What should you look for when searching for a diamond?

Feel like you could use a little diamond education? LaRog makes it easy to understand what you’re looking at—and looking for. Getting the best diamond at the best value comes down to knowing the “rock talk” (what jewelers call the Four Cs). We’ll explain it all to you when you visit. But for now, here’s an overview to get you started.


Cut is the single most important factor in bringing out the fire and brilliance of a diamond. Diamonds cut to precise proportions are better at bouncing light from one facet to another. It’s a very fine art. Cut the angle too deep, and the diamond looks dark; cut it too shallow, and the diamond looks watery. It takes a true master craftsman to cut a diamond with the absolute precision needed to release its full sparkle and light-reflecting qualities.


Too Shallow - Light is lost out the bottom.

Too Deep - Light escapes out the sides.

Ideal Cut - Maximum provides sparkle in a diamond!



Until you compare diamond to diamond, you might not realize there’s a difference in color. But it can be dramatic. Diamonds are graded on a color scale that ranges from D (colorless) to Z (light yellow). The most expensive diamonds are found at either end of the scale, because—you guessed it—those are the most rare.


Most diamonds contain natural, crystal-like “inclusions.” The number, size and position of these inclusions affect the stone’s value. The clearer a diamond, the more rare—and you already know the connection between rarity and price. The diamond clarity scale ranges from Fl (flawless) to I3 (many inclusions visible to the naked eye).

Carat Weight

Diamond weight is measured in carats (100 points in each carat, and five carats in a gram). So, should you go for the biggest rock possible? It depends. Larger diamonds are more rare, which generally makes them more valuable. The tricky part is that size alone doesn’t determine beauty and brilliance. Two diamonds with the exact same carat weight could have totally different values, depending on their cut, color and clarity.

And last but not least, a word about shape.

This one is easy: no single diamond shape is “better” than any other. Just pick the one you like best! Every diamond shape is cut to bring out the most fire and brilliance. Facet shape varies with each cut, so they do filter light differently; and some shapes look better with certain settings. But no matter what shape you choose, if your diamond is well cut, its brilliance and beauty will last a lifetime.
