What is an ounce of diamond worth?

Answer 1

A one-ounce diamond is equal to a stone that measures more than 141 carats. This would be an exceptionally rare, large and precious stone.

Please review this list of diamonds, below, to find a large stone, and research its value.

Answer 2

The value of this weight of diamond depends on whether the stones are loose or the weight represents a single stone. It also depends on whether you're pricing gem stones or industrial diamonds, which are about 80% of all diamonds mined.

For gem stones, the cut, clarity, carat weight and colour of the stone(s) will determine its/their value.

Mathematically, one ounce equals 28.3495231 grammes. One carat of diamond equals .20 grammes. (28.3495231 grammes/.20 (per carat) = 141.7476~ carats.) This means that you would need to find a single diamond weighing 141 carats, or find a combination of stones to equal that weight and then price them.

A 110 carat (total weight) diamond necklace, sold recently at auction, in the estimated range of US$250,000 - US$260,000. A single stone of 141 carats would not only cost many millions of dollars and be hard to find, but would be best exhibited in other than jewelery, because of its size.

If you're buying industrial diamonds, you can purchase a bag of these diamonds for about the price of a latte, if you purchase in bulk quantities on a regular purchase scheme.

Answer 3

One carat of diamond weight weighs .20 grammes. Then, .20 g = 0.007054 oz. Can you do the math?
