Engagement rings in Hatton Garden: The importance of carat weight


When exploring Hatton Garden’s many jewellers, one of the first things that becomes apparent is the variation of carat weights on offer. Carat is the standard unit of weight for diamonds. A metric carat is equivalent to 0.20 of a gram. This in turn is divided into 100 points, so a half carat stone might also be referred to as 50 points or 0.50 carats. The expression of a stone’s weight in carats dates back to ancient times when gems were measured using the weight of a carob seed.


When viewing beautiful engagement rings in Hatton Garden, it is important to remember that carat is a measurement of weight and not size. As an example, a half carat diamond might have a diameter 5.1mm, whereas the diameter of a one carat diamond (weighing 100% more) will only increase by a further 25%.


Our Hatton Gardens jewellers are often asked of the importance of carat weight when it comes to GIA graded diamond engagement rings. This is a very personal choice and one that requires considerable thought. For some customers, the larger the diamond the better. For others a more modest sized stone of a higher quality is preferred. Whilst a larger diamond is many times rarer and thus more valuable than a smaller diamond of the same quality, it is essential to take proportion into account when viewing engagement rings in Hatton Garden. Ideally the size of the diamond should not become lost on the hand, nor should it be overpowering. Finding the perfect carat weight therefore requires a little bit of experimentation when trying on engagement rings in London!
