The polki vs diamond question usually comes up when a family is pricing a heavy wedding set in lakhs, and the honest answer surprises people: both are diamond. What separates them is the cut, the way they are set, how much gold surrounds them, how heavy the set feels by the end of the pheras and whether the bride will wear it again. This guide works through those decisions for a bride and her family. For the short glossary of polki, kundan, lab-grown and American diamond, see our guide to custom bridal jewellery sets.
What is a polki diamond?
A polki is a natural diamond cut as a flat slice and polished without the full set of facets a modern diamond carries. According to GIA, polki is one of the oldest forms of cut diamond and originated in India; the stones often keep something of their rough form and have an unfaceted, polished surface. Sellers often call polki "uncut", but in practice it is lightly cut, not raw.
Modern polki is made with modern tools. A Mumbai jeweller quoted by GIA explains that the stones are laser-sawn into slices and then polished or lightly faceted by machine, and that manufacturers use highly included or cloudy rough that still has good colour, because it would yield very little as a modern cut. So the inclusions you see in polki are expected. They are part of the look, not a defect being hidden.
Because of that, polki is rarely graded stone by stone. A faceted diamond in a bridal set is described by a colour range and a clarity grade on the listing or invoice. Colour runs from D (colourless) downwards, and clarity describes what shows under 10x magnification.
Polki vs diamond: how they differ in a bridal set
Polki gives a soft glow in a heavy, closed gold setting; faceted diamonds give sparkle in a lighter, open setting. The table compares them on the points that decide how a set looks, feels and lasts.
| Factor | Polki | Faceted diamond |
|---|---|---|
| Cut | Flat slice, polished, unfaceted or lightly faceted | Many facets (round, oval, pear and others) cut to return light |
| Look | Soft glow; takes colour from the foil and gold around it | Bright white sparkle with flashes of colour |
| Stone quality | Often included or cloudy, chosen for colour and size | Graded for colour, clarity and cut |
| Setting | Set into gold in the kundan or jadau manner, closed back, often foil behind the stone | Prongs, pavé or bezel, usually open at the back to let light in |
| Usual gold | High-purity gold around each stone | 18K or 14K gold, which grips stones firmly |
| Weight | Heavier for the same coverage, because gold surrounds and backs every stone | Lighter, because the metal is a frame |
| Paperwork | Total polki weight on the invoice; individual reports are uncommon | Total carat and grade on the invoice; a report for larger stones |
| Wear after the wedding | Festive and family occasions | Easier to wear to work, dinners and smaller functions |
GIA's source adds that polki is usually backed with silver foil and enamelled at the back, in the manner of most traditional Indian jewellery. The foil is why polki looks warm and why it must be kept dry.
Kundan vs diamond: are they the same thing?
No. Kundan is a way of setting stones in gold, while a diamond is a stone. The V&A museum describes kundan as a historic Indian process in which pure, soft 24-carat gold is used to set gemstones, a technique most closely associated with the Mughal court.
That has a practical consequence for buyers. A "kundan set" tells you how the stones are held, not what they are. It may hold polki, coloured gemstones or glass, and the price should reflect which. Many jewellers use "jadau" for the whole craft of setting stones into gold this way and "kundan" for the gold work itself, and usage varies between workshops, so ask what the stones are and get it written on the bill.
Polki or diamond: which is more expensive?
Per carat, polki is usually much cheaper than a faceted diamond, but a polki set can cost as much or more overall because of its gold weight and handwork. GIA's source makes both points: polki is usually much less expensive than round brilliants, yet the lower per-carat price does not always mean a lower price in the shop, because there are no ready-made settings and everything is done by hand.
| Where the money goes | Polki set | Faceted diamond set |
|---|---|---|
| Stones | Lower price per carat, but often many carats | Higher price per carat; the main cost in stone-heavy pieces |
| Gold | Often the largest line, because the setting is heavy | Large in Indian bridal designs, smaller in light pieces |
| Labour | Hand setting, foiling and enamel work on the reverse | Casting, setting and polishing, often partly mechanised |
| Other stones | Emeralds, rubies, pearls and enamel are common | Usually diamonds only, sometimes with coloured stones |
For scale, the small faceted diamonds in natural diamond pieces we checked on one national jeweller's website on 22 October 2026 were costed at about ₹1.15 lakh per carat, before its festive discount on stone value. Polki has no comparable published rate. If you are comparing a polki quote with a diamond quote, ask each for the stone weight, the net gold weight and purity, and the making or setting charge, then compare line by line. Our guide to diamond price per carat in India explains why per-carat rates rise with size.
Do polki diamonds have resale value?
