Lab-Grown Polki Jewellery: Is It Real, Is It Worth It, and How Much Does It Cost? (2026 Bridal Guide)

Quick note before we start:

This blog gives details about polki jewellery, lab-grown polki, whether it is a real diamond or not, how much it costs compared to natural polki, metal options, the significance of certification, and places to find it in Mumbai. Towards the end of the blog, some FAQs answer some of your questions right away.

What Even Is Polki?

So, polki is basically a diamond in its raw form. Not cut into a round or princess shape as you see in most rings. Just the rough diamond, polished a little on the surface, and set into gold. That's it. This is why it looks more milky and soft compared to a regular cut diamond that throws all that sharp brightness.

It's been around in India for centuries; it goes back to Mughal times, actually. Most heavy bridal sets from Rajasthan or Gujarat weddings—the big chunky necklaces you see—are usually polki. It's not something that just came into fashion recently.

And Lab-Grown Polki?

This is where it gets a bit newer. Instead of digging the rough diamond out of the ground, a lab grows it. There are two ways they do this: HPHT and CVD; both are just fancy names for recreating the same heat and pressure that makes a diamond form naturally, except it happens inside a machine over a few weeks instead of underground over millions of years.

Once that rough crystal is grown, it gets sliced and shaped the same way a real mined rough stone would be. So visually, there's no difference. Brands in Surat and Mumbai have been pushing this a lot lately because polki sets use a lot of carat weight, and mined rough diamonds at that quantity get expensive really fast.

Is it a real diamond, though?

Yes, it is. This gets people confused a lot, so we will just say it straight out. Lab-grown diamonds are composed of the same carbon and have the same hardness and everything else that makes a diamond what it is. Put it under a diamond tester; it will come back as a diamond, as, chemically speaking, it is a diamond. 

The only thing different is where it was made.

Actually, this got a bit more official too. Early this year, the Bureau of Indian Standards brought in a proper rule (IS 19469:2025) that legally defines what counts as a natural diamond versus a lab-grown one, so there's now an actual standard for jewellers to follow instead of just marketing language. That's a good thing for buyers, honestly—less room for anyone to be vague about it.

One thing, though: don't confuse this with moissanite or cubic zirconia. Those are completely different materials and not diamonds at all, lab-grown or otherwise.

Natural Polki vs Lab-Grown Polki, Side by Side:

So What Does It Cost?

Currently, a 1-carat certified natural diamond is priced from 1.5 lakh to 4 lakh rupees. A lab-grown diamond of the same specifications would range from 25,000 to 80,000 rupees.

And since polki jewellery uses a lot of carats in one piece, this gap becomes pretty huge by the time you're looking at a full set.

Just to give you an idea, and this is a made-up example, not a real quote from anywhere. Say you want a bridal choker with around 15 carats of polki stone on it. Naturally, that could cross 15 to 20 lakh just for the stones before you even add the goldwork. In lab-grown, the same visual weight could come to maybe 4 to 7 lakh. That's not a small difference. That's enough to also fund the reception outfit, honestly.

Gold-making charges come on top of all this, doesn't matter which diamond you go with.

What Metals Does It Come In?

Gold is still the go-to, especially 22K because that warm yellow tone is what most people picture with polki. But it's not the only choice now. A lot of jewellers offer it across multiple metals, so 18K and 14K for something lighter and more everyday; silver for smaller pieces you'd wear casually; and rose gold is picking up too if you want something that doesn't look too traditional.

Platinum is rare for polki specifically. The kundan setting technique that polki uses works better with gold because gold is softer to shape. However, if you're dead set on platinum, a good custom jeweller will be able to help you with that.

Why Does Certification Actually Matter?

Whether you choose natural diamonds or man-made ones, do not forget to ask for the certificate. It is important to look at GIA or IGI; these are the proper labs that will tell you the cut, clarity, and carat, and also whether it is natural or man-made. Sometimes there may be an issue with polki since it requires more care when grading, as its uncut look is somewhat tricky for machines.

Also check that the gold is BIS hallmarked. That's the government mark for gold purity in India, and there's really no reason to buy jewellery without it these days; hallmarking centres are everywhere now.

Where To Actually Go Looking In Mumbai?

