Diamond Weight (Carat)

The carat is a unit of measurement used to weigh diamonds. One carat is equal to 200 milligrams, or 0.2 grams.

The origin of the word “carat” is from the carob seeds that people used in ancient times to balance scales. In fact carob seeds are so uniform in shape and weight that even today’s sophisticated instruments cannot detect more than three one-thousandths of a difference between individual seeds.

The diamond forming process happens only in exceedingly rare circumstances, and typically the natural materials required are only found in small amounts. Because of this That means that larger diamonds are uncovered far less often than smaller ones. Thus, large diamonds are very rare and have a greater value per carat. This is the reason that the price of a diamond rises exponentially to its size, so a 2 carat diamond will cost more than two 1 carat diamonds.

Best Diamond Sizes to Buy

When buying diamonds the first thing you should do is work out your budget. A tradition rule of thumb when buying a diamond engagement ring is to buy a ring worth around two months salary. Of course this is just a guideline, it’s not carved in stone and your first consideration should be not to spend more than you can comfortably afford.

The decision on the carat weight of a diamond is really more about striking a balance between size and quality. If you (or your partner) prefer larger jewelry items, and you are working within a budget, you can still find a larger diamond of excellent quality gem by selecting one which is graded slightly lower in terms of either color or clarity, or a combination of both.

You should also remember that slim fingers will make small diamonds look bigger. If a woman has small fingers, a 1-carat diamond will look proportionately larger – and an even larger stone may appear stunningly huge.

You should also think about what sort of setting will hold the diamond. Make sure that the ring, or jewellery setting you choose is made to fit the carat weight of the diamond you buy.
