Lab Grown Diamond Necklace Price in India 2026

The cost of a lab grown diamond necklace depends on its total diamond weight, individual stone specifications, gold weight and craftsmanship. Here is an indicative price comparison for popular designs.

These are indicative retail estimates for 2026, not guaranteed market prices. Actual quotations vary according to diamond grading, gold weight, design, making charges and applicable taxes.

How Is the Price of a Lab Grown Diamond Necklace Calculated?

A jewellery quotation generally includes four major components:

• Diamond cost

• Gold cost

• Making charges

• Applicable GST

For example, consider a hypothetical 1 carat solitaire pendant made in 18K gold.

This example assumes a gold rate of ₹10,000 per gram for 18K gold and making charges of ₹1,800 per gram. These are illustrative inputs, not verified live market rates.

The calculation shows why comparing only the diamond price is not enough. Gold weight and manufacturing costs also influence what you eventually pay.

How Gold Purity Affects Necklace Pricing

Gold is an important part of the overall necklace cost. Lab grown diamond necklaces are commonly available in 14K and 18K gold.

14K gold generally costs less because it contains a lower proportion of pure gold. It is also a practical choice for jewellery intended for frequent wear. On the other hand, 18K gold offers a higher gold content and is widely preferred for fine diamond jewellery.

When comparing two necklaces, check their actual gold weight rather than choosing based on purity alone.

Understanding Diamond Quality Before Buying

The 4Cs help you evaluate the quality of a lab grown diamond. They include cut, colour, clarity and carat weight.

Cut: Determines how effectively a diamond reflects light. A well-cut diamond can appear brighter and more lively.

Colour: Graded from D to Z, with D representing colourless diamonds. D, E and F grades are popular choices for colourless jewellery.

Clarity: Measures internal inclusions and external blemishes. VVS and VS grades are commonly considered when selecting fine diamond jewellery.

Carat: Measures the weight of a diamond. Remember that total carat weight in a multi-stone necklace is different from the weight of its largest individual diamond.

For additional confidence, check the grading report from a recognised laboratory such as IGI and verify that the certificate details match the diamond being purchased.

Which Lab Grown Diamond Necklace Design Should You Choose?

Different necklace styles serve different purposes. Your choice should depend on how you plan to wear the jewellery.

Solitaire Pendant

A solitaire pendant features one centre diamond and a simple chain. It is suitable for everyday wear, office outfits and minimal jewellery preferences.

Heart Diamond Necklace

Heart-shaped pendants are popular for anniversaries, birthdays and gifting. They can feature a single heart-shaped diamond or several smaller diamonds arranged in a heart design.

Halo Necklace

Halo necklaces feature a centre diamond surrounded by smaller stones. This setting adds detail and creates a larger overall appearance.

Tennis Necklace

A tennis necklace features diamonds arranged continuously along the chain. It offers a more noticeable look and is often selected for parties, celebrations and special occasions.

Lab Grown vs Natural Diamond Necklace: Which Offers Better Value?

Lab grown and natural diamonds have the same fundamental chemical composition, crystal structure and physical properties. The primary difference is their origin.

Natural diamonds form beneath the Earth's surface over millions of years, while lab grown diamonds are produced using CVD or HPHT technology in controlled environments.

Lab grown diamonds generally cost considerably less than comparable natural diamonds with similar specifications. This price difference allows buyers to consider larger diamond sizes and more elaborate designs within their budget.

However, buyers should also understand that lab grown diamonds typically have lower resale value and should not be treated as an investment purchase.

5 Things to Check Before Buying a Lab Grown Diamond Necklace

1. Diamond certification: Check the grading report and verify the diamond's specifications.

2. Gold hallmark: Look for BIS hallmarking to confirm the gold purity.

3. Chain quality: Check the chain length, thickness, clasp and overall construction.

4. Complete price breakup: Ask for separate diamond, gold, making charge and GST details.

5. After-sales policies: Understand the return, exchange, repair and warranty terms before ordering.
