Every Raisoni Jauharis piece begins in Surat, Gujarat, the city where most of the world's diamonds are cut and polished. Raisoni Jauharis is a lab grown diamond jewellery brand with manufacturing roots in this city, and that single fact shapes how our jewellery is designed, made, priced and checked.
Most buyers only ever see the finished ring or pendant in a photo. In this guide we open the workshop door and walk you through the full journey of a piece, from a tiny diamond seed to the jewellery you wear. By the end, you will know exactly what goes into the price you pay, what quality looks like at each stage, and what questions to ask any jeweller.
Key takeaways
- Surat is widely reported to cut and polish around 90 percent of the world's diamonds, and Raisoni Jauharis has its manufacturing roots here.
- A lab grown diamond is real diamond, grown by CVD or HPHT, then cut and polished exactly like a mined diamond.
- Every stage, from planning to setting, affects how much a piece sparkles and how long it lasts.
- Raisoni Jauharis provides IGI and HRD Antwerp certification, 9K, 14K and 18K gold options, and a price breakup on many product pages.
- Orders typically deliver within 2 to 3 weeks, with free shipping above ₹49,999.
Why Surat is the diamond capital of the world
A city built on diamond skills
Surat's diamond industry grew over several decades into the largest cutting and polishing centre on earth. International reporting by AFP in 2024 described Surat as the city where around 90 percent of the world's diamonds are cut and polished. Thousands of polishing units, planners, cutters and setters work here, many of them in families that have practised the craft for generations.
How Surat embraced lab grown diamonds
As lab grown diamonds grew in popularity, Surat adapted quickly. Industry representatives from the Gem and Jewellery Export Promotion Council (GJEPC) have noted that a meaningful share of Surat's polishing units moved into lab grown diamonds within just a few years, and India has become a leading producer of CVD-grown diamonds. The same cutting skill that serves natural diamonds now serves lab grown ones.
What this means for a jewellery brand
Being rooted in this ecosystem gives a brand three practical advantages:
- Shorter supply chains. Fewer intermediaries between the diamond and the finished piece.
- Direct access to skill. Conversations about cut, polish and setting happen with the people who actually do the work.
- Faster customisation. Design changes can be discussed and made without passing through several companies.
This is the foundation of the manufacturer-led approach at Raisoni Jauharis.
Stage 1 Growing the diamond
What a lab grown diamond actually is
A lab grown diamond is carbon arranged in the same cubic crystal structure as a natural diamond. GIA explains that lab grown diamonds share essentially the same chemical, physical and optical properties as mined diamonds. The only difference is origin. One formed deep in the earth over a very long time, the other was grown in a controlled environment over weeks.
The CVD method
In Chemical Vapour Deposition, a thin diamond seed plate is placed inside a sealed chamber. A carbon-rich gas mixture is energised, and carbon atoms settle on the seed layer by layer, building a rough diamond crystal. CVD is widely used for larger stones and allows growers to control conditions closely.
The HPHT method
High Pressure High Temperature growth recreates conditions similar to those deep inside the earth. Carbon is exposed to intense pressure and heat until it crystallises as diamond. HPHT is common for smaller stones and is also used as a post-growth treatment to improve colour in some CVD diamonds.
Does the method matter to you
Both methods produce real diamond. What matters to the wearer is the finished stone's cut, colour and clarity, and whether any treatment is disclosed. A reputable grading report records the growth method where known. For a deeper comparison, read our guide to CVD vs HPHT lab grown diamonds.
Stage 2 Planning, cutting and polishing
Planning the rough
A rough crystal looks nothing like a finished diamond. Planners scan it with specialised equipment to map its shape, inclusions and possible outcomes. They decide which shape and proportions will give the best balance of size, brilliance and yield. A good plan can be the difference between a lively stone and a dull one.
Cutting and faceting
Cutters then shape the stone and create its facets. A round brilliant has 57 or 58 facets, each placed at precise angles so light enters the stone, bounces internally and returns to the eye as sparkle. Small errors in angles let light leak out of the bottom of the stone.
