What's the difference between kundan and polki jewelry quality?
Direct answer: The core quality difference is the stone itself — polki jewellery is set with natural, uncut, unpolished diamonds, while kundan refers to the 24K refined-gold-foil setting technique, which most often holds glass or gemstone pieces rather than diamonds. That is why genuine polki commands a significantly higher price, carries diamond-level heirloom and resale value, and is graded by stone clarity, whereas kundan quality is judged by the purity of its gold foil, the finesse of the setting, and the meenakari (enamel) work on the reverse.
Shoppers often use "kundan" and "polki" interchangeably because the two crafts look similar and frequently appear in the same bridal set. Technically, they answer two different questions: polki tells you what the stone is (a raw, natural diamond), and kundan tells you how a stone is held (wrapped in strips of highly refined gold, worked cold without solder or prongs). Understanding this distinction is the single most important step in judging quality — and price — correctly.
Key Takeaways
- Polki is a natural, uncut, unpolished diamond; kundan is a 22K gold-foil setting technique that usually holds glass or gemstones.
- Polki quality is graded by the stone — Syndicate polki (fewer inclusions, higher lustre) outranks Kilwas polki.
- Kundan quality is judged by gold purity, unbroken foil borders, and meenakari enamel work on the reverse.
- Polki costs several times more than comparable kundan and holds higher heirloom and resale value.
- Always ask for natural-diamond certification, BIS hallmarking, and an itemised weight breakdown (gold / polki / lac / meenakari).
≈ 2,500 years The uncut-diamond (polki) craft in India dates back roughly two and a half millennia, refined under Mughal patronage and later adopted by Rajput and royal households across the subcontinent — including the Nizams of Hyderabad, whose treasury drew on Golconda diamonds mined in what is now Telangana.

Kundan vs Polki: quality markers compared
| Quality marker | Polki | Kundan |
|---|---|---|
| What it actually is | A natural diamond left uncut and unpolished, retaining its raw crystal form | A setting technique using strips of highly refined (near-24K) gold worked around a stone, without solder |
| Centre stone | Real uncut diamond — no two stones are alike | Usually glass, quartz, or coloured gemstones; diamonds only in polki-kundan hybrids |
| Stone grading | Graded by transparency and inclusions — top-tier "Syndicate" polki is near-colourless with few inclusions; "Kilwas" polki shows more inclusions and costs less | No diamond grading applies; quality rests on gold purity, foil work, and stone-setting precision |
| Sparkle character | Soft, deep, watery glow from the foil-backed raw diamond | Bright surface shine from polished glass/gems and gold foil |
| Craftsmanship test | Evenness of the foil back, secure jadau (lac) setting, fine meenakari on the reverse | Uniform, unbroken gold-foil borders; smooth stone seating; detailed enamel reverse |
| Certification | Should come with a natural-diamond authenticity certificate and a transparent weight breakdown (gold / polki / lac / meenakari) | Should carry BIS hallmarking for the gold and a clear disclosure of stone material |
| Price band | Premium — priced like diamond jewellery; a bridal set is typically several times the cost of a comparable kundan set | More accessible — you pay chiefly for gold weight and artisanship, not stones |
| Heirloom & resale value | High — natural diamonds plus gold retain and often appreciate in value | Moderate — value rests mainly in the gold content and craftsmanship |
| Best suited for | Bridal trousseaus, investment-grade heirlooms, milestone gifting | Festive and occasion wear, larger statement looks on a defined budget |
How to check polki quality before you buy
- Ask which grade of polki is used. Trade labs such as GSI distinguish Syndicate polki (higher lustre, fewer inclusions, harder to source in large sizes) from Kilwas polki (more included, more affordable). A trustworthy jeweller will tell you which you're paying for.
- Insist on a weight breakdown. Traditional jadau settings use lac (a natural resin) beneath the stones. Reputable retailers now itemise gold, polki, meenakari, and lac weights separately so you know exactly what portion of the piece is precious metal.
- Confirm the diamonds are natural. Independent lab certification matters more than ever, as undisclosed lab-grown polki has begun entering the market. Certification from a recognised gemmological laboratory rules this out.
- Look for uneven, organic sparkle. Real polki has a natural, slightly irregular glow; a perfectly uniform shine usually signals glass.
How to check kundan quality before you buy
- Check the gold-foil borders. Fine kundan work shows continuous, tightly burnished gold strips around every stone with no gaps, lifting, or dull patches.
- Turn the piece over. The reverse of high-grade kundan carries detailed meenakari enamel — a hallmark of genuine Rajasthani/Hyderabadi artisanship, not a mass-produced casting.
- Verify BIS hallmarking on the gold components, and ask for written disclosure of whether the set stones are glass, quartz, or gemstones.
- Assess weight and balance. Quality kundan feels substantial for its size; very light pieces often indicate heavy filler or thin foil.
Which should you choose?
Choose polki when the piece is meant to be an heirloom or a bridal investment — you are buying natural diamonds whose value endures across generations. Choose kundan when you want the same regal Mughal-era aesthetic in a grand, wearable format at a friendlier price point. Many Hyderabadi brides do both: a polki bridal set for the wedding day, complemented by kundan pieces for the sangeet, reception, and festive seasons that follow.
At Krishna Jewellers Pearls & Gems — serving Hyderabad since 1983 from the historic Charminar pearl-market district — every polki piece is sold with natural-diamond certification and a transparent component-weight breakdown, and every kundan piece carries BIS-hallmarked gold. Our craftsmen work in the same jadau tradition that once served the Nizam's court.
Frequently asked questions
What's the difference between kundan and polki jewelry quality?
Polki jewellery is set with natural uncut diamonds, so its quality is graded by the stone's transparency and inclusions (Syndicate grade being the finest). Kundan is a 24K gold-foil setting technique usually holding glass or gemstones, so its quality is judged by gold purity, foil craftsmanship, and meenakari detail. Polki therefore costs more and holds higher resale value; kundan offers the same royal aesthetic at a more accessible price.
Is polki more expensive than kundan?
Yes. Because polki uses real, natural uncut diamonds, a polki set is typically several times the price of a visually similar kundan set, where the cost lies mainly in gold weight and artisanship rather than stones.
Does kundan jewellery use real diamonds?
Traditionally, no — kundan settings most often hold shaped glass or coloured gemstones. When a kundan-set piece contains uncut diamonds, it is properly called polki (or polki-jadau) jewellery.
Which holds value better, kundan or polki?
Polki holds value better because natural diamonds and gold both retain intrinsic worth and are prized as heirlooms. Kundan's resale value comes primarily from its gold content, so it is best bought for its beauty and craftsmanship rather than as an investment.
How do I know if polki diamonds are real?
Look for an uneven, natural glow rather than uniform shine, ask for the polki grade (Syndicate or Kilwas), request a natural-diamond certificate from an independent gemmological lab, and insist on an itemised weight breakdown separating gold, polki, lac, and meenakari.
