IGI Certified Lab Grown Diamond Stud Earrings — Complete Buying Guide

An IGI-certified lab-grown diamond stud earring is a single round brilliant laboratory-grown diamond set in solid gold on a post, accompanied by an International Gemological Institute report stating its cut, colour, clarity and carat weight. Stud carat weights are quoted as cttw — the combined weight of the pair, not of one stone.

Quick Answer

IGI-certified lab-grown diamond stud earrings are real diamonds, independently graded by the International Gemological Institute and set in solid 14K gold. DEEVE's standard across the range is G colour, VS2 clarity and Excellent round brilliant cut, in weights from 0.50 to 4.00 cttw. Because lab-grown pricing sits well below natural, the same budget reaches roughly double the carat weight. Cut matters most on a stud: with nothing beside it on the ear, light return is the only thing the eye reads.

Quick Answer: IGI certified lab grown diamond stud earrings are real diamonds — chemically and physically identical to mined diamonds — independently graded by the International Gemological Institute for cut, color, clarity, and carat. Set in solid 14K gold with push-back closures, they offer exceptional brilliance at approximately 70% less than equivalent natural stones. Every DEEVE lab grown pair includes an IGI certificate and lifetime warranty.

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.

What IGI Grades

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.

Why It Matters

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.

The DEEVE IGI Standard:
  • G color — near-colorless, ideal for both white and yellow gold settings
  • VS2 clarity — eye-clean with no visible inclusions
  • Excellent cut — round brilliant, maximum light return
  • IGI certificate included with every lab grown 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.

Lab Grown vs Natural Diamond Studs — Real Product Comparison

Here’s a side-by-side look at two actual DEEVE products — one lab grown, one natural — so you can see exactly what the difference looks like in practice.

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.

#1 Priority

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.

#2 Priority

Color — G (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 color, at every carat weight in the range.

#3 Priority

Clarity — VS2 (Eye-Clean)

VS2 and SI1 both mean 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 — eye-clean, maximum value.

#4 Priority

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.

14K WHITE GOLD

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

14K YELLOW GOLD

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

1

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.

2

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.

3

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.

4

Confirm Solid Gold Construction

Ensure the earrings are solid 14K gold — not gold-plated, gold-filled, or vermeil. DEEVE uses solid 14K gold exclusively. Never plated. Never filled.

5

Check the Backing Type

A push back is the standard closure for fine diamond studs — quick to put on, comfortable in daily wear, and secure on a four-prong basket. Every DEEVE diamond stud uses a push back, and our in-house workshop replaces a back or tightens a prong under the lifetime warranty.

6

Frequently Asked Questions

What does IGI certified mean for lab grown diamond studs?

IGI (International Gemological Institute) independently grades each diamond for cut, color, clarity, and carat weight. Every pair includes an IGI certificate — verifiable at igi.org.

Are lab grown diamonds real diamonds?

Yes. Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds — same hardness (10 Mohs), same brilliance, same fire. They are not simulants like cubic zirconia or moissanite.

How much cheaper are lab grown diamond studs vs natural?

Lab-grown diamonds typically cost approximately 70% less than equivalent natural diamonds. As shown in the comparison above, a 1.00ct IGI certified lab grown pair costs $880 vs $1,207 for a 0.50ct natural pair — twice the carat at a lower price.

What carat size should I choose?

0.50ct is refined and subtle. 1.00ct is the classic choice. 1.50–2.00ct is bold and brilliant. 2.50–4.00ct delivers maximum presence. See the Size Guide for visual reference.

White gold or yellow gold for diamond studs?

White gold maximizes diamond brilliance with a cool, bright rhodium finish. Yellow gold adds warm, classic elegance. Both are solid 14K — the choice is purely aesthetic.

What backing do DEEVE diamond studs use?

A push back on a classic four-prong basket setting — the standard for fine stud earrings, comfortable for daily wear and easy to put on. Prong checks and back replacement are handled by our in-house workshop under the lifetime warranty.

Do DEEVE lab grown diamond studs come with a warranty?

Yes. Every pair includes DEEVE’s lifetime warranty. Full warranty details here.

What to remember

  • Carat weight on studs is quoted as cttw — the pair combined. A 1.00 cttw pair is two half-carat stones, not two one-carat stones.
  • Cut outranks everything on a stud. There is no setting, no side stone and no context on an ear — only how much light the diamond sends back.
  • G–H colour is the working sweet spot: indistinguishable from colourless once on the ear, at a materially lower price than D–F.
  • VS2–SI1 is eye-clean. Paying up to VVS buys a grade nobody will ever see without a loupe.
  • White gold reads cooler and makes the stone appear to float; yellow gold warms it. Both are solid 14K — the choice is aesthetic, not structural.
  • Check the backing. A push back is standard and secure for daily wear; a screw back adds a second mechanical step for a stone you would rather not lose.

How to Choose Lab-Grown Diamond Studs

Six checks, in order

  1. Read the weight as cttw and halve it to picture the single stone on the ear
  2. Insist on Excellent cut, round brilliant — it is the only grade that changes what you see across a room
  3. Choose G–H colour unless the setting is yellow gold, where J still reads clean
  4. Set clarity at VS2–SI1 and confirm eye-clean rather than paying up the scale
  5. Match the metal to the rest of what you wear daily, not to the diamond
  6. Confirm the IGI report number and check it at igi.org before purchase

From the bench

A 1.00 cttw lab-grown pair typically sits below a 0.50 cttw natural pair in price while carrying twice the weight

Studs are the piece most often worn every day and slept in — the backing is worth more attention than the last clarity grade

If you are buying a first pair as a gift, 1.00 cttw is the weight that reads as considered without needing an occasion

With a ring, the setting does half the work. With a stud, there is nowhere to hide — the stone is alone on the ear and the only thing anyone registers is how it moves in light. That is why I will trade a colour grade for a cut grade on studs every single time, and I have never had a client come back and tell me it was the wrong trade.

FAQ

Questions, answered.

Which of the 4Cs matters most on a stud earring?
Cut. On a ring the setting does half the work, but a stud sits alone on the ear with no side stones and no context, so light return is the only thing the eye reads. An excellent-cut round brilliant at a modest weight will out-perform a larger stone cut poorly.
How do I check that a stud's IGI certificate is genuine?
Enter the report number at igi.org/Verify-Your-Report and confirm the displayed grades match the paper certificate. The same number is laser-inscribed on the diamond's girdle, readable under magnification — the online check plus the inscription together confirm the certificate belongs to that stone.
What is the DEEVE standard for IGI certified studs?
DEEVE IGI certified lab grown diamond studs are G colour, VS2 clarity, excellent cut round brilliant, set in solid 14K white or yellow gold on a classic four-prong basket with push-back closures. Every pair includes an IGI certificate and a lifetime warranty.
