Preheat the oven to 400°F (200C/180C Fan) and line a baking sheet with parchment paper or a silicone baking mat.
In a large bowl, mix together the flour, baking powder, salt, spices and sugars.
Add the chopped cherries and chocolate chips, stir through the flour mixture.
Slowly add the heavy cream, a little at a time until the mixture comes together into a dough. You will likely need between 1 and 1¼ cup. Reserve the remaining cream to brush the top of the scones before baking.
Once the dough has come together, tip out onto a lightly floured surface and knead lightly once or twice to form a round. Press this into a circle, roughly 8" round and 1" thick.
Using a sharp knife or dough scraper, cut this into 8 triangles (like pizza slices).
Place these a couple inches apart on the baking sheet and brush with the reserved heavy cream. Top with extra chocolate chips and/or coarse brown sugar (optional).
Bake in the preheated oven for 15 minutes until lightly golden. Remove from the oven and cool on a wire rack.
