The nath is the one bridal piece that is worn on the face itself, so it has to suit the bride's features, sit comfortably for hours and survive photographs at close range. Most of what turns up in a search is traditional pearl and gold work, kundan, or imitation stones. This guide is for the bride or family who wants real diamonds in a nath or nose pin, whether on its own or as part of a set, and it covers the questions most product pages skip: which style belongs to which tradition, how much weight a nostril should carry, and what to tell a jeweller.
Why do brides wear a nath, and which style is yours?
The nath is a customary part of bridal dress in many Indian communities, not all of them, and its form changes from region to region. In some families it marks a married woman or is a gift from a particular relative; in others it is simply part of the wedding look. No bride is obliged to wear one, and many choose a small stud instead.
| Tradition | Customary form | Notes |
|---|---|---|
| Maharashtrian | A cashew-shaped nath of pearls and gemstones in yellow gold, with a chain | Usually worn on the left nostril |
| Garhwali (Uttarakhand) | The Tehri nath, a large gold ring with a chain to the ear or hair | In many families, gifted by the bride's maternal uncle |
| Hyderabadi | A nose ring with a large ruby bead flanked by two pearls | Part of the khara dupatta ensemble |
| Bengali | A gold nath with a chain to the hair in many families; a smaller nolok or nakchabi stud is also worn | Names and placement vary by family |
| Rajasthani and Punjabi | Often a larger ring with an embellished chain into the hair | Size and ornament vary widely by family |
| Many South Indian families | Smaller nose studs, sometimes on both sides | A nath-style hoop is less common |
GIA's laboratory in Mumbai, describing two pearl naths it tested, notes that the classic nath is typically cashew shaped, with a chain to connect it to a hairpiece or earring, that it was made famous during Peshwa rule, and that it has been made with diamonds, pearls, rubies and emeralds. The Hyderabadi nath, with its ruby and pearls, is one piece of the khara dupatta ensemble. In Garhwal, the Tehri nath is in many families a gift from the bride's maternal uncle on the wedding day, and because the traditional piece is large and heavy, some brides now choose a lighter version.
Where a family nath carries that kind of meaning, a commissioned diamond piece usually sits beside it: worn for the reception or sangeet, or as the daily nose pin afterwards, rather than replacing the heirloom at the ceremony. Ask the family before you design.
What diamond nath designs are there?
A diamond nath can be a full nath with a chain, a smaller nathuni ring, a nose pin, or a traditional outline such as the Maharashtrian cashew reinterpreted with diamonds. The right one depends on custom, how often she will wear it, and whether she is pierced.
| Design | Typical size | Diamond work | Best for |
|---|---|---|---|
| Diamond nose pin | Head of 2 to 4 mm | A solitaire, or a flower of six stones around one | Daily wear after the wedding |
| Nathuni (small ring) | Ring of about 8 to 12 mm across | A row of small stones on the front half | Light bridal look, re-wear at festivals |
| Bridal nath with chain | Ring of about 20 to 40 mm across, or larger | Pavé on the ring, a drop or motif at the front | Wedding day, with a chain to the hair |
| Maharashtrian-style nath | Sized to the bride's face | Diamonds along the cashew outline, with or without pearls | A modern take worn alongside a family pearl nath |
For the stone sizes, millimetres are more useful than carats on a nose. On a standard round-brilliant size chart, a 0.07 carat stone measures about 2.7 mm, 0.10 carat about 3.0 mm and 0.15 carat about 3.4 mm. A single stone over about 3.5 mm reads as a statement on most noses. For a bridal nath, the sparkle usually comes from many small stones of 1 to 1.5 mm in pavé or a channel along the ring, with one larger stone or a pear drop where the eye lands.
How much weight can a nostril carry, and how is a nath secured?
Keep the part that rests on the nostril light, a few grams at most, and let the chain carry the rest of the weight to the hair or ear. Traditional naths are heavier than most people expect: the two pearl naths GIA tested weighed 9.05 g and 13.96 g in total. That works only because the chain takes the load.
- The chain: a fine chain from the nath to a hook pinned in the hair, or clipped to the earring, carries most of the weight. Ask for the chain length to be set on the bride, not to a standard.
- The fitting on a pierced nose: bridal naths usually pass through the piercing as a ring, with a small hinge or clasp. Nose pins use a screw back, a flat-disc screw back, an L-shaped post or a nose bone.
- Clip-on: a small pressure clip grips the outer nostril with no piercing. A clip cannot hold much, so a clip-on nath must be light and its chain must do almost all the work.
- Post thickness: nose pin posts are commonly 20 gauge (about 0.8 mm) or 18 gauge (about 1.0 mm). Tell the jeweller what your current pin measures so the new post fits.
