18K Rose Gold PVD and Black PVD Tungsten Flat Grooved Band

1. Cut

What It Means: The angles and proportions of a diamond — the artistry behind how it is shaped.

Why It Matters: A precise cut determines how brilliantly the diamond reflects light, directly affecting its sparkle.

Expert Tip: Choose the highest cut grade within your budget — “Excellent” or “Ideal” offers maximum brilliance.

2. Color

What It Means: The presence or absence of color, graded from D (colorless) to Z (light yellow).

Why It Matters: Colorless diamonds are rarer and more valuable. Slight tints are often imperceptible to the eye.

Expert Tip: Grades G–J offer excellent value while appearing nearly colorless when set in jewelry.

3. Clarity

What It Means: The measure of natural internal features (inclusions) and surface characteristics (blemishes).

Why It Matters: High clarity means greater transparency and rarity — though most inclusions are invisible to the naked eye.

Expert Tip: Consider VVS1–VS2 for eye-clean brilliance, or SI1 for exceptional value.

4. Carat Weight

What It Means: The measurement of a diamond’s weight — and indirectly, its size.

Why It Matters: Larger diamonds are rarer, but beauty is more than size — a well-cut diamond of any carat can captivate.

Expert Tip: Focus on cut quality and balance carat weight with brilliance for a lasting impression.
