In a large bowl, combine flour, sugar, baking powder, lime zest, and salt, whisking well. Using a pastry blender, cut butter into flour mixture until it resembles coarse crumbs. Add papaya, reserving 2 tablespoons papaya for scone centers.
In a liquid-measuring cup, combine cream and vanilla extract, stirring to blend. Add to flour mixture, stirring until mixture is evenly moist. (If dough seems dry, add more cream, 1 tablespoon at a time.) Working gently, bring mixture together with hands until a dough forms.
Turn out dough onto a lightly floured surface. Knead gently 4 to 5 times. Using a rolling pin, roll dough to a ½-inch thickness. Using a 2½-inch flower-shaped cutter, cut 11 scones from dough, rerolling scraps as necessary. Place scones 2 inches apart on prepared baking sheet. Press an indentation into centers of scones with thumb.
Bake until edges of scones are golden brown and a wooden pick inserted in the centers comes out clean, approximately 20 minutes. Let cool on a wire rack.
Spoon Lime Glaze over scones. Divide reserved chopped papaya among centers of scones. Let glaze dry on scones before serving, approximately 1 hour.
