Preheat your oven to 350°F (175°C). Place your pie crust into a 9-inch pie pan, crimping the edges as desired to create an attractive border.
Evenly spread the pecan halves across the bottom of your prepared pie crust.
In a medium bowl, whisk together granulated sugar, light corn syrup, melted butter, eggs, vanilla extract, and salt until smooth and well combined. Pour this mixture over the pecans.
In a small microwave-safe bowl, combine semi-sweet chocolate chips and heavy cream. Microwave in 20-second intervals while stirring in between until you achieve a smooth consistency.
Drizzle the melted chocolate over the pecan filling in your pie crust. Use a knife or spoon to gently swirl it into a marbled effect.
Place your pie in the oven and bake for 50-60 minutes until set but slightly jiggly in the center. Allow it to cool completely for at least two hours before slicing.