If you're in Mumbai and want to see these pieces in person before deciding anything, it helps to go to someone who's actually been in the trade a long time, not just a shop that opened last year. Classy Cut, in Ghatkopar, Mumbai, India, comes from a family with over 100+ years of legacy in the diamond business, and we deal in both natural and lab-grown diamonds depending on what you're after.

Everything is certified through labs like GIA and IGI, and the gold is BIS hallmarked, so you're not just taking someone's word for it; it's all on paper. We also do custom pieces, so if you already know the design you want, you can bring a reference and work with your own budget and metal choice instead of picking from whatever's already made. For people comparing shops around the city, Classy Cut tends to come up for having some of the best diamond prices on certified pieces, mostly because a Ghatkopar-based business that's been running this long doesn't carry the same overhead costs as a newer showroom trying to build a name from scratch.

Looking After Your Polki Once You Buy It

Buying it is one part; keeping it nice is another. Polki jewellery, whether natural or lab-grown, is set using something called a lac base; it's basically a natural resin that holds the stones inside the kundan setting. So the care is not really the same as looking after a regular gold chain or a plain diamond ring.

Keep It Away From Water And Perfume

This is the big one, honestly. Never wash your hands or shower while wearing polki, and don't try to soak it clean either. Water eventually makes the lac base weak, and stones begin to fall or even fall out of the jewel entirely. Same goes for perfumes, hairsprays, and lotions – apply all of that to your skin first and only then put on jewellery. If the need to clean arises, just use a dry soft fabric, and this should be more than enough.

Store It Right

Do not just store them together with other items of jewellery. Keep each one separately in a soft pouch without exposure to sun rays and away from moist spots in the wardrobe. Just cotton or velvet pouches will do; the main thing is protection from moisture.

Get It Checked Once A Year

Every year, or once in 12 to 18 months, have it checked by your jeweller and get the setting re-tightened. Loose stones happen slowly, without you realising, particularly if you wear the piece a lot, and fixing it then is much less expensive than replacing a loose stone later.

Is It Actually Worth Buying?

Honestly, if you're getting polki mainly for the wedding day and maybe a few functions after, go lab-grown. Same look, same certification, and you save a big chunk of money that can go elsewhere in the wedding budget. Nobody standing at the mandap is checking where the carbon came from.

Where 'natural' still makes more sense is if this piece is meant to stay in the family for years, something your daughter or daughter-in-law might wear one day. Natural stones still hold resale value better in India; that part hasn't really changed yet, even with all the lab-grown growth happening in the market. So it really depends on whether you're buying this for right now or for later.

To Wrap This Up

Polki isn't going anywhere; it's too tied into how Indian weddings work. What's changed is that now you have a real, certified option in lab-grown that costs a lot less than natural but looks exactly the same. Pick natural if resale and passing it down matter to you. Pick lab-grown if you just want the look for less money. Either way, don't skip the certificate – a GIA or IGI on the diamond or BIS hallmarked on the gold. This applies no matter where you're buying it: whether in Ghatkopar, elsewhere in Mumbai, India, or elsewhere.

FAQs

Q1. Is lab-grown polki any different in appearance to natural?

A1. No, it looks the same, in the same raw, uncut form, with the same lustre; you can't tell the difference by sight alone.

Q2. Will it show up as fake on a diamond tester?

A2. No. It's a real diamond chemically, so it reads the same as natural on a regular tester.

Q3. Is it very affordable due to inferior quality?

A3. No, it'svery affordable due to the lower cost of producing it in a lab rather than extracting it from the earth. The quality is the same.

Q4. Do they use 22K or other metals for lab-grown polki?

A4. Lab-grown polki jewellery is available in 14K, 18K, 22K, and even silver from most jewellers.

Q5. Should I still insist on a certificate for polki jewellery?

A5. Yes, every time. Ask for GIA or IGI on the stone and check BIS hallmarking on the gold.

Q6. Does lab-grown polki hold value if I want to resell it later?

A6. Not as well as natural right now. The resale side of the lab-grown market in India is still catching up.

Q7. Is polki only used for wedding jewellery?

A7. It traditionally has been, but people are now wearing more lightweight and small lab-grown polki jewellery as everyday jewellery.
