The 4Cs and how to choose a quality diamond
Choosing a diamond is a subtle balance between emotion and expertise.
Behind every sparkle lies a story, driven by four essential criteria that define a diamond's beauty: Cut, Color, Clarity and Carat. Known as the 4Cs, they help you understand what makes a diamond truly exceptional.
At AGUAdeORO, we work exclusively with cultured diamonds, valued according to the same standards as mined diamonds, with the added advantage of being ethical and sustainable.
We select each stone with care, so you don't need to be an expert to make the right choice. But we also believe in transparency and your ability to choose with confidence.
Cut
The cut is what gives a diamond its brilliance. It's not the shape (round, oval, etc.), but the way its facets reflect light. A well-cut diamond will catch the light with every movement. For us, this is the most important criterion: the cut brings the stone to life.
Color
Diamonds are graded from D (colorless) to Z (yellow or light brown). The closer the color is to D, the rarer and more luminous the stone. At AGUAdeORO, we offer cultured diamonds in the best color categories, for pure, luminous, timeless brilliance.
Clarity
Most diamonds have small inclusions - natural marks formed over time. Clarity indicates how visible these marks are. Flawless diamonds are very rare. That's why we only select stones of excellent purity, with inclusions invisible to the naked eye.
Carat
Carat is a measure of weight, not size. A higher carat may result in a larger diamond, but proportion and cut remain essential. At AGUAdeORO, we help you find the right balance between carat and cut, so that your stone is as beautiful as it is comfortable to wear.
Whether you're dreaming of a delicate sparkle or a bold piece of jewelry, we're with you every step of the way. Each diamond comes with its own certificate, reflecting our total commitment to ethical and responsible luxury.
A diamond is much more than a gem: it's a promise.
And we're here to help you find the one that's right for you.
