Diamond

Diamond Carat WeightMehmet Doğu2020-04-05T20:37:12+03:00A carat (ct.) is the unit of measurement specifically used to describe the weight of a diamond (or other gemstones). A single carat is equivalent to 0.2 grams, or 200 milligrams, and is divided into 100 points. Don't confuse "carat weight" with "karat," the method of determining the purity of gold. AA certified diamond that comes with a grading report, indicates the exact carat weight to the nearest hundredth of a carat, in decimal format. A 1-carat diamond has 100 points (1.00) while a ¾ carat stone has 75 points (0.75). Carat weight in pre-set jewelry is typically described as a fraction (e.g. ¾ carats) and has an equivalent decimal range (¾ carats = 0.69 – 0.82 points).

The table below correlates fractional sizes with their decimal equivalent:

Carat Fraction	Decimal Equivalent
1/10	.09 – .11
1/8	.12 – .13
1/7	.14 – .15
1/6	.16 – .17
1/5	.18 – .22
¼	.23 – .28
1/3	.29 – .36
3/8	.37 – .44
½	.45 – .58
5/8	.59 – .68
¾	.69 – .82
7/8	.83 – .94
1.0	.95 – 1.05

Carat Weight and Price

Diamonds are mined from deep within the earth's crust. Rough diamonds are either too small or inferior in quality to produce glimmering and polished products. The rarity of larger, high-quality diamonds has resulted in significant price escalations between sizes. For example, a one-carat diamond can command four to six times more than a half-carat diamond.
