quality
💎 質 = two axes (斤斤) over shell-money (貝): goods weighed for quality
The top doubles 斤, an axe also used as a weight unit; the bottom 貝 is the cowrie shell once used as money. Weighing something against money tells you its true worth, its quality. Sound hook: shitsu starts like sheets, and good sheets are all about quality.
