What ⧪ means
It combines a diamond shape with a downward direction. Here, “black” means the diamond is filled rather than outlined; the character can still appear in any text color. The arrow supplies the downward part of the design.
In mathematical writing, that description identifies the sign without assigning an operation such as subtraction or a decrease. To interpret an expression containing ⧪, look for the author's definition of the sign. When transcribing it, keep the single character: typing a separate diamond and arrow produces different text.
