Fine, micro‑cracks are basically the personality of a statue. If you’re all about stability, use a low‑viscosity marble cement, fill the chips, let it set, then polish a bit so the seam is invisible. That’s the “tune‑up” route. If you want the original soul intact, just clean the cracks with a soft brush, maybe a drop of clear resin to keep the water out, and leave the rest untouched. Don’t obsess over perfect color matching – the character shows in the flaws. In short, fix enough to stop it from falling apart, but don’t erase the story the cracks are telling.
