Diamond Weight Vs. Diamond Size

0
Let's talk about Diamond Weight Vs. Diamond Size....
One thing that never fails to amaze me is people's wrongly perceived ideas about a Diamonds weight vs what size it will be. Very few people seem to really know the actual size differences between say a 0.75 Ctw stone & a 1.00 Ctw Stone. Have a guess...................................
The actual approximate difference between the two sizes (using a Round Brilliant Cut Diamond as an example) is 0.7 mm, or 0.0275 inches! - who can honestly say that they could tell the difference without seeing both Diamonds up close and sat next to each other?
Something to consider is the fact that certain settings, if used correctly, can make a Diamond appear larger than it actually is. Then of course there's finger size..........it stands to reason that a 1.00 Ctw Diamond Ring will look considerably bigger when worn on a size 4 finger than it would on a size 8.

Some useful examples of Diamond weight vs. Diamond size

(Round Brilliant Cut):

0.25 Ctw - approximately 4.1 mm in diameter

0.33 Ctw - approximately 4.4 mm in diameter

0.50 Ctw - approximately 5.2 mm in diameter

0.75 Ctw - approximately 5.8 mm in diameter

1.00 Ctw - approximately 6.5 mm in diameter

Diamond Weight History - An Interesting Fact

0

Believe it or not, before we had sophisticated measuring devices, the weight of a Diamond was measured against the seeds of a tree! The seeds used were Carob tree seeds (pictured right) and the reason they were chosen was for their amazing uniformity in weight.
One Carat was equal to one Carob Tree Seed (or approximately 200 milligrams). Amazing huh?

How Heavy? Carrots?

It's widely known & understood that a Diamond's weight is expressed in Carats, often confused with the word Karat (the term used to describe the purity of Gold) and rarely confused with the orange vegetable.

Diamonds are always measured to the nearest hundredth of a Carat. Carats are then further divided into points. Points are used to describe Diamonds of sizes less than one Carat in weight. Eg: A hundredth of a Carat is also called a point.

One Carat is equal to 200 milligrams, or 0.2 grams. One ounce is equivaent to 142 Carats.
