Seamless Ring Placement Edit

I have a high-resolution photograph of a hand, and I need a realistic, seamless edit that places a ring on the ring finger. The final image should look as though the ring was captured in-camera—proper scale, matching lighting, natural shadows, and no visible retouching marks.

Please use professional-grade tools such as Adobe Photoshop (or equivalent) and keep the edit fully non-destructive. I’ll need:

• A layered PSD showing all adjustment layers and masks
• A flattened PNG or JPG in the original resolution

Turnaround within 24 hours is ideal, but let me know upfront if you need a bit more time.
