How Carat Weight Affects Price
The weight of a diamond is given in carats. One carat is
equal to 1/142 of an ounce. Many people think of carat weight as the
size of a diamond. However, two diamonds of the same weight can
look very different in size. If a diamond is cut deep and narrow,
it will look much smaller than another diamond of the same weight
that is cut shallow and wide.
There are two major considerations when looking at the weight
of a diamond:
Price per carat
goes up as the weight goes up, and prices leap at certain critical
Each of the following
weights (starting with 0.46 carats) have entirely separate price
charts, and increase dramatically at each break. Prices increase
because larger stones are much more rare than smaller ones. Therefore,
two smaller diamonds will not cost as much as one diamond that
weighs the same as both together. For instance, two 0.50-carat
diamonds as listed below would cost $3,600, while one stone weighing
1.00 carat would cost $6,600.
Prices given below
are for a Round Brilliant shape, good make, G color, VS2 clarity,
from the Rapaport Diamond Report for March 2000. We give just
one quality as an example to make this point clearly. Other qualities
will vary dramatically in price. Also, these prices are not meant
to represent actual selling prices, since we can always help
you find prices below these.
Example prices for Round / G / VS2:
0.46 - 0.49 Price per carat: $ 2,800
0.50 - 0.69 Price per carat: $ 3,600
0.70 - 0.89 Price per carat: $ 4,700
0.90 - 0.99 Price per carat: $ 5,700
1.00 - 1.49 Price per carat: $ 6,600
1.50 - 1.99 Price per carat: $ 8,400
2.00 - 2.99 Price per carat: $ 10,200
3.00 - 3.99 Price per carat: $ 11,600
4.00 - 4.99 Price per carat: $ 13,000
5.00 - 5.99 Price per carat: $ 16,700
Above 6 carats, diamonds
are considered specials, and are individually priced.
(Hint: If you want to save money, consider a diamond that is
just under the weight/price break. It will look just as large,
but cost less. Example: 0.95 carats instead of 1.00)
are more expensive and harder to find in specific qualities.
Each week, prices
and availability fluctuate for certain sizes and shapes, with
the forces of demand and supply. At the time of this writing
and for a couple of years now, diamonds have been harder to find
in the 1.25 carat range as well as 0.67 and 2.50, to mention
only a few.
This scarcity of certain sizes influences prices for those stones
because the best possible discounts to dealers are not offered
on diamonds that are in limited supply. In other words, a dealer
who has stones of these hard-to-find sizes can just sit on them
until someone offers to pay his price.
We recommend choosing
sizes that are in good supply, to avoid unnecessary premiums.
If you must go down in size and budget a little to get a better
value, apply the rest to your honeymoon or wedding arrangements
and enjoy the savings.
