What affects diamond prices?

As mentioned above, the four C’s are the most important components of any diamond.

Here’s a breakdown if you’re not familiar with these terms…


Diamonds are found in a variety of colours but the most valuable are the pure diamonds, appearing almost colourless.


The value of your diamonds will depend largely on the clarity of the stone, where higher clarity grades are naturally more valuable.


The cut refers to the proportioning and polishing of the diamond. The most popular diamond cut is the modern round brilliant cut, whose proportions and facet arrangements have been perfected by mathematical and empirical analysis.


This refers to the weight of your diamond and we prefer diamonds of at least 0.50 carats, but exceptional stones above 0.30 carats will be considered.