Polki is bought to be worn and passed down, not as an investment. If a polki piece is exchanged, the gold is usually valued by its weight and purity, and the stones, enamel and handwork recover much less than they cost. Ask whether the stones are treated, and ask for exchange and buyback terms in writing before you pay.
How polki and diamonds look and feel on the day
Polki reads as traditional and warm; faceted diamonds read as bright and modern. The choice usually follows the outfit, the light and how long the bride will wear the set.
- Outfit. Polki sits naturally with deep reds, maroons, heavy zardozi and gold-toned lehengas. Faceted white diamonds suit ivory, pastels, reception gowns and lighter saris.
- Light. A designer quoted by GIA calls the light from polki much softer than the sparkle of modern cuts. Under stage and evening lighting, faceted diamonds throw more sparkle.
- Weight. Closed-back polki necklaces, rani haars and matha pattis can be heavy over a long ceremony. Ask for the weight in grams of each piece, and try the necklace on with the dupatta pinned.
- Ageing. Foil and enamel last well when kept dry. Moisture, perfume or cleaning liquids that get behind a closed setting cannot be rinsed out, so polki should never go in an ultrasonic cleaner.
How to mix polki and diamonds in one bridal wardrobe
Let one piece lead each look and keep the other quieter, and use the same gold colour across both. Mixing is common and works well when it is planned.
| Function | A balanced way to combine them |
|---|---|
| Wedding ceremony | A polki necklace or rani haar, with polki or family gold earrings and maang tikka |
| Sangeet or mehendi | Faceted diamond earrings with a light necklace, or no necklace |
| Reception | A faceted diamond necklace and earrings, often in white or rose gold |
| After the wedding | Faceted diamond studs, drops, rings and a bangle, worn regularly |
Some pieces combine both: a polki centre framed by small faceted diamonds, or faceted diamond drops hung from a polki top. These give the traditional look with more sparkle. If the family already has polki or kundan pieces, photograph them and plan the faceted pieces around them, so that the gold colour and proportions match.
What is lab-grown polki, and what does it cost?
Lab-grown polki is laboratory-grown diamond cut into flat polki-style slices and set in traditional designs. It is real diamond, like all laboratory-grown diamond, and it is new: an Indian trade publication reported a lab-grown uncut collection being launched in 2024, and only a handful of brands sell it.
Sellers present it as clearer and more uniform than natural polki, and as a way to make lighter pieces. Those are seller claims, and one consequence is worth weighing: the cloudy, included character of natural polki is part of its traditional look, and a very clear lab-grown slice can look different. Whether that matters is a family's call. Our comparison of lab-grown and natural diamonds for wedding jewellery covers the family conversation.
We found no published per-carat price for lab-grown polki at the time of writing. For comparison, faceted laboratory-grown diamonds in itemised Indian listings we checked on 22 October 2026 were costed at roughly ₹19,000 to ₹51,000 per carat. Whatever the price, India's diamond terminology standard, IS 19469:2025, expects such stones to be described in full as "laboratory-grown diamond" on the bill.
How to check a polki or diamond set before you pay
Get the stone type, stone weight, gold purity and net gold weight in writing for every piece. Polki and kundan pieces are harder to check at home than faceted diamonds, so the paperwork matters more.
- Ask what the stones are: natural polki, laboratory-grown polki, faceted diamond, coloured gemstone or glass.
- Ask for the total stone weight of each type, and whether any stones are treated.
- Ask for the gold purity and the net gold weight, separate from stones, enamel and any filling.
- Check hallmarking. The Bureau of Indian Standards lists kundan, polki and jadau articles among the exemptions from mandatory gold hallmarking, so an unhallmarked polki piece is not automatically suspect, but the invoice should still state the purity.
- For faceted diamonds, ask for a report on any significant stone and the grade range of the small ones.
- Get exchange, buyback and repair terms in writing.

How AXIOM approaches this
AXIOM's bridal commissions are set with natural or lab-grown diamonds in 14K or 18K gold, at the Bharat Diamond Bourse in Mumbai. If family polki or kundan pieces are part of the wedding, bring photographs of them and of the outfits: a bespoke piece can be designed to sit beside them, with design options at every stage and the piece shown on a model before it is made. Wedding-season commissions should start early, so confirm timing through our contact page.
The practical takeaway
Choose polki for the heavy, traditional ceremony look and faceted diamonds for the pieces that will be worn again, and do not assume either is the cheaper option until you have the stone weight, net gold weight and making charge for each in writing. Ask what every stone is, keep polki dry, and treat both as jewellery to wear and pass on, not as an investment.
