How to determine the size of your bracelet

To determine the size of the bracelet you need, use a string, a pencil, and a ruler. Wrap the string around your wrist so that it goes all the way around, then use the pencil to mark where the two ends of the string meet. Then, take the string and measure its length using your ruler, in inches. Here is a size chart.

Size of your wrist	Size you should take
5 inches and a half	6 inches
6 inches	6 inches and a half
6 inches and a half	7 inches

Carat

Carat is a measurement of weight for diamonds and other precious stones. To give you an idea of the size of a carat, it is also possible to measure it in millimeters, as shown in the table below. Larger diamonds are much more difficult to create in a laboratory and, therefore, are more expensive.

To give you an idea, here are the measurements in millimeters for different diamond shapes :

Carats	Round	Oval	Radiant/Emerald	Princess	Pear
0.25 ct.	4 mm	5 x 3 mm	4.3 x 3 mm	3.25 mm	5 x 3 mm
0.50 ct.	5 mm	6 x 4 mm	6 x 4 mm	4.5 mm	6 x 4 mm
