It’s a popular misconception, but the carat of a Diamond is actually a measure of its weight, not its size.
It’s actually the Diamond’s physical weight measured in metric carats – with one carat equivalent to 0.2 grams. Carats are then even further subdivided into 100 equal points – so for example 50-points equals half a carat.
It will be no surprise to you that as a Diamond’s weight increases so does its value, and a 3-carat Diamond is worth substantially more than three individual 1-carat Diamonds.
The chart on the right will give you an appreciation of what weights and approximate sizes are available for your new Diamond.
SO WHERE DID THE TERM ‘CARAT’ COME FROM?
Originally Diamonds were weighed in comparison to the seeds of the carob tree and the word carat is a derivative. Because these small seeds had a fairly uniform weight the early gem traders used them as counterweights on their balance scales. Thankfully we’re a little more scientific and precise with our measurements today!
Choosing the right Diamond is an immensely personal decision. Do you go for carat over colour; clarity over cut or vice versa? Really it’s all about personal preference and how the Diamond meets your expectations.
But one thing is for sure – there is a Diamond for everyone – and whether it’s big or small – clear or slightly coloured – they’re always unique and very precious.
