In Pokémon Crystal (GBC), there is no Heart Scale item. The Heart Scale item was introduced to the Pokémon video games in Generation III (3) (Ruby/Sapphire/Emerald). Thus, you cannot get the Heart Scale in Crystal. There is no Generation II-III trading, so there is no possible way to use the Heart Scale in Pokémon Crystal Version, sorry!
