Nautical star

It is usually rendered as a five-pointed star in dark and light shades counterchanged in a style similar to a compass rose.

[1][2] The United States Coast and Geodetic Survey started using this symbol in its double-circle compass roses around 1900.

The symbol recalls both the five-pointed star of the US national flag and the color pattern of the compass rose found on many nautical charts.

[11] A nautical star may symbolize protection, guidance, and good luck,[9] or metaphorically represent finding one's way home when lost in life or travel.

[11] In the 1950s, some lesbians in Buffalo, New York wore a blue five-pointed star tattoo on the wrist, a location that could be covered by a watch.
