1, zircon hardness is not high, so under the magnifying glass, you can see that the ridge line is not straight and worn; Moss stone is a birefringent gem, so there is a double image under the magnifying glass; The diamond is straight, with sharp facets and diamond luster.

2. Compared with a round diamond with a diameter of 6.5 mm, the weight of a diamond with a diameter of 6.5 mm is about 1 carat; Moss stone with a diameter of 6.5 mm weighs about 0.9 carats; Zircon with a diameter of 6.5 mm is about 1.9 carat.

3. Zircon can not refract light, but can only reflect light, so there is no fire color; The refractive index of mosan stone is 2.65, which is larger than that of diamond 2.4 17.

It is very good to compare the fire color with the magic star diamond which only sells the best quality Mosan diamonds. Belgian magic star diamonds can really reach D color, and the clarity can reach FL/IF. In terms of fire color, the fire color of diamond is not as bright as that of Mosan stone, and in terms of quality, Belgian magic star diamond is homogeneous with diamond.
