水草玛瑙手镯（收于2016年）水草玛瑙中的水草是水草化石吗？水草玛瑙中我们看到的“水草”有人以为它是水草化石，其实不是。它是各种颜色的二氧化硅胶体溶液所形成，由于形成的过程很缓慢，所以是一层一层自外而里凝结，因其夹杂氧化金属，每一层的颜色因所含微量元素的不同而不同，颜色可从极淡色以至暗色。

形成原因是上亿年前，由于某种自然现象，地壳的剧烈运动，地下的岩浆喷涌而出，迅速冷却后产生气泡，这些气泡经过漫长时间，被二氧化硅溶液凝结成胶状物质入侵而成，常为多晶集合体，通常呈条带状、同心环状、云雾状或树枝状分布，颜色不一，视其所含杂质种类及多寡而定，以白色、灰色、棕色和红棕色为最常见，黑色、蓝色及其他颜色亦有，蜡样光泽，半透明至透明。

由于每个地方所形成的条件和所含物质不同，就会出现不同质量、不同造型的“水草”。Are aquatic plants in aquatic plants agate fossil aquatic plants? Some people think that the "aquatic plants" we see in the aquatic plants agate are fossil aquatic plants, but they are not. It is formed by silica colloidal solutions of various colors. Due to the slow formation process, it condenses layer by layer from the outside to the inside. Due to its inclusion of oxidized metal, the color of each layer varies according to the trace elements contained. The color can range from extremely light to dark.

The reason for the formation is that hundreds of millions of years ago, due to some natural phenomenon, the intense movement of the earth's crust, underground magma gushed out and produced bubbles after rapid cooling. After a long period of time, these bubbles were formed by the invasion of colloidal substances condensed by silica solution. They are usually polycrystalline aggregates, usually distributed in strips, concentric rings, clouds or dendrites, with different colors depending on the type and amount of impurities contained. White, gray, brown and reddish brown are the most common colors, and black, blue and other colors are also present, with wax-like luster and translucency to transparency.

Due to the different conditions and substances formed in each place, there will be "aquatic plants" of different quality and different shapes.
