There are several main steps to identify agate:
1.Observe the color: The color of agate is varied, there are various colors such as red, yellow, green, blue, black, etc. The color part of natural agate feels more moist, and the naturalness of this change is difficult for other gemstones to imitate.
2.Check the shape: Most agate stones are irregularly shaped, and this is because it is affected by pressure and temperature during the formation of the earth's crust, resulting in a unique shape.
3.Touch: Agate stone is hard, cool and slippery to the touch, and ordinary man-made objects cannot imitate this touch.
4.Check the crystals: Essentially, agate is made up of dense microcrystalline silica. If you look in sunlight or under a magnifying glass, you can see tiny crystals on its surface.
5.Check the texture of the agate in a pondering way. Real agate has a good texture, while fake agate drills with nails, and powder will fall out.
6.Breakage Inspection: If the agate changes color or cracks in strong light, it is a sign that it is a fake agate.
Finally, under normal circumstances, the identification of agate still requires some professional knowledge, such as hardness testing, density testing, etc., which requires some professional identification equipment. If you're unsure, the best thing to do is to take it to a professional testing facility.
