The Four C’s: Part One – Carat
Thursday, July 21st, 2011
- Introduction
When selecting a diamond engagement ring, there are many factors to consider prior to making a purchase. The task might seem daunting at first, but with a little bit of knowledge you can walk into any showroom feeling confident in making an educated purchase. When evaluating a diamond, it is best to look at the carat, color, clarity, and cut.
- What is a carat?
Contrary to popular opinion, carat (ct) actually refers to the weight of the diamond and not the size. Typically when discussing stones of less than one carat, jewelers talk about the stone in terms of points. This is because a carat is divided into 100 points, and thus .01 carat would equal one point. For instance a ½ carat stone would be referred to as 50 points. This analogy doesn’t always prove to be true because diamonds cannot be all uniformly cut to an exact carat, or half carat, so oftentimes the carat weight (1/4 carat, 1/2 carat, etc.) is an estimate of the actual weight of the diamond. For instance a ¼ carat stone can refer to a stone range anywhere between .23 – .27 carats.
- How does weight affect price?
Diamonds become rarer as their weight is increased, and as such, the more valuable and costly each stone is. The larger the stone, the more the cost in carat increases at an unbalanced rate. For instance, a 2-carat diamond is always more expensive than two 1-carat diamonds that are the exact same quality. It is crucial to note that when assessing a diamond, weight and size are not the same thing.
- What to keep an eye on
For centuries diamond cutters have sought to produce a diamond with the highest possible weight while not sacrificing quality from the rough diamond. It’s easy to say that bigger must inherently be better, but you really need to consider what is right for you. The quality of the diamond, which we will cover in a successive blog post, must also be considered in addition to budget.
