Lab grown diamond earrings are real diamonds — pure crystallized carbon with the same hardness, chemistry and optical properties as diamonds mined from the earth. The difference is origin: they are grown in a controlled environment instead of extracted from the ground. That's why the GIA and IGI grade them using the same 4Cs (cut, color, clarity and carat) applied to natural stones.
This guide is written for shoppers choosing their first or next pair. It covers the sizes we actually make (with millimeter guides), real price ranges from our own catalog, which back type to pick, how to check authenticity, and how to keep your earrings sparkling.
Quick Answer : What Should You Buy?
- First pair / everyday wear: 0.60–1.00 ctw round studs in 14K gold.
- Gift that looks noticeably bigger: 1.40–2.00 ctw, or a halo design.
- Active lifestyle or kids-proof security: screw back earrings.
- Something different: oval, pear, emerald, Asscher or cushion cut studs.

What Size Diamond Studs Should You Choose?
Earring sizes are listed in total carat weight (ctw) — the combined weight of both stones. A 1.00 ctw pair means two 0.50 ct diamonds, one per ear. The table below uses the exact sizes available in our collection. Millimeter widths are approximate for well-cut round diamonds; fancy shapes vary.
| Total Carat Weight | Each Earring | Approx. Round Diameter | Look on the Ear | Best For |
|---|---|---|---|---|
| 0.60 ctw | 0.30 ct | ~4.3 mm | Delicate, refined | Daily wear, second piercings, minimalists |
| 0.80 ctw | 0.40 ct | ~4.8 mm | Subtle but visible | Everyday office-to-evening |
| 1.00 ctw | 0.50 ct | ~5.2 mm | Classic stud | First diamond pair, gifting |
| 1.40 ctw | 0.70 ct | ~5.7 mm | Noticeable sparkle | Anniversaries, milestone gifts |
| 2.00 ctw | 1.00 ct | ~6.5 mm | Bold statement | Special occasions, those who want presence |
| 3.00 ctw | 1.50 ct | ~7.4 mm | Maximum impact | Formal events, statement jewelry |
Sizing tip: diamonds look smaller on the ear than in the box, because they're viewed from a distance and partly framed by hair. If you're torn between two sizes, the larger one usually feels right once worn. Most shoppers land between 0.80 and 1.40 ctw for everyday pairs.
How Much Do Lab Grown Diamond Earrings Cost?
Price depends mostly on carat weight, then cut, color, clarity, shape and metal. Here's what pairs in our own catalog cost at the time of writing (sale prices, 10K–14K gold starting options):
| Style | Example | Starting Price |
|---|---|---|
| Round studs, 0.60 ctw | Four-prong screw back studs | from ~$390 |
| Fancy-shape studs, 0.60 ctw | Pear, cushion, emerald, princess, Asscher, oval | ~$405–$450 |
| Round studs, 1.10 ctw | 1.10 TCW screw back earrings | from ~$550 |
| Diamond hoops | 14K round cut diamond hoops | from ~$668 |
| Halo studs, 1.65 ctw | Round halo screw back earrings | from ~$1,088 |
Prices change with metal choice, carat size and promotions — the product page always shows the current price.
Compared with mined diamonds of the same size and grade, lab grown diamonds cost a fraction of the price. That gap is the main reason shoppers can choose a larger or higher-grade pair for the same budget.
What Drives the Price?
- Carat weight has the biggest impact — price rises faster than size.
- Cut decides how much light the stone returns. A poorly cut diamond looks dull no matter its other grades.
- Color runs from D (colorless) to Z (visible yellow tint).
- Clarity measures internal inclusions. Our earrings use VS2 clarity or better with Excellent cut grades.
- Metal: platinum costs more than 18K gold, which costs more than 14K and 10K.
Value tip: for earrings, prioritize cut over color. Earrings are seen from a distance and not face-up like a ring, so a G–H color stone with an excellent cut looks bright and white while costing less than D–F.
Screw Back vs Push Back: Which Earring Back Is Better?
| Feature | Screw Back | Push Back (Friction) |
|---|---|---|
| Security | Highest — threaded post locks the back in place | Good, but can loosen over time |
| Ease of use | Takes a few seconds to twist on and off | Fastest on and off |
| Best for | Larger stones, daily wear, active lifestyles, sleeping in earrings | Smaller studs, occasional wear |
For anything 1.00 ctw and up, we recommend screw backs — losing a single stone costs far more than the minor inconvenience. Shop our lab grown screw back earrings.
Popular Styles of Lab Grown Diamond Earrings
Classic studs — a single diamond per ear in a four-prong or three-prong setting. The most versatile style, from office to evening. See lab grown diamond stud earrings.
Halo studs — a center stone framed by smaller diamonds, which makes the overall look bigger and brighter for the price.
Diamond hoops — diamonds set along the band, from slim everyday hoops to bolder statement sizes.
Fancy-shape studs — oval, pear, emerald, Asscher, cushion and princess cuts each give a different personality. Emerald and Asscher cuts have a sleek "hall of mirrors" look (see our Asscher vs emerald cut guide), while cushion cuts read softer and romantic (what is a cushion cut?).
Mixed-shape designs — pieces such as our 14K pear and marquise diamond earrings combine shapes for a more fashion-forward look.
Lab Grown Diamond vs Natural Diamond vs Moissanite vs Cubic Zirconia
These four stones often get grouped together, but they are different materials with different strengths.
| Feature | Lab Grown Diamond | Natural Diamond | Moissanite | Cubic Zirconia |
|---|---|---|---|---|
| Material | Carbon | Carbon | Silicon carbide | Zirconium dioxide |
| Is it a diamond? | Yes | Yes | No — its own gemstone | No — a diamond imitation |
| Hardness (Mohs) | 10 | 10 | 9.25 | 8–8.5 |
| Sparkle | White brilliance with balanced fire | Same as lab grown | Stronger rainbow fire | Bright at first; can look cloudy with wear |
| Graded by IGI/GIA as a diamond | Yes | Yes | No | No |
| Durability for daily wear | Excellent | Excellent | Excellent | Fair — scratches over time |
| Relative price | Mid | Highest | Lower | Lowest |
Choose lab grown diamond if you want a real diamond with a grading report at a far lower price than mined.
Choose moissanite if you love extra fire and want the best sparkle-per-dollar in a near-diamond-hard stone. It's an excellent everyday choice — browse our moissanite earrings, including moissanite studs and moissanite hoops.

