Frequently Asked Questions About carat

What is the difference between carat and karat?

These two words are tricky

as one of them may refer both 

to the measurement of a precious stone's weight 

and to the purity of gold

while the other only refers to the purity of gold

Carat may be used for both

but karat is only employed in reference to gold.

 

What is weighed in carats?

Precious stones are weighed in carats

a single carat is equal to 200 milligrams. 

Carat is also a variant spelling of karat, 

which measures the purity (but not the weight) of gold.

 

How much is a carat?

If carat is serving as a variant spelling of karat, 

then it is measuring the fineness

rather than the weight, of gold

each carat is equal to 1/24 part of pure gold

 

If carat is being used in reference to precious stones

it is a unit of weight equal to 200 milligrams.

Usage Notes

'Carat' vs. 'Karat' (vs. 'Caret')

What to Know

carat is a unit of weight used to measure the size 

of a gemstone such as a diamond

 

karat is a measurement indicating 

the proportion of gold in an alloy out of 24 parts,

so, 18K gold is 18/24 parts gold

 

However, the use of carat (in place of karat)

to indicate the fineness of gold is also considered acceptable.

 

The idea that bigger is better 

when it comes to precious stones was around long before 

the dawn of precise instruments for measurement

 

So, hundreds of years ago

when people needed some standard for weighing their gems

they turned to the carob tree. 

Since the carob's seed weighs approximately 

the same as the smallest gemstone

it was designated as the base unit for weight

and since the seed was called carat, 

the name came too:

any stone that approximated the weight of one seed 

was deemed to weighone carat.

 

Carat vs Karat

The name carat derives, via Medieval French and Italian

from Arabic qīrāṭ, meaning "bean pod," 

which is itself from Greek keration,

referring to both the carob bean and a small weight

Early in the 20th century,

the weight of the carat was set at 200 milligrams, or 0.2 grams

Thus, a 2-carat diamond weighs 400 milligrams or 0.4 grams.

 

The word karat is ultimately from the same source as carat 

but came to refer to the fineness of gold

one karat is equal to 1/24th part of pure gold in an alloy. 

(The 1/24th proportion goes back to ancient Roman times 

during which a siliqua was equal to 1/24th of a golden solidus.  

But you already knew that.)

 

In other words, 

a 14-karat gold ring consists of 14 parts gold 

and 10 parts of some other metal, like copper; pure gold is 24 karats.

 

Although carat and karat have distinct meanings in the jewelry world,

the words are frequently confused

 

Here are a few examples 

showing karat being used to indicate the weight of a diamond 

instead of the purity of gold.

the buckles are made of sterling silver and 14K gold

Some of them have a 0.10 karat diamond toward the center.

The substitution of karat for carat in regard to precious stones 

is considered incorrect,

whereas the reverse

using carat in place of karat to indicate the pureness 

or fineness of goldis considered acceptable. (English strikes again.)

 

This use of carat as a variant spelling of karat 

in the assessment of gold goes back to the 16th century

so its acceptance in contemporary English is understandable.

 

Today, we commonly encounter both carat and karat 

in reference to fine jewelry

where size and quality are emphasized

with carat usually designating the size of a stone 

and karat designating the proportion of gold in an alloy.

 

It should also be noted 

that karat is often abbreviated K, 

as in "an 18K gold ring," 

but carat is almost always written in full.

 

One Extra: Caret

An altogether different homophone is caret

the name for the wedge-shaped mark (^) 

that is used by copy editors and proofreaders 

to indicate the place where text is to be inserted.
