting precision.
• For blue zircons in the 1 to 5 carat range, prices can range from THB 10,000 and above per carat (or US$300 above) for stones with good to excellent color, clarity, and cutting. Exceptional blue zircons, particularly those with vivid blue color, excellent clarity, and precision cutting, can command prices above THB 70,000 per carat (or US$2,000).

Does Blue Zircon Fade?

Simple answer: NO.

However, it's worth noting that extreme heat and prolonged exposure to intense sunlight can potentially affect the color of blue zircon. Excessive heat can cause the gemstone to lose its blue hue temporarily, appearing colorless or pale. This phenomenon is known as "thermal shock." Fortunately, the color typically returns once the gemstone cools down.

Blue zircon is generally a stable and durable gemstone, and its color does not fade over time under normal wear and exposure to light.
