Zircon price: what natural zircon is worth per carat
Natural zircon is a brilliant, high-dispersion gem often confused with the synthetic imitation cubic zirconia. Fine blue zircon is the most sought-after and valuable colour.
What drives zircon price
Zircon is a natural gemstone with exceptional brilliance and fire, not to be confused with cubic zirconia, an unrelated synthetic diamond imitation. Colour is the main value driver, and vivid blue zircon is the most popular and valuable.
Colour
- Blue — an intense sky-to-teal blue (heat-treated from brown rough) commands the strongest prices.
- Golden, honey, red and green — attractive earth tones, generally more affordable; some greens are rarer.
- White/colourless — used as a natural diamond substitute for its fire.
Size, clarity & brilliance
Zircon is usually eye-clean with outstanding brilliance and high dispersion. Larger clean blue stones are less common, so per-carat prices rise with size.
Treatment
Most blue and colourless zircon is heat-treated, which is standard and accepted. Untreated earth-tone stones also occur.
