Complete Buying Guide — Carat Sizing, the 4Cs, White vs Yellow Gold, IGI Certification & a Real Lab vs Natural Comparison
Shop IGI Certified Studs →What Does IGI Certified Mean?
IGI — the International Gemological Institute — is the world’s leading independent grading laboratory for lab-grown diamonds. When a diamond is IGI certified, it has been assessed by trained gemologists with no commercial interest in the stone’s value.
The 4Cs — Independently Verified
Every IGI certificate documents cut quality, color grade, clarity grade, and exact carat weight — the four factors that determine a diamond’s appearance and value.
Full Transparency, Zero Guesswork
Without certification, you’re taking the seller’s word on quality. With an IGI certificate, every grade is independently verified and traceable by certificate number on the IGI website.
- G–H color — near-colorless, ideal for both white and yellow gold settings
- VS2–SI1 clarity — eye-clean with no visible inclusions
- Excellent cut — round brilliant, maximum light return
- IGI certificate included with every pair — verifiable online at igi.org

Are Lab Grown Diamonds Real Diamonds?
Yes — unequivocally. Lab-grown diamonds are not simulants. They are not cubic zirconia, moissanite, or glass. They are real diamonds.
| Property | Lab Grown Diamond | Natural Diamond | Cubic Zirconia |
|---|---|---|---|
| Chemical composition | Pure carbon (C) | Pure carbon (C) | Zirconium dioxide |
| Hardness (Mohs) | 10 | 10 | 8–8.5 |
| Refractive index | 2.42 | 2.42 | 2.15–2.18 |
| IGI certification | ✓ Yes | ✓ Yes | ✗ No |
| Detectable difference | Origin only (specialist equipment) | Benchmark | Visually distinct to trained eye |
The only difference between a lab-grown and natural diamond is origin — one formed over billions of years underground, the other grown in weeks via CVD (Chemical Vapor Deposition). Both are graded by the same laboratories using the same standards.

Carat Size Guide — How to Choose
Carat weight is the most visible factor in how your studs look on the ear. Because lab-grown diamonds cost 50–70% less than equivalent natural stones, you can choose a larger carat weight for the same budget.
| Carat (pair total) | Visual Presence | Best For | Lab Grown Advantage |
|---|---|---|---|
| 0.50ct | Subtle, refined | Daily wear, minimalist style | Accessible entry point |
| 1.00ct | Classic, noticeable | Everyday luxury, most popular | Natural equivalent costs 2–3× more |
| 1.50–2.00ct | Bold, brilliant | Elevated daily wear, occasions | Natural equivalent costs 3–4× more |
| 2.50–4.00ct | Statement, commanding | Milestone gifting, special occasions | Natural equivalent rarely accessible |

The 4Cs — What to Prioritize for Studs
For stud earrings, cut is the most important factor — it determines how much light the diamond returns to the eye.
Cut — Excellent Round Brilliant
Cut determines brilliance. An excellent cut round brilliant maximizes light return, fire, and scintillation. Never compromise on cut — a poorly cut diamond looks dull regardless of color or clarity.
DEEVE standard: Excellent cut, round brilliant only.
Color — G–H (Near-Colorless)
D–F is colorless (premium price, minimal visible difference). G–H is near-colorless — the sweet spot where color is undetectable to the naked eye at significantly better value.
DEEVE standard: G–H color.
Clarity — VS2–SI1 (Eye-Clean)
VS2–SI1 means inclusions are not visible to the naked eye — only under 10× magnification. Eye-clean appearance without paying for flawless grades that offer no visible benefit.
DEEVE standard: VS2–SI1 — eye-clean, maximum value.
Carat — Choose Your Presence
Lab-grown diamonds allow you to choose a larger carat weight for the same budget as a smaller natural stone. The 1.00ct lab grown pair above costs less than the 0.50ct natural pair.
DEEVE range: 0.50ct to 4.00ct per pair.
White Gold vs Yellow Gold — Which to Choose
Both are solid 14K gold — never plated, filled, or vermeil. The choice is purely aesthetic.
Maximum Diamond Brilliance
White gold’s rhodium finish creates a cool, bright backdrop that makes the diamond appear to float in pure light. The most popular choice for round brilliant studs.
Best for: Maximizing sparkle · Cool skin tones · Modern, minimalist styling
Warm, Timeless Elegance
Yellow gold adds rich warmth that complements all skin tones and pairs beautifully with other gold pieces. A sophisticated, classic choice that never goes out of style.
Best for: Warm skin tones · Classic styling · Layering with gold jewelry
How to Buy IGI Certified Lab Grown Diamond Studs — Step by Step
Choose Your Carat Weight
Start with how you want the studs to look on the ear. 1.00ct is the most popular everyday choice. Use the carat guide above or our Size Guide for reference.
Select Your Metal
White gold for maximum brilliance. Yellow gold for warmth and classic elegance. Both are solid 14K — the decision is purely about your personal style.
Verify the IGI Certification
Every DEEVE lab-grown stud includes an IGI certificate. You can verify any certificate number at igi.org. Learn more: How to Read Your IGI Certificate.
