Look at the color first. Natural agate is bright and bright with stripes, and high-quality agate also has oily luster.

Second, look at transparency. Natural agate is not as transparent as synthetic agate, just like there are "clouds" in crystal.

Third, measure the temperature. Natural agate is warm in winter and cool in summer, while imitation agate will change its temperature with the change of temperature.

Fourth, look at the texture. Natural agate is hard, and imitations are easily imprinted by jade and the like.

Step 5 weigh. Natural agate ornaments are heavier than synthetic agate ornaments.
