 Gradient Sapphire is a gemstone with a color transition effect, usually showing gradient features from dark to light or different tones on a single gemstone. 1. Color transition: The biggest feature of gradient sapphires is that the color gradually changes from one end to the other, such as from dark blue to light blue, green-blue, or even multi-color gradients (such as blue to green or blue to pink).
