𝛁

U+1D6C1 "𝛁" Mathematical Bold Nabla is a typographic variant of the traditional nabla symbol (∇), rendered in a bold typeface and intended for use in mathematical and scientific notation, particularly within documents that require clear distinction between different styles of symbols. It is part of the Mathematical Alphanumeric Symbols block, which was designed to provide separate code points for bold, italic, and other styled versions of standard letters and symbols to support precise formatting in electronic text without relying on font styling. This bold nabla is commonly used to denote the vector differential operator, often called del or gradient, in contexts where boldface is needed for visual emphasis or to conform to specific mathematical conventions.
