The rarest color of the aurora borealis is often considered to be purple or violet. While green is the most common hue due to the excitation of oxygen molecules at lower altitudes, purple shades occur at higher altitudes and are produced by nitrogen molecules. These colors can be fleeting and appear during strong solar activity, making them less frequently observed compared to other auroral colors.
The aurora borealis, also known as the Northern Lights, is a natural light display in the Earth's sky predominantly seen in high-latitude regions in the Northern Hemisphere. The aurora australis, or Southern Lights, is the same phenomenon but seen in the Southern Hemisphere. They are caused by the interaction between solar winds and the Earth's magnetic field.

The rarest color in auroras is blue. Blue auroras occur at higher altitudes than other colors, around 60 miles above the Earth's surface. They are less commonly seen compared to green and red auroras.
Aurora Borealis and Northern Lights are both names for the same thing.

A red diamond is probably the rarest colour for a natural diamond. Flawless diamonds are the rarest in clarity, and large diamonds weighing in excess of 20 carats are rare.
