A 4 carat diamond ring is a balanced beauty

These stones have the perfect balance between large size and subtle appearance at the right price.

The varying quality of each of the 4Cs determines the price of a diamond. Carat is one of the 4cs and the most easily understood: it is the weight of the diamond. However, carat is often confused for karat – a measurement of purity for gold – or for a unit of size. Carat weight does affect the size of a diamond but not proportionately. Just as the weight of a person can indicate height, but not determine it precisely.
