She knew that diamonds are a nonrenewable resource, making them scarce.

Explanation: Cecilia used the economic concept of scarcity (and supply/demand). The new mine caused a temporary supply increase and lower prices, but because diamonds are scarce and remain in demand, their long‑term value/investment potential is likely to hold—so buying at the dip is savvy. (Options 3 and 4 are incorrect; option 1 is true but less explanatory than scarcity for investment reasoning.)
