Water bile agate carving, authentic.

Carefully carved, the color is dark and the luster is delicate.

The value of water bile agate depends more on the shape of the water bladder, which requires large water, sufficient water and clear appearance.

If you can hear the sound of water, it is the top grade.

It's hard to evaluate the cost performance because this water diversion bag can't be observed in the photo.

Natural products, please rest assured, you can ask whether the size of this water bag described in is clearly visible to the naked eye.

If the courage is too small, then the value is not high and the starting price is expensive.

If the water bag is bigger than the egg, even if the price is not very cost-effective, then the future appreciation space and collection significance are great and have great potential.

For details, please refer to my first article in Baidu Space and examples of comparing photo albums.

If you have any questions, just ask.

I hope the answer can help you.
