What you want to ask is the yellow plus green gentian agate necklace bought for 50 yuan. Is it true?/You don't say. Fake. Yellow-green gentian agate is a common mineral, which can stimulate gallbladder and liver function. The bracelet made of this stone, if it is really yellow-green gentian stone, has certain collection and investment value. So the price is expensive. The identification of agate can be carried out from the following three aspects.

1, transparency, agate can be identified by transparency, and natural agate is generally transparent, which will give people a turbid feeling when observed in the sun. Most synthetic agates are very transparent and can be as transparent as glass balls.

2, pattern, the pattern of natural agate is very different from that of synthetic agate, the striped pattern of natural agate will be more obvious, and the color will be bright and bright. The synthetic agate stripe pattern will be relatively simple. Although its color is gorgeous, it will give people a gaudy feeling.

3, texture, the texture of true and false agate will also be different, so you can identify the true and false by looking at the texture. Natural agate is relatively hard, not easy to be scratched, and has fewer defects than fake agate, while fake agate is mostly imitation stone with relatively soft texture.
