Diamonds By The Carat: Large Is Rare
We weigh diamonds in carats. A carat is a metric measurement of 200 milligrams. That means 5 carats equals a gram. Most people will never own a gram of diamonds. While a large diamond is rare, a really large one is extremely rare. Also, most diamonds mined in the world will not be of a quality to become gems, and may be used for industrial purposes. Thus, there aren’t many gem quality diamonds
One carat is a good sized diamond, makes an impressive statement, and is larger than most people will ever own.
Two carats, that much rarer than one carat, has a value that is about twice the value, per carat, of an equivalent one carat gem, all other things being equal. Meaning that a two carat diamond is at least twice as rare as one carat, and a two carat diamond will be four times the price of an equivalent one carat (twice the price per carat, plus twice the carats).
As each new carat weight is reached, there can be an increase in price per carat.
Looking at the diamonds as they increase in size, the diamond becomes rarer and rarer.
Most people will never even see a 5 carat diamond, let alone OWN one!
There is no question of the obviously impressive visual impact of larger diamonds
A seven carat gem is a similar price per carat to five and six carat weights.
Once we get to ten carats, it it enough to make people stop in their tracks. The price per carat really jumps, because ten carats is so rare.
In the Spring 2017 Important Jewels auction, there are six diamonds with a weight greater than 10 carats.
What more is there to say? A pair of earrings: Two diamonds with a total of over 27 carats!
