Pricing
Larger diamonds are much more rare, thus commanding a higher price/per/carat.
Carat weight affects the value of a diamond by about 10-20% for each step in
size difference. Also, "magic sizes" refer to major carat weight categories,
for example exactly 1.00 carat, or larger, and can prompt "price premiums". To
calculate the price of a diamond you multiply the carat weight by the
price/per/carat. For example: if a 1.25 carat diamond was priced at $10,000
per/carat the diamond would be sold for $12,500.
Choosing The Right Size
In the selection process, most women today aspire to owning an engagement
diamond of at least 1 carat. Statistically, the average size sold for
engagement is between a half and three-quarter carat. The carat weight however,
doesn't necessarily reflect how the diamond appears. The most popular diamond
shapes sold are the Round and Princess Cuts. The outer diameter of a 1 carat
round diamond is about 6.5mm, however if the diamond is cut too "deep" it will
be smaller in diameter, or if it's too "shallow" it will appear larger in
diameter. When you review the section on "Cut Quality", bigger doesn't
necessarily mean better. The final decision is always up to YOU, the consumer.
