Carat Weight

A diamonds weight is measured in carats and is the easiest of the 4 C’s to measure. A carat is equal to 100 points or approximately 0.2 grams. The higher the carat weight the more valuable and rare the diamond. It is worth noting that a 2ct diamond will be more valuable than two 1ct diamonds as finding larger rough diamonds is not as common.

A diamond will increase in weight much faster than it increases in actual face up diameter. An ideal 1ct will measure approximately 6.5mm in width, whereas a 2ct diamond will measure approximately 8.2mm width. The proportion of weight increase is not proportional to the appearance size increase.

When selecting carat weight consider factors such as:

• Personal preference
• Finger size
• Practicality
• The characteristics of the other diamond elements which will compliment the size of the diamond

Ultimately the diamond you purchase should be chosen based on personal style and budget. If the diamond is being purchased as an engagement ring then try and gain an understanding of what your partner likes and even ask friends and family for advice.
