Zircon displays double reflection from different angles and has a lower hardness and refractive index than diamond. It comes in various colors due to radioactive material, shows abrasions under magnification, and has a dimmer luster than diamond. While diamond is more expensive, zircon is a cheaper alternative option for those looking to purchase a gemstone.

2. Zircon offers double reflection, whereas, diamond
displays only one reflection from all angles. But in
case of zircon, it displays different reflection when
you see it from different angles.

3. Zircon stone has lower refractive index compared to
diamond stone. Its refractive index lies between
1.78-199 which is reasonably low as compared to
diamond stone refractive index.

4. The durability or hardness of zircon stone is 7 on the
Mohs scale which is comparative quite low from a
diamond that has a durability of 10 on Mohs scale.

5. With the presence of traces of radioactive material,
zircon stone offers a wide range of colors ranging
from white, blue, green, black, etc. On the other
hand, diamond offers only a single color.

6. Observing Zircon stone under the magnifier shows
some abrasions and inclusions on its facets. On the
other hand, diamond is crystal clean on the surface
when it is seen under the magnifier.

7. The luster or shine of Zircon stone fades in front of
the diamond stone. Comparing the shine of two
stones, it is quite evident that diamond easily
overpowers Zircon stone.

8. So, these are difference which helps one to
distinguish between the diamond and Zircon Stone.
Diamond is an expensive stone, hence, those who
are looking for cheaper option can opt for zircon
stone.
