Lab grown diamond necklace offers the same dazzling brilliance as mined diamonds, but with a smaller environmental footprint and no ethical concerns tied to traditional mining. Lab-grown diamonds are created in controlled settings that replicate the natural diamond-growing process, resulting in stones that are chemically, optically, and physically identical to mined diamonds—at a more accessible price point. The global lab grown diamond market size was valued at $22.79 billion in 2023 & is projected to grow from $25.89 billion in 2024 to $74.45 billion by 2032, with necklaces leading the trend as shoppers seek everyday luxury that aligns with their values. Whether you’re drawn to a delicate solitaire pendant for the office or a bold halo design for special occasions, a lab-grown diamond necklace lets you wear sparkle with purpose.
What Makes Lab Grown Diamond Necklace Special?
Lab-grown diamond necklaces stand out from traditional diamond jewelry for their unique blend of ethics, affordability, and beauty. They’re designed for modern consumers who want to look good while doing good—without compromising on style.
Core Traits of Lab-Grown Diamond Necklaces
-
Ethical & Sustainable: Unlike mined diamonds, lab-grown diamonds require no earth excavation, which reduces deforestation, soil erosion, and water pollution. They also avoid the risk of “conflict diamonds” (stones linked to human rights abuses). Most lab-grown diamond brands use renewable energy in production, further lowering their environmental impact.
-
Identical Sparkle: Lab-grown diamonds have the same refractive index, hardness (10 on the Mohs scale), and fire as mined diamonds—meaning they shine just as brightly. Even jewelers can’t tell the difference without specialized equipment.
-
Accessible Luxury: Lab-grown diamonds cost 30–50% less than mined diamonds of the same quality. This makes diamond necklaces affordable for more people—whether you’re buying a gift or treating yourself to a piece of everyday luxury.
-
Versatile Style: Lab-grown diamond necklaces come in endless designs, from minimalist solitaire pendants to intricate halo styles. They pair with everything from casual tees to formal gowns, making them a staple in any jewelry collection.
Popular Styles of Lab Grown Diamond Necklace
Lab-grown diamond necklaces cater to every taste, from understated to eye-catching. Here are the most beloved styles for 2024:
1. Lab-Grown Diamond Solitaire Pendant (Everyday Elegance)
The most versatile style—ideal for minimalists or anyone new to diamond jewelry:
-
Design: A single lab-grown diamond (0.25–1 carat) set in a simple metal setting (14k gold, white gold, or sterling silver) on a delicate chain (16–18 inches). The diamond is usually round or princess-cut, with a prong or bezel setting to highlight its sparkle. Prong settings let more light into the diamond for maximum shine; bezel settings offer extra protection (great for active lifestyles).
-
Best For: Office wear, casual outings, or everyday use. A 0.5-carat round lab-grown diamond solitaire in white gold pairs with a button-down shirt and jeans; a princess-cut solitaire in rose gold complements a sweater and leggings.
-
Why It Works: It’s subtle enough for professional settings but sparkly enough to feel special. The solitaire design lets the diamond be the star, making it a timeless piece that never goes out of style.
2. Lab-Grown Diamond Halo Necklace (Glamorous Sparkle)
For anyone who loves extra shine—perfect for special occasions:
-
Design: A central lab-grown diamond (0.5–1.5 carats) surrounded by a “halo” of smaller lab-grown diamonds (0.01–0.05 carats each) on a metal chain (18–20 inches). The setting is often 14k or 18k gold, with the halo adding depth and making the central diamond appear larger. Popular variations include oval or cushion-cut central diamonds for a modern twist.
-
Best For: Date nights, weddings, or holiday parties. A round lab-grown diamond halo necklace in yellow gold pairs with a little black dress; an oval halo in white gold complements a formal gown.
-
Why It Works: The halo of small diamonds amplifies the sparkle, creating a glamorous look that turns heads. It’s a step up from a solitaire but still versatile enough to wear beyond special events.
3. Lab-Grown Diamond Layered Necklace Set (Trendy & Playful)
For lovers of layered jewelry—ideal for casual or boho-inspired styles:
-
Design: A set of 2–3 thin necklaces with small lab-grown diamonds (0.1–0.25 carats each). Each necklace has a different length (14, 16, and 18 inches) and design: one with a tiny solitaire pendant, another with a diamond-encrusted bar, and a third with a small diamond drop. The metals are coordinated (e.g., all rose gold or a mix of white and yellow gold).
-
Best For: Weekend brunches, concerts, or everyday wear. Wear the set together with a graphic tee and high-waisted shorts, or mix and match with other necklaces in your collection.
