How To Distinguish Between Zircon And Diamonds

Transparency test: If you draw a line on the paper, put the "diamond" on the paper. If you can see the line through the "diamond", it is not a diamond, because the diamond will reflect 100% of the light, should Can't see anything.

Humidity test: To the ore, the gas spreads very quickly. The surface of the diamond is very smooth, it can't hold water and condensate.

Defect test: Carefully observe the ore with a magnifying glass. If you can observe some small flaws inside the ore, then this is a real diamond. Unless this is a very perfect diamond (almost impossible). Fake diamonds are always very pure and very clear.

UV test: If there is a relatively high-end equipment, it can be observed by ultraviolet light. If it can change color, it is a real diamond, because the real diamond is responsive to ultraviolet light.