If you plan to pierce for the wedding, ask your piercer how long your piercing needs before it can take a heavier piece, and pierce well ahead. A fresh piercing should not carry a bridal nath. Wear any nath, clipped or pierced, for an hour at home before the day.
Pierced or clip-on: which should you choose?
Choose pierced if she already has a piercing or wants to wear a diamond nose pin after the wedding; choose clip-on if she has no piercing and wants the nath only for the ceremony. A pierced nath can be a little larger and more secure. A clip-on keeps the decision reversible.
| Question | Pierced | Clip-on |
|---|---|---|
| Security | High, especially with a chain | Lower; relies on the clip and chain |
| Weight it can take | More, with a chain | Very little on the nose itself |
| Re-wear afterwards | Easy, as a nose pin | Occasional only |
| Lead time | The piercing must heal first | None |
Real diamonds, pearls or American diamond?
A real diamond nath is set with natural or laboratory-grown diamond; American diamond is cubic zirconia, a simulant that is softer and can yellow with time. Pearls are a separate, traditional choice, and many diamond naths keep a pearl or two for the familiar look.
If a "diamond nath" is priced at a few hundred or a few thousand rupees, the stones are not diamond. Neither is wrong to wear, but the price should match the material. Our guide on how to check a real diamond at home covers what you can and cannot test yourself, and why the invoice and a lab report matter more.
Natural or lab-grown diamonds for a nath?
Both are real diamonds and look the same once set, so the choice is about budget, family expectation and what the piece means to you. India's standard IS 19469:2025 says the word "diamond" alone may refer only to a natural diamond, and a lab-grown stone must be clearly described as a "laboratory-grown diamond", never "lab diamond".
| Question | Natural diamonds | Laboratory-grown diamonds |
|---|---|---|
| Real diamond? | Yes | Yes |
| Price for the same size | Higher | Usually much lower |
| Grading | Full colour and clarity grades from GIA and IGI | IGI gives full grades; GIA now gives "Premium" or "Standard" |
| Resale | Limited | Very limited |
The stones in a nath are small, so they are rarely certified individually; ask for the total carat weight, colour and clarity range on the invoice. Some families prefer natural stones for a piece with ritual weight and are relaxed about lab-grown for daily wear. Neither should be bought as an investment.
14K, 18K or 22K gold for a diamond nath?
18K gold (75% pure, hallmarked 750) suits most diamond naths; 14K (58.5%, hallmarked 585) is stiffer and better for thin posts and hinges; 22K (91.6%, hallmarked 916) is soft and best kept for plain gold or pearl work. A nose pin post or a nath hinge is fine metal under constant small stress, and a softer alloy bends sooner.
Weight is a second reason. 18K is roughly 10 to 15% lighter than 22K for the same design, and 14K roughly 20 to 25% lighter, depending on the alloy, which matters on a nostril. If the nath must match family pieces in 22K, ask to see the 18K yellow colour beside them. Our guide to 14K vs 18K gold explains the colour and wear differences, and every gold piece should carry a BIS hallmark with a six-character HUID.
How to brief a jeweller for a diamond nath
Bring the custom, the face and the measurements, not only a picture.
- The tradition you are following, and whether a family nath will also be worn.
- Pierced or clip-on, which side, and your current pin's post thickness.
- Two to four reference images, with what you like in each.
- The ring size across, tried as a wire or paper loop against the face in a mirror.
- Where the chain should end: a hair pin, the earring, or behind the ear.
- Diamonds: natural or laboratory-grown, stone shapes, and the largest stone size in mm.
- Pearls or gemstones to keep, if any.
- Metal: 14K or 18K, and the gold colour.
- A weight ceiling for the part on the nose, and a budget range.
- Whether a detachable diamond nose pin should be made to the same design for daily wear.
If the nath is part of a larger commission, our guide to custom bridal jewellery sets covers how to plan and budget the pieces together, and the diamond maang tikka guide covers the matching forehead piece.
How AXIOM approaches this
AXIOM makes bridal pieces, on their own or as a set, as bespoke commissions at the Bharat Diamond Bourse in Mumbai, in 14K or 18K gold. A nath can be commissioned alone, starting from any reference you bring and from the family's custom. We share several design options, show the design on a model before it is made, and choose the diamonds with you, natural or lab-grown. Wedding season runs from November to February and the Diwali weeks are our busiest, so start early and confirm timing through our contact page.
The practical takeaway
Ask the family which nath, if any, is customary, and keep any heirloom piece for the moments it belongs to. For a diamond nath, keep the weight on the nostril light and let a chain carry the rest, settle pierced or clip-on before the design, choose 18K or 14K gold for posts and hinges, and make sure the invoice names the diamonds plainly.
