The price of any diamond depends greatly of its colour, purity, the existence of inclusions, and of course, the pressure of offer/demand.
A one-half carat diamond weighs 100 milligrams = 0.10 gram.
The weight of a carat is equivalent to 200 milligrams, so a two-carat diamond weighs 400 milligrams.
The raw diamond of 19.5 carats weighs about 3900 milligrams. Remember, though that raw, gem-quality diamonds can lose about 60% of their weight when cut and polished.
This depends entirely on the diamond in question.
It weighs 10 milligrams.
An Asian Tiger Mosquito weighs about 2.5 milligrams.
The average queen bee weighs about 200 milligrams.
An average paper clip weighs about 1.4 grams (or 1400 milligrams)
The diamond either weighs 100 points, or a full carat, or it weighs 80 points or 80/100ths of a carat.
Surely the answer is in the question 400 ounces
Cigarettes vary by weight as much as 10%. But a single cigarette weighs about 1 gram.
Today, on Blue Nile, the smallest diamond weighs .23 carats and is available for US$270.