-
Why It Works: Layered necklaces are on-trend, and the small lab-grown diamonds add subtle sparkle without feeling overdone. The set lets you experiment with styling, making it a fun addition to any jewelry box.
4. Lab-Grown Diamond Bar Necklace (Modern Minimalism)
A sleek, contemporary style—great for those who prefer clean lines:
-
Design: A thin metal bar (1–2 inches long) in 14k gold or white gold, set with 3–5 small lab-grown diamonds (0.05–0.1 carats each) in a channel or prong setting. The bar hangs horizontally on a delicate chain (16–18 inches), creating a minimalist, modern look.
-
Best For: Office wear, casual outings, or as a gift. A white gold lab-grown diamond bar necklace pairs with a blazer and tailored pants; a yellow gold bar necklace works with a sundress and sandals.
-
Why It Works: It’s understated yet stylish, with the diamonds adding just enough sparkle to elevate everyday outfits. The horizontal bar flatters the collarbone, making it a flattering choice for all necklines.
How to Choose the Perfect Lab Grown Diamond Necklace
Choosing a lab-grown diamond necklace is about balancing quality, style, budget, and ethics. Follow these steps to find your ideal piece:
Step 1: Understand Lab-Grown Diamond Quality (The 4 Cs)
Like mined diamonds, lab-grown diamonds are graded by the 4 Cs—Cut, Color, Clarity, and Carat Weight. These factors determine the diamond’s sparkle and value:
-
Cut: The most important factor for sparkle. A well-cut diamond reflects light evenly, creating maximum fire and brilliance. Look for “Excellent” or “Very Good” cut grades (avoid “Fair” or “Poor,” which dull the diamond’s shine).
-
Color: Lab-grown diamonds range from D (colorless) to Z (light yellow/brown). For necklaces, D–J colors are ideal—they appear colorless to the naked eye. If you’re on a budget, K–M colors offer good value (subtle warmth that’s hard to notice without close inspection).
-
Clarity: Measures the number of inclusions (tiny flaws) in the diamond. For small diamonds (under 0.5 carats), SI1–SI2 clarity is perfect—no inclusions are visible to the naked eye. For larger diamonds (1+ carats), VS2–VVS2 clarity ensures a clean, sparkling look.
-
Carat Weight: The diamond’s size. Choose based on your style and budget: 0.25–0.5 carats for subtle everyday wear, 0.5–1 carat for a noticeable sparkle, and 1+ carats for a bold statement.
Step 2: Choose the Right Metal & Chain Length
The metal and chain length affect the necklace’s look and durability:
-
Metals:
-
White Gold: Sleek and modern—complements colorless or cool-toned diamonds. It’s coated with rhodium for a bright finish (replate every 1–2 years to maintain shine).
-
Yellow Gold: Classic and warm—pairs beautifully with diamonds that have subtle warmth (K–M colors). It’s durable and doesn’t require replating.
-
Rose Gold: Romantic and trendy—adds a soft pink hue that flatters all skin tones. It’s a great choice for solitaire or halo necklaces.
-
Sterling Silver: Affordable and versatile—ideal for budget-friendly pieces. Look for silver plated with rhodium to prevent tarnishing.
-
Chain Lengths:
-
14 Inches (Choker): Sits tightly around the neck—great for bar necklaces or small pendants with high-necked tops.
-
16 Inches (Princess Length): The most popular length—sits at the base of the neck. Perfect for solitaire pendants or everyday wear.
-
18 Inches (Matinee Length): Falls just below the collarbone—ideal for halo necklaces or layering with shorter chains.
-
20–24 Inches (Opera Length): Longer lengths that can be worn doubled or as a single strand—great for formal events or bold pendants.
Step 3: Match to Your Lifestyle & Occasion
-
Active Lifestyles (Gym, Hiking, Manual Work): Choose a bezel-set solitaire pendant or bar necklace (prong settings can catch on gear). Opt for 14k gold or sterling silver (durable metals that resist scratches).
-
Office Wear: A small solitaire pendant (0.25–0.5 carats) or bar necklace in white or yellow gold. It’s subtle enough for professional settings but adds polish to your look.
-
Casual Weekends: A layered necklace set or a small halo pendant. Pair with jeans, tees, or sundresses for a relaxed, trendy vibe.
-
Formal Events: A larger halo necklace (1+ carat central diamond) or a diamond-encrusted drop necklace. Choose 18k gold for extra luxury.
