Lab Grown Diamond Necklaces: Styles, Price & Buying Guide

Home / Lab Grown Diamond / Necklaces

A lab-grown diamond necklace uses real, laboratory grown diamonds set in a gold or platinum chain or setting. The main styles are pendant necklaces, halo and cluster necklaces, tennis necklaces, chain necklaces, and diamond mangalsutras. To style well, match the necklace length to your neckline, choose between an everyday style or a statement diamond necklace, and review the total diamond weight (CTW) onto the products details. Check out the trending lab grown diamond necklace designs in your budget ranging upto ₹1 lakh.

A necklace sits close to the face, so the way it frames the neck and the neckline matters as much as the diamonds. This guide covers the main styles, how length and neckline work together, the price bands, and the choices that are specific to Indian customers, such as the diamond mangalsutra. If you are mainly looking at a single solitaire on a chain, our pendants guide goes deeper into that style. For general background, see the main lab grown diamond guide.

Necklace styles

Length and neckline

The necklace’s length decides where the diamond sits, and the right length depends on the neckline you wear most often. Below are the standard jewellery lengths that apply to most necklaces, but check the length listed on each product page.

A simple test: if you mostly wear round-neck kurtas or crew-neck tops, a 16 to 18 inch chain will sit visibly above the neckline. With a V-neck, the pendant can sit slightly lower and follow the line of the V. With a high collar, go longer or choose a piece that sits on top of the collar.

Statement or daily wear?

This is the most useful question to ask before you look at prices. A statement necklace, such as a emerald cut and oval double halo, a tennis necklace or a large cluster, is something you wear on occasions and pair with outfits that suit it. A daily wear necklace is lighter, usually a single stone or a simple drop that you can wear every day without thinking about it.

Diamond mangalsutra

For many Indian buyers, the mangalsutra is the necklace that matters most, and lab-grown diamonds have made diamond mangalsutras more accessible. A diamond mangalsutra usually combines black beads with a diamond pendant, in gold. The questions to ask are the same as for any necklace: what is the total diamond weight, what is the metal and purity, and how long is the chain. In addition, think about how often you will wear it. A slim, modern design works for daily wear, while a larger pendant suits occasions. If you prefer something more modern on the wrist, there is also a mangalsutra bracelet collection.

Choosing Necklace by metal and colour

Lucira offers gold necklaces in 14KT and 18KT, in yellow, white, and rose colours. White gold keeps the look cool and lets the diamonds dominate. Yellow and rose gold feel warmer and work with traditional outfits. 18KT has a higher gold content and a richer colour, and 14KT is generally harder and costs less. 

For a necklace, the chain is the part that takes the most strain, so look for the chain thickness and the clasp as well as the diamond. Gold jewellery in India should carry a BIS hallmark with a HUID where hallmarking applies, so check the marking when you receive the piece.

Choosing a lab grown diamond necklace involves finding the right balance between design, diamond quality and budget. Whether you're considering a delicate solitaire pendant, an elegant diamond mangalsutra, or a statement tennis necklace, use Lucira's jewellery EMI calculator to understand your payment options and plan your purchase around your preferred diamond carat weight, gold purity, and necklace style.

Layering and styling of Necklace

• Two necklaces: pair a short chain, around 16 inches, with a longer one, around 20 inches, so each has its own space.
• Mix thin and thick: a fine diamond chain next to a plain gold chain works better than two intricate pieces.
• Keep metals together: layering in the same colour of gold looks cleaner, although mixed metals can work if the pieces are clearly different.
• Match the occasion: a delicate necklace suits daily wear, while a halo or tennis necklace needs a simpler outfit so it can stand out.

How to Care for and Clean a Lab Grown Diamond Necklace

Proper lab grown diamond necklace care helps maintain the brilliance of your diamonds and keeps the gold chain and setting in good condition. Lab grown diamonds have the same physical and chemical properties as natural diamonds, so they require similar cleaning and maintenance. Whether you own a delicate solitaire pendant, an everyday diamond necklace, or a statement tennis necklace, following a few simple jewellery care tips can help preserve its beauty.

