Nature has an amazing way of playing with colors. From the fiery hues of a sunset to the colorful radiance of a rainbow. One of the most fascinating displays of natural color is gemstone dispersion.

When turned in the light, some gemstones display a fascinating play of colors: thousands of points of light in the colors of the rainbow flash and dance around the jewel with each turn. This optical phenomenon is called "dispersion." In gemology, it is known as "fire" and is considered a quality characteristic of gemstones.

大自然演繹色彩的方式令人驚嘆，從日落的火紅余暉到彩虹的絢麗光芒。其中最迷人的色彩展示當屬寶石的色散現象。

當寶石在光線下轉動時，有些寶石會呈現出迷人的色彩變幻：隨著角度變化，無數彩虹色光點在寶石周圍閃爍舞動。這種光學現象叫做“色散”。在寶石學領域中被稱為“火彩”，是寶石的一種品質特征。
