What to Know When Shopping for 4.3 Carat Oval Lab Grown Diamonds
- Always compare identical certified diamonds across retailers. Identical certificate numbers can have price differences of $51,317 or more.
- 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.
- The median price of $4,755 is a useful benchmark. If you see a deal significantly below this, verify the retailer's reputation and return policy.
- 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.
- Lab-grown diamonds offer excellent value. Ensure the stone comes with a GIA or IGI certificate confirming it is laboratory-grown.
- Check shipping, insurance, and return policies. The lowest sticker price is not always the best deal once you factor in total cost of purchase.
- Oval diamonds can appear larger than rounds of the same carat weight due to their elongated face-up area. Watch for the bow-tie effect in lower-quality cuts.

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.
