Those cracks are a common trick of the old Ghalion scribes. The stone was meant to hide a sigil that only appears when viewed from a specific angle, so the fissures act like a natural mask. Look for a circle of seven stars carved faintly near the top—each star’s points often align with the fissures. When you overlay that pattern on your scan, the hidden icon should come through. Good luck, and don't let the cracks fool you.
