The weight (and therefore the size) of stones used in diamond jewellery is measured in carats. They are a very old measure, and these days carat weights are the standard for precious stones. For precious metals like gold, carat is a purity measure rather than an outright weight, so that is slightly different. In diamond rings, the carat value stated may be the weight of the centrepiece stone or the combined weight of all stones including small chips- fell free to ask if in any doubt about any of our diamond jewellery.
Back in the early days of diamond trading for jewellery, the stones were measured against the weight of carob seeds, which are remarkably uniform in size and weight. One carob seed came to be one carat. There is a finer measurement called ‘point’. One point is one hundredth of a carat, so a half carat diamond is a fifty point diamond.
While size certainly does matter, diamond quality is also important. Clarity and colour will also affect the price and desirability of a given stone. So will the type of cut.
One carat is 0.2g. That doesn’t sound like much, but one carat diamond engagement rings are actually quite good and the central stone in question will probably look quite impressive. Most of the stones used in diamond jewellery are smaller than that. A 2 carat diamond is on the decidedly large side, and a 3 carat diamond is truly outstanding in size. Good quality loose stones of that weight are usually sold for tens of thousands of pounds when cut, or more.
