Choosing Your Diamond: A Simple Guide to Buying a Natural Diamond

A Clear Path to Finding the Perfect Diamond

Buying a diamond can feel overwhelming, but it doesn’t have to be.
Whether you are choosing an engagement ring or another meaningful piece of jewelry, understanding the basics will help you make a confident and informed decision.

💎 What Affects a Diamond’s Price?

Diamonds vary greatly in quality, and their price is primarily determined by the Four Cs: Carat, Color, Clarity, and Cut.

1. Carat Weight

Carat refers to a diamond’s weight. One carat equals 100 points, so a 0.50-carat diamond weighs 50 points.
Larger diamonds are rarer and more expensive, but a smaller diamond with better quality can sparkle just as beautifully.

2. Color

The less color a diamond has, the higher its grade and value.
Diamonds are graded from D (colorless) to Z (light yellow).
Stones graded D–F are considered colorless, while G–H diamonds are near-colorless and offer great beauty for their value.

💡 Tip: A diamond set in yellow or rose gold may appear whiter, letting you choose a slightly lower color grade while maintaining a bright, beautiful appearance.

3. Clarity

Clarity refers to natural inclusions or blemishes inside the diamond.
Most diamonds are not flawless, and that’s completely normal.
Here’s a quick overview:

  • FL / IF: Flawless or Internally Flawless

  • VVS1–VVS2: Very, very slight inclusions (hard to see even under magnification)

  • VS1–VS2: Very slight inclusions (not visible to the naked eye)

  • SI1–SI2: Slight inclusions, typically invisible without magnification

  • I1–I3: Visible inclusions

💡 Tip: SI1 or SI2 diamonds with an excellent cut often look clean to the naked eye and offer exceptional value.

4. Cut

The cut determines how light interacts within the diamond and creates its sparkle.
A rough diamond has no brilliance until it’s cut and polished.
A well-cut diamond with perfect symmetry, proportion, and polish will always appear livelier and brighter than a larger but poorly cut one.
If you can only invest in one quality factor, make it the cut.

✨ Before You Buy

  • Set Your Priorities: Decide what matters most — size, color, clarity, or brilliance.

  • Balance Quality and Budget: A well-cut diamond with SI clarity and G–H color is a smart, beautiful choice.

  • Ask Questions: Understanding your diamond means making an informed, confident purchase.
