Zircon and diamond have different chemical compositions, different crystal shapes, different colors, different luster, different production sources, different hard points, different melting points, and so on.
1, the difference in chemical composition
Zircon: The main chemical composition is zirconium silicate.
2, the difference in crystal shape
3, the difference in color
The color of diamonds can generally be divided into two categories: colorless and light yellow (brown, gray) color series and color series.
The luster of a diamond is diamond luster.
The luster of zircon is diamond luster to glass luster.
6, the difference in hardness
Diamonds are the hardest of all natural minerals, with a hardness of 10.
Diamond melting point 3550-4000°C.
Zircon melting point 2340~2550°C.
The specific gravity of zircon is 4.69.
Two stones of the same volume, the heavy is zircon, the light is diamond.
Some low-form zircons contain radioactive elements that can harm health.
