The Four C's of Diamonds: Carat
Carat is the easiest of the Four C's to explain, and the one that moves the price fastest. Here's how carat weight relates to size and cost, and how to get the most diamond for your budget.
Carat is weight, and weight means size
A diamond's carat weight is a direct indicator of its size: the more it weighs, the larger it is. Price rises with carat weight, but not in a straight line. A 5 carat diamond doesn't cost five times as much as a 1 carat diamond; it can cost 100 times as much or more.
So when you shop, think about the curve of size against price, decide where on it you want to be, and trade off the other three C's to stay within your budget.
Getting the most size for your budget
Size on the hand isn't only about weight. How a diamond is cut decides how much of its weight shows from above, and shape matters too: ovals, pears and marquises tend to look larger than a round of the same weight. A well-chosen setting can add presence as well.
Dealer tip
Diamond prices tend to step up at round weights like 1.00 or 2.00 carats. A stone just under one of those marks can look virtually the same on the hand for noticeably less. We'll show you where those trade-offs land for your budget.

Photos can't show how a diamond looks on your hand. We'll shortlist stones that fit your budget and show you the best few side by side, in person in Downtown LA or by video call.
