The value of the Sky-Cleaving Greatsword was hard to judge.
Considering the gemstone settings, the price difference between sapphires and rubies was not significant. Seen purely as a gemstone weapon, it was on the same level as the Crimson Blood Sword.
Compared to the Earl's longsword, which had two gems embedded, there was quite a gap—setting a single gemstone was manageable, but embedding two required much more skill to coordinate without interference between the stones.
However, the Sky-Cleaving Greatsword was not a standard gemstone weapon.
The hilt was carved with a magic array, a feature of magic equipment, which, with the blessing of the array, allowed it to better leverage the power of the sapphire.
In addition, the sword's blade was made from the bones of an intermediate magical beast mixed with magic metal fine gold. This material was significantly better than the fine steel of the Crimson Blood Sword, which had been mixed with mithril.
