How to distinguish between zircon and diamonds?

The Colorless zircon are very similar with diamonds and are often used as a substitute for diamonds. So what is the difference between zircon and diamonds? How to distinguish between zircon and diamonds?  Let’s take a look!

What is the difference between zircon and diamonds?

1, the essential difference

Diamond  is a natural mineral, is a carbon element composed of elemental crystals;

Zircon is also known as zircon, Japan called “hyacinth”, is a silicate mineral.

2, the difference between physical characteristics

Diamond has a lipophilic, a ballpoint pen can be in the diamond that can easily leave uninterrupted traces, of course, this trace can be easily wiped back, zircon does not have lipophilic, ball pen can not leave on its surface uninterrupted Clarity mark

3, the price difference

As we all know, the price of diamonds is very expensive. Although zircon is regarded as a substitute for diamonds, the price is related to a lot. Even the gem-class zircon, its price and the price of diamonds is also far from each other.

How to distinguish between zircon and diamonds

Observe the color of light.

Under the magnifying glass, the surface of the diamond often has triangular growth points and grooves, and the waist is showing a very fine scrub and sparkling reflected light. This feature of diamonds is unique. Although the hardness of zircon is high, good refraction, but in the rotation will reflect more of the IPL, and diamonds in the rotation only reflects the weak yellow, blue color contrast, there are significant differences.

Look at map method.

The diamond table is placed in a glassware to add water to the height of the diamond bottom position, with the converging light source vertically illuminating its bottom, when the container is taken away from the bearing. In the next bearing on the background can see a radiant image, and radiant away from the center of the light range, not like the zircon image, light and light field intertwined.

Water test.

The diamonds and zircons are cleaned, and then in their respective table drops of water droplets. If the water droplets can remain on the surface of the sample for a long time, then the sample is diamonds; if the water droplets quickly spread, then the description is zircon.

Hardness.

Under normal circumstances, the hardness of zircon compared to diamonds is not so high. Under the magnifying glass to observe the diamond section of the bright as new, and the zircon section of the general will appear potholes of small holes.