Step 4: Set a Realistic Budget
Lab-grown diamond necklaces range in price from \(200 to \)5,000+, depending on the diamond’s quality, metal, and design:
-
Budget Under $500: Small solitaire pendants (0.25–0.3 carats, SI1 clarity, J–M color) in sterling silver or 10k gold.
-
Budget \(500–\)1,500: Medium solitaire or bar necklaces (0.5–0.75 carats, VS2 clarity, G–J color) in 14k gold.
-
Budget \(1,500–\)3,000: Halo necklaces (0.75–1 carat central diamond, VVS2 clarity, D–G color) in 14k gold.
-
Budget Over $3,000: Large halo or custom necklaces (1+ carat central diamond, VVS1 clarity, D–F color) in 18k gold with additional diamond accents.
How to Style & Care for a Lab Grown Diamond Necklace
A lab-grown diamond necklace is a versatile piece—here’s how to make the most of it:
Styling Tips
-
Everyday Wear: Pair a solitaire or bar necklace with minimal other jewelry. A white gold solitaire looks great with small silver earrings; a rose gold bar necklace pairs with a simple gold ring. Avoid stacking bulky bracelets (they can distract from the necklace’s sparkle).
-
Layered Looks: Mix a lab-grown diamond necklace with other delicate chains. Try a 16-inch solitaire pendant with a 14-inch choker (without diamonds) and an 18-inch bar necklace. Stick to the same metal family (e.g., all gold tones) for a cohesive look.
-
Formal Events: Let a halo necklace be the focal point. Pair it with diamond stud earrings (matching lab-grown diamonds) and a simple bracelet. Avoid a statement necklace with a high-necked gown—opt for a longer opera-length necklace instead.
-
Neckline Pairings:
-
V-Necks: A solitaire or drop necklace that follows the V-shape—elongates the neck and draws attention to the necklace.
-
Round Necks/Crewnecks: A princess-length solitaire or bar necklace—sits at the collarbone and adds sparkle without clashing.
-
High Necks: A choker-length necklace or a long opera-length necklace (worn doubled)—avoids competing with the neckline.
Care Tips
Lab-grown diamonds are just as durable as mined diamonds, but proper care will keep your necklace looking shiny for years:
-
Daily Care:
-
Remove the necklace before swimming (chlorine can damage metal), showering (soap builds up on diamonds), or applying lotion/perfume (chemicals can dull sparkle).
-
Wipe the necklace with a soft microfiber cloth after wearing to remove oil or dirt.
-
Deep Cleaning:
-
Clean the necklace every 2–3 months with warm, soapy water (mild dish soap) and a soft-bristled toothbrush. Gently scrub the diamond and setting to remove buildup—pay extra attention to the back of the diamond (where dirt collects).
-
Rinse thoroughly and pat dry with a cloth. For extra sparkle, use a jewelry cleaner designed for diamonds (avoid ammonia-based cleaners for gold metals).
-
Storage:
-
Store the necklace in a soft jewelry pouch or a divided jewelry box (separate from other jewelry to prevent scratches).
-
Hang necklaces on a jewelry tree to keep chains from tangling—this also prevents the diamond from getting scratched by other pieces.
-
Have the necklace inspected by a jeweler once a year—they’ll check the setting for loose diamonds and polish the metal to restore shine.
Frequently Asked Questions About Lab Grown Diamond Necklace
Q1: Are lab-grown diamonds “real” diamonds?
A: Yes! Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds.

Q2: Will a lab-grown diamond necklace hold its value?
A: Lab-grown diamond necklaces hold their value well for everyday wear, though they may not appreciate like rare mined diamonds. However, their lower initial cost and ethical appeal make them a practical choice for most consumers. Unlike fast-fashion jewelry, high-quality lab-grown diamond necklaces (in 14k+ gold) will last for decades.
Q3: Can people tell the difference between lab-grown and mined diamond necklaces?
A: No—even experienced jewelers can’t tell the difference without specialized equipment (like a UV light or a gemological microscope). Lab-grown diamonds have the same sparkle, hardness, and appearance as mined diamonds.

A: Absolutely! They’re thoughtful, versatile, and align with many people’s ethical values. A solitaire pendant makes a great birthday or anniversary gift; a layered set is perfect for a friend who loves trendy jewelry. Add a personal touch by choosing a metal that matches their existing jewelry.
Q5: Do lab-grown diamond necklaces come with certificates?
A: Yes—reputable brands provide a certificate from a third-party gemological lab (like the GIA, IGI, or AGS) for each lab-grown diamond. The certificate includes details about the 4 Cs, origin (lab-grown), and authenticity. Always ask for a certificate to ensure you’re getting a high-quality diamond.
