A Guide to Diamonds: Understanding True Quality

A diamond's beauty is immediate — but its quality is something deeper.

Behind every stone is a balance of precision, rarity, and careful selection. At Halo & Crown, we believe you shouldn't need to study diamonds to wear one with confidence.

That's our role

The Four Cs: What Really Matters

You may have heard of the "Four Cs": Cut, Colour, Clarity, and Carat. These are the universal standards used to ro assess a diamond's quality.

Cut: The Source of Brilliance

Cut is what determines how a diamond interacts with light.

A well-cut diamond reflects light internally, creating brilliance, fire and sparkle.

At Halo & Crown, we prioritise cut above all else, ensuring every diamond performs beautifully in real-world lighting.

Carat: Presence, Not Just Size

Carat refers to weight — but the visual impact of a diamond depends on proportion and cut.

A well-balanced diamond will appear larger, brighter, and more refined.

Clarity: What You Don't See Matters

Clarity refers to the natural characteristics formed within a diamond.

While most are microscopic, they influence both rarity and value.

We categorise our diamonds with a simple principle:

• VS ( Very Slightly Included) — Minor inclusions, dificult to detect

• VVS ( Very Very Slightly Included) — Extremely rare, nearly flawless

Every diamond we use is eye-clean, meaning no visible imperfections to the naked eye.

Because ultimately, what matters is what you see—not what requires magnification.

Colour: The Purity of Appearance

Diamonds are graded based on how colourless they appear.

• Colourless (D - F) — Exceptionally rare. Bright, icy, and highly sought after.

• Near Colourless (G - I) — Appearing white to the naked eye, offering excellent value without compromising beauty.

• Faint Tint (J and below) — A subtle warmth ma be visible, particularly in certain lighting.

Halo & Crown focuses on colourless and near-colourless diamonds— ensuring a clean, crisp, appearance in every piece.

Flourescence: A Subtle Characteristic

Florescence refers to how a diamond reacts under ultraviolet (UV).

Some natural diamonds emit a soft glow— most commonly blue.

In most cases, flourescence has no visible effect in normal lighting.

Halo & Crown may include diamonds with faint to medium flourescence where appropriate — allowing us to offer exceptional beauty while maintaining value.

Lab-grown diamonds typically do not exhibit flourescence in the same way, as they are created under controlled conditions.

Our Standard

Every diamond used by Halo & Cround is selected to meet strict criteria:

• Eye-clean clarity

• Premium colour ranges

• Excellent Light performance

What This Means for You

With all this in mind, the process becomes simple.

You don't need to compare certificated or analyse grading charts.

You can trust that every Halo & Crown piecehas been created with intention— so your only decision is whether it feels right.
