How much money would you get if you found 1 pound of real diamond in Saskatchewan?

If indeed you could find such a cache, be aware, that right out of the ground, on average, 75% of the diamonds would be industrial diamonds, which do not have gem-stone quality or value. (If 100% of the cache is industrial grade, the commercial value could be about US$1.60 for all 16 ounces.)

Of the remaining about 25% of the diamonds, most will be about the size of a pin-head; few will be the size of a pea vegetable, and only if you're extremely lucky -- and the seller extremely unaware -- would you find any particular raw stone of any significant value.

When cutting any gem-quality stone, you'll lose about 60% of its carat weight.

Theoretically, if your cache contained a single stone which could be cut to one carat of D colour, Flawless clarity with an Excellent cut, as a gem-quality diamond, it could be valued between US$13,000 and $47,000.