How to Clean a Diamond Necklace at Home

You can clean most diamond necklaces at home using a gentle cleaning method:

1. Prepare a mild cleaning solution: Mix a few drops of mild soap with lukewarm water. Avoid harsh chemicals, bleach or abrasive jewellery cleaners.
2. Clean the necklace gently: Use a soft-bristled brush to remove dirt and residue around the diamonds and setting. Take extra care with delicate chains and small stones.
3. Rinse carefully: Rinse the necklace with clean lukewarm water, using a small bowl rather than rinsing directly over an open drain.
4. Dry with a soft cloth: Gently pat the jewellery dry using a clean, lint-free cloth before storing or wearing it.

For delicate or intricate designs, consult a jewellery professional before cleaning.

How to Store a Diamond Necklace Safely

Proper diamond necklace storage helps prevent tangled chains, scratches and damage.

• Fasten the clasp: Secure the necklace clasp before storing to minimise tangling.
• Use a separate jewellery pouch: Store each diamond necklace in a soft-lined jewellery box or individual pouch to prevent contact with other jewellery.
• Keep it away from moisture: Choose a clean, dry storage area away from excessive humidity and direct sunlight.
• Avoid mixing jewellery pieces: Keep diamond necklaces separate from delicate gold chains and softer gemstones to reduce scratching.

Everyday Diamond Necklace Maintenance Tips

To maintain your diamond necklace's shine and durability, follow these simple precautions:

• Avoid direct contact with perfume and cosmetics: Apply perfume, lotions and hairspray before putting on your necklace to minimise product buildup.
• Remove before swimming or exercising: Chlorine, sweat and physical activity can affect metal finishes or place unnecessary stress on delicate chains.
• Check the chain and clasp: Regularly inspect the clasp, links and diamond setting for signs of looseness or wear.
• Clean periodically: Gentle cleaning helps remove oils, dust and residue that can make diamonds appear dull.
• Consider professional inspection: Have the necklace checked by a qualified jeweller if you notice loose stones, damaged prongs or a weakened clasp.

With regular care, your lab grown diamond necklace can retain its beautiful appearance for years.

Lab grown or natural diamond for a necklace?

For a necklace, the gap between lab-grown and natural diamonds mostly shows up in larger designs. A halo, cluster, or tennis necklace uses a lot of stones, and the total price scales with the total weight. Lab-grown diamonds are usually priced lower for similar size and quality, so the same budget can buy a fuller design or a bigger centre stone. For a simple pendant necklace, the difference is smaller in absolute terms, but it still lets you move up a stone size.

What does not change is how you evaluate the piece: the stones, the metal, the chain and the clasp. A necklace is only as good as the part most likely to fail, which is usually the chain or the clasp. Ask about the metal weight and the type of clasp, not only the diamonds. Our main guide covers the stones in more depth.

How can you tell if a diamond necklace is real?

Check the documentation and the markings. A grading report for a larger centre stone, a stated total diamond weight for smaller stones, the hallmark on the gold and a clear written policy are what you should expect. Home tests are unreliable, and handheld testers cannot tell a lab grown diamond from a natural one.

Frequently asked questions

How much is a lab grown diamond necklace in India?

At Lucira, diamond necklaces were listed from roughly ₹34,000 to over ₹1 lakh in October 2026, depending on the number and size of diamonds and the metal. Check the live product page for current pricing.

What necklace length is best?

16 to 18 inches is the most versatile length and sits on the collarbone. Choose a shorter length for open necklines and a longer one for high necklines or layering.

What is the difference between a pendant and a necklace?

A pendant is the hanging ornament, and a necklace is the whole piece including the chain. When a pendant comes on a chain, it is sold as a pendant necklace. Our pendants guide covers solitaire pendants in more detail.

Are diamond mangalsutras available in lab grown diamonds?

Yes. Lucira has diamond mangalsutra collections with lab grown diamonds in gold, including modern and daily wear designs. Check the product page for diamond weight, gold purity and chain length.

Which gold colour suits a diamond necklace?

White gold keeps the look cool and lets the diamond stand out. Yellow and rose gold feel warmer and suit traditional outfits. Choose the colour you wear most often.

Can I wear a diamond necklace every day?

Yes, if you choose a light design with a secure clasp. A single stone pendant necklace is the most practical for daily wear. Remove it for the gym and swimming.

How can I tell if a diamond necklace is real?

Rely on documentation, not on looks. A grading report for larger stones, a stated total diamond weight, the hallmark on the gold and a written return policy are the dependable checks. Simple testers cannot separate lab grown from natural diamonds.
