In the face of the mixed diamond market, how to buy a good quality diamond ring is the wish of many people. Since the refractive index of zircon is close to 2.417, the dispersion is similar to that of diamonds. From the appearance, zircon will also shine, very similar to diamonds, so how to distinguish them? There are five simple ways to do this.

Observing color light

Under the magnifying glass, the surface of the diamond often has triangular growth points and grooves, and the waist has a fine sand-like shape with sparkling light. This feature of the diamond is unique. Although the hardness of the zircon is high and the refraction is good, it will reflect more color light when it is rotated, and the diamond will reflect only the weak yellow and blue color light when rotating, and there is a significant difference.

Observation section

In general, the hardness of zircon is not as high as that of diamonds. Observed under the magnifying glass, the cut surface of the diamond is as bright as new, and the cut surface of the zircon generally has a small hole in the pit.

Transmission line

Because the cutting of diamonds is usually standard, almost no light can be faceted through the pavilion. In view of the total internal reflection of the diamond, no straight lines are visible, and zircon twists the straight line. However, black lines are not seen in the case of artificial titanic acid and synthetic rutile, so this method is used with caution.

Water test

Clean the diamonds and zircons, then drop the water droplets on the respective countertops. If the water droplets can remain on the surface of the sample for a long time, the sample is a diamond; if the water droplets spread quickly, it is zircon.

Look at the map

Pour the diamond countertop into a glassware and add water to the height of the tip of the diamond to illuminate the light source vertically to illuminate the bottom tip of the container. A radiant image can be seen on the background of the underlying object, and the ray of light is far from the center of the light range, unlike the image of zircon, the light is intertwined with the light field.
