4Cs of Diamond | Quality Guide for Diamonds

Expert Guidance for Your Perfect Diamond

Choosing the perfect stone for your forever ring is a meaningful journey, with many details to consider. At our studio, we offer both lab-grown diamonds and moissanite, each selected for their exceptional beauty. For lab-grown diamonds, we give you the freedom to choose your own stone, so it truly reflects your style and preferences. Each diamond is IGI certified, with excellent cut, polish, and symmetry. For moissanite, we use only the highest colour and clarity grades to ensure maximum brilliance and fire. We believe in complete transparency and are here to guide you with honest, expert advice—so you can confidently choose a piece that feels just right for you.

Cut

Cut determines how beautifully a diamond reflects light, creating its brilliance, fire, and sparkle. Unlike other characteristics, cut depends on the skill and precision of the craftsman.

A well-cut diamond reflects light perfectly for maximum sparkle, while a poorly cut one lets light escape, making it appear dull. Diamond cut is graded from Excellent to Poor, with Excellent offering the highest level of brilliance and shine.

Good

Very Good

Excellent

Ideal

Fair

Good quality cut which reflects some light while maximizing weight. While not as brilliant as a good cut, still a quality diamond.

Good

Premium quality cut to optimize the size without sacrificing quality or beauty. Reflects most light that enters.

Very Good

Superior quality cut that reflects nearly as much light as the ideal cut while at a substantially lower cost.

Excellent

Exquisite quality cut to create the optimal combination of brilliance and fire. Reflects nearly all light that enters the diamond.

Ideal

Cut to the most exacting standards. These diamonds have the most desirable dimensions and are proportioned to return the maximum possible light.

Color

Color refers to how colorless a diamond appears, with the most colorless stones being the rarest and most valuable. Diamonds are graded from D (colorless) to Z, with subtle increases in warmth as you move down the scale.

Color can become more noticeable in larger stones and certain shapes. It’s also influenced by your setting—yellow gold, for example, can make near-colorless diamonds appear whiter. Choosing the right color grade is about finding the perfect balance between appearance, design, and budget.

G

G Color Near-colorless. Color noticeable when compared to diamonds of better grades, but offers excellent value.

F

F Color Colorless. Slight color detected by an expert gemologist, but still considered a “colorless” grade—a high-quality diamond.

E

E Color Colorless. Only miniscule traces of color can be detected by an expert gemologist—a rare, high quality diamond.

D

D Color Absolutely colorless or icy white. The highest color grade—extremely rare and most expensive.

Clarity

Clarity refers to how free a diamond is from internal inclusions and surface blemishes. Graded from Flawless to Included, most diamonds have tiny imperfections that are not visible to the naked eye.

The impact of these inclusions depends on their size and placement—those near the center are more noticeable than ones hidden along the edges. This is why each diamond is unique, and choosing one is best done by looking beyond just the certificate

Flawless with no internal or external flaws. Extremely rare and valuable.

Carat

Carat measures a diamond’s weight, with one carat equal to 200 milligrams. However, carat doesn’t always reflect how large a diamond looks—size can vary depending on its cut and shape.

A well-cut diamond can appear bigger and more brilliant than a poorly cut one of the same weight. For better value, choosing slightly below popular carat sizes can offer a similar look at a more accessible price.
