If an emerald weighs 3.50 carats and costs $10,500, what is the price per carat?

To find the price per carat, you divide the total cost of the emerald by its weight in carats. In this case, the emerald costs $10,500 and weighs 3.50 carats.

When you perform the calculation:

Price per carat = Total cost / Weight in carats

Price per carat = $10,500 / 3.50

Calculating this gives you:

Price per carat = $3,000.00

Thus, the correct choice indicates that each carat of the emerald costs $3,000.00. This price per carat is a useful metric in the gemstone market, providing a standardized way to compare the value of different gems based on their weight. This understanding is crucial for valuation and investment considerations in colored stones.
