Diamond Education

Everything You Need to Know Before Saying "Yes"

At Charleston Rings, we believe every diamond tells a story—and yours should shine as bright as your love. Whether you’re shopping for an engagement ring or a meaningful gift, understanding what makes a diamond unique will empower you to choose the perfect one.

The foundation of diamond grading

The 4 Cs of Diamonds

1. Cut

The cut refers to how well a diamond's facets interact with light. A well-cut diamond sparkles brilliantly, while a poorly cut one appears dull. Remember, a diamond's cut is about craftsmanship—not its shape.

2. Clarity

Clarity measures the presence of internal or surface imperfections (called inclusions and blemishes). Diamonds are graded on a scale from Flawless (no imperfections visible under magnification) to Included (imperfections visible to the naked eye).

  • VS1 - VS2: Nearly flawless and a great balance of quality and value.
  • SI1 - SI2: Slight inclusions, often invisible without magnification.

3. Color

Diamond color grading ranges from D (colorless) to Z (noticeable yellow or brown tint). Colorless diamonds are the most valuable, but near-colorless diamonds (G-H) can look stunning and cost less.

4. Carat Weight

Carat refers to a diamond’s weight, not its size. Larger diamonds are rarer and more expensive, but carat alone doesn’t determine beauty. A well-cut smaller diamond can outshine a larger one.
