Kathleen Quain was so unlucky to meet the master craftsman who carved this jade.
"Nonsense! This belongs to the Quains. How could it belong to the Abbot's?" Kathleen argued loudly.
It was a typical bluff.
The master craftsman frowned, and took the magnifying glass to check the jade, finding that there was an extremely small groove at the top of the jade pendant.
There were also words engraved in the groove, so he was more convinced that this was the jade he had carved back then.
"It is obvious that this belongs to the Abbots. When did it become something that belongs to the Quains? Little girl, this is the evidence!"
The master craftsman sent the jade pendant to the boss and let the boss look at that special sign.
Generally, things that represented the family would have a special mark. The boss had a look and recognized that this piece of jade belonged to the Abbots.
