♦️ is usually called "rhombus" or "diamond". It can represent the geometric shape of a rhombus and is used in many scenarios to refer to objects with a rhombus - like appearance, such as rhombus - shaped signs, patterns, decorations, etc. It can also appear as a basic shape element in some specific designs, artworks or signage systems.
I saw a necklace in the shape of a ♦️ when I went to the shopping mall today.
The exterior of this building has a lot of elements of ♦️.
