What to Know When Shopping for 9 Carat Radiant Lab Grown Diamonds

  1. Always compare identical certified diamonds across retailers. Identical certificate numbers can have price differences of $44,943 or more.
  2. Focus on the 4Cs that matter most to you. Color and clarity grades drive price more than cut in many segments, but cut affects sparkle the most.
  3. The median price of $4,420 is a useful benchmark. If you see a deal significantly below this, verify the retailer's reputation and return policy.
  4. Consider eye-clean alternatives. Moving one clarity grade down (e.g., VS2 to SI1) can save 10-15% with no visible difference to the naked eye.
  5. Lab-grown diamonds offer excellent value. Ensure the stone comes with a GIA or IGI certificate confirming it is laboratory-grown.
  6. Check shipping, insurance, and return policies. The lowest sticker price is not always the best deal once you factor in total cost of purchase.
  7. Radiant cuts combine the elegance of emerald shapes with the brilliance of round cuts, offering good value per carat.

Diamond Terminology

Carat
A unit of weight for diamonds equal to 200 milligrams. Larger carat weights are exponentially rarer, which is why prices increase non-linearly with size.
Cut
Refers to how well a diamond's facets interact with light. Cut quality ranges from Ideal to Poor and is the single biggest factor affecting a diamond's brilliance.
Color
Grades a diamond's lack of color on a scale from D (colorless) to Z (light yellow). Grades D-F are considered colorless; G-J are near-colorless and offer good value.
Clarity
Measures the presence of internal inclusions or surface blemishes. Grades range from Flawless (FL) to Included (I3). Most inclusions in VS2 and above are invisible to the naked eye.
