Step-by-step explanation:
The largest diamond in the world, the Cullinan, weighed nearly 3,107 carats (before cutting).
To convert carats to grams, we can use the conversion factor that 1 carat is equal to 0.2 grams (1 carat = 0.2 g).
Therefore, the weight of the Cullinan diamond in grams is:
- 3,107 carats x 0.2 grams/carat = 621.4 grams.
So, the Cullinan diamond weighed approximately 621.4 grams before cutting.
