Carat Diamonds

Diamond carat may play a key role in your decisions when you’re perusing the array of gems on offer. After all, this particular characteristic has a huge impact on the appearance and value of diamonds. If you want to know more about this aspect of the precious stones, take a look at the following diamond carat guide.


What is a carat?

The word carat derives from ancient times, when carob seeds were used to measure the weight of diamonds. At the start of the 20th century, the system was standardised and it was determined that one carat was equal to 0.2 grams. To make more accurate descriptions possible, this measurement was further divided into 100 points. For example, a 25 point diamond is equal to 0.25 carats, or ¼ of a carat.

If a piece of jewellery contains more than one of these precious stones, for example a multi-stone diamond ring, the stated carat for that product reflects the weight of all the stones combined, rather than each individual gem.

It’s important to note that higher carat diamonds are much rarer than smaller stones, and this is reflected in the prices of the items. You might expect a one carat gem to be worth twice as much as a 50 point or ½ carat stone. However, in actual fact the one carat diamond is likely to be worth more than double the amount, even if it has a similar colour, cut and clarity.


Is carat the same as size?

It’s tempting to equate carat to size. After all, generally speaking, the heavier these objects are, the bigger they appear. However, there is not a direct correlation between these two variables. It is possible for one diamond to look bigger than another but weigh less. Certain cuts and mounts can give these gems the appearance of being larger than their carat weights. This is something to bear in mind when you’re looking for that perfect item of jewellery.


Other considerations

Although carat is a major factor to consider when you’re buying diamond rings, pendants, earrings and other objects, it’s just as important to think about the colour, cut and clarity of the gems. These features also have a huge impact on the overall appearance of the precious stones.

Meanwhile, you should always ensure that the diamonds you buy come from respected and verified sources and have the appropriate certification. If you purchase your items from Marlow’s Diamonds, you can rest assured that you’ll benefit from the very highest standard of gem.