How to Tell If Diamond Earrings Are Real
1. Ask for a grading report. IGI and GIA are the most widely recognized labs. A report confirms the 4Cs and states whether the stone is natural or laboratory-grown. Many certified lab grown diamonds also carry a microscopic laser inscription on the girdle matching the report number — a disclosure tool, not a way to test the stone yourself.
2. Check the metal stamp. Look for 10K, 14K, 18K or PT950 on the post or back. A missing stamp is worth questioning.
3. Use the right tester. Basic thermal testers can't separate diamond from moissanite. A multi-tester that also measures electrical conductivity is more reliable.
4. Know the warning signs of a fake:
- Air bubbles inside the stone (typical of glass)
- Scratches or cloudy, worn facet edges (typical of CZ)
- Loose, rough or unstamped settings
- No documentation or vague product descriptions
Natural or lab grown? Neither the naked eye nor a standard loupe can tell them apart, and ordinary diamond testers say "diamond" for both. Only advanced gemological lab equipment, such as spectroscopy, can confirm origin. That's why the grading report matters.
For full peace of mind, have any purchase appraised by an independent gemologist with GIA or AGS credentials.
How to Clean Diamond Earrings at Home
Skin oils, lotion, hairspray and dust coat a diamond's facets and dull its sparkle. Cleaning restores it in minutes.
You'll need: warm water, a few drops of mild dish soap, a soft toothbrush and a lint-free cloth.
- Mix warm water with a little dish soap in a small bowl.
- Soak the earrings for 15–20 minutes.
- Gently brush behind the stone and around the prongs, where most buildup collects.
- Rinse under clean running water. Close the sink drain first.
- Pat dry with a lint-free cloth and let them air dry fully before storing.
Avoid bleach, chlorine, toothpaste and abrasive cleaners. Skip ultrasonic cleaners for pavé or halo settings unless a jeweler confirms they're safe. Clean everyday pairs every two to four weeks, and have prongs and screw-back threads checked once a year. More tips on our jewelry care page.
What to Look for When Buying Lab Grown Diamond Earrings
- Grading details: clear 4Cs information and, for larger stones, an IGI or GIA report.
- Matched pair: both stones should be closely matched in size, color and cut so they look identical on the ear.
- Solid gold or platinum: 10K, 14K, 18K gold or platinum, not plated base metal.
- Secure backs: screw backs for larger or everyday pairs.
- Return policy: JBR Jeweler offers a 30-day return policy, giving you time for an independent appraisal.
- Real customer photos: check product-page reviews for photos of the actual piece.

Frequently Asked Questions
Are lab grown diamonds real diamonds?
Yes. They have the same crystal structure, hardness (10 on the Mohs scale) and optical properties as mined diamonds. The GIA and IGI grade them on the same 4Cs scale used for natural diamonds.
What carat size is best for everyday diamond studs?
Between 0.80 and 1.40 ctw (0.40–0.70 ct per ear) suits most people for daily wear — visible sparkle without feeling oversized. Choose 0.60 ctw for a delicate look or 2.00 ctw and up for a statement.
Do lab grown diamonds hold their value?
Lab grown diamonds have limited resale value, and natural diamonds generally resell better. If you're buying for beauty and everyday wear rather than investment, lab grown diamonds give you a larger, higher-quality stone for your budget.
Can a jeweler tell the difference between lab grown and natural?
Not by eye or with a loupe. Standard diamond testers identify both as diamond. Confirming origin requires advanced lab equipment, which is why grading reports state whether a stone is lab grown.
Is moissanite the same as a lab grown diamond?
No. Moissanite is silicon carbide, a separate gemstone with more rainbow fire and a hardness of 9.25. Lab grown diamond is carbon, identical to mined diamond. Both are durable, beautiful choices for everyday earrings.
Are screw back earrings worth it?
For stones 0.50 ct per ear and larger, yes. Screw backs are the most secure everyday option and greatly reduce the risk of losing an earring.
