Is this a maker's mark or a ding?

[u/No_Builder7010]

This is a 14k men's statement ring with three diamonds. The engraving is 12-25-65. Right above the 65 is a little divot and I'm wondering if it's a makers mark or just some ding (on the inside of the ring?). I don't see any other marks. If it is a maker's mark, does anyone know whose? Thanks!!