Polishing
Polishers bring every facet to a mirror finish. Polish and symmetry are graded on reports because they affect how cleanly light travels through the diamond.
Why cut matters most
Of the 4Cs, cut has the biggest effect on visible beauty. A well-cut stone of modest colour can look brighter than a poorly cut stone with a better colour grade. Our guide on how to choose diamond jewellery explains all four Cs.
Stage 3 Independent grading and certification
What a grading report records
Qualifying stones are sent to independent gemmological laboratories. A report typically records the diamond's origin as lab grown, along with shape, measurements, carat weight, colour, clarity, cut details where applicable, polish, symmetry and any disclosed treatment. Many reports also note a laser inscription on the girdle that links the stone to its report.
IGI and HRD Antwerp
Raisoni Jauharis provides IGI and HRD Antwerp certification with its jewellery. Both are established laboratories with online report verification. We compare them in detail in our IGI vs HRD Antwerp guide.
How to verify a report yourself
- Find the report number on your certificate.
- Enter it on the laboratory's official verification page.
- Check that the details shown match your certificate and your stone.
Stage 4 Designing the jewellery
From idea to sketch
Every design starts with an idea: a reference image, a customer's sketch or a trend our designers want to interpret. The design team decides the shape, the number and size of diamonds, and how the piece should sit on the body.
Precision CAD modelling
The design is then built as a precise 3D CAD model. CAD controls the height of a setting, the thickness of a shank, the size of each prong and the exact placement of every stone before any metal is used. It also lets customers see realistic renders and request changes early. Read more in From Imagination to Creation.
Designing for comfort and strength
Good CAD work balances beauty with wearability. Rings need a comfortable inner edge, earrings need balanced weight, and bracelets need links that flex without straining. These decisions are made on screen, long before production.
Stage 5 Casting in gold
From model to metal
The approved CAD model is printed in resin or wax. This model is set in a mould, the wax or resin is burned out, and molten gold is poured in to create the metal piece. The rough casting is then cleaned, trimmed and refined.
Choosing the gold purity
Raisoni Jauharis pieces are commonly available in 9K, 14K and 18K gold, in yellow, rose and white tones.
| Purity | Gold content | Best for |
|---|---|---|
| 9K | 37.5% | Budget-friendly, durable everyday pieces |
| 14K | 58.5% | Daily-wear rings, studs and bracelets |
| 18K | 75.0% | Fine, bridal and statement jewellery |
Our 9K vs 14K vs 18K guide explains colour, durability and price differences, and our BIS hallmark guide shows how to verify gold purity.
Stage 6 Setting the diamonds
Common setting styles
- Prong. Small metal claws hold the stone and let in maximum light.
- Bezel. A metal rim surrounds the stone for strong protection.
- Pavé. Many small diamonds set closely for a continuous sparkle.
- Channel. Stones sit between two metal walls, ideal for bands.
Compare the two most popular styles in bezel vs prong settings.
Why setting is where craftsmanship shows
Setting is skilled, careful work, often done under magnification. Stones should sit level, prongs should hold firmly without snagging, and the metal around each stone should look clean. A poorly set stone can loosen over time, which is why setting quality matters as much as the diamond itself.
Stage 7 Finishing and final checks
Polishing and plating
The piece is polished to a smooth finish. White gold pieces are usually plated with rhodium for a bright white colour. The piece is then cleaned to remove polishing residue.
Quality inspection
Before dispatch, we check stone security, symmetry, finish, clasp function and that documentation matches the piece. Our full 12-point quality checklist explains each check and how you can do a quick version yourself.
Stage 8 Delivered to you
Orders typically deliver within 2 to 3 weeks, packed securely with their documentation. Shipping is free on orders above ₹49,999. We recommend recording a short video when you open the parcel, matching the invoice and certificate with the piece, and contacting us immediately if anything looks wrong.
