The Lab Grown Diamond Supplier Built for Serious Buyers
IGI certified CVD and HPHT lab grown diamonds, sourced direct from Surat’s manufacturing ecosystem. Transparent pricing. Zero compromise on certification. Built for wholesalers, retailers and manufacturers.
What Are Lab Grown Diamonds — And Why Do They Matter?
Lab grown diamonds are real diamonds. They share the same chemical composition (pure carbon), the same crystal structure, the same optical properties, and the same hardness (10 on the Mohs scale) as mined natural diamonds. The only difference is origin — they are grown in a controlled laboratory environment rather than formed over billions of years beneath the earth’s surface.
There are two primary growth methods: CVD (Chemical Vapour Deposition) — where a diamond seed crystal is exposed to a carbon-rich gas mixture that deposits carbon atom by atom — and HPHT (High Pressure High Temperature) — which replicates the intense geological conditions under which natural diamonds form.
For retailers and wholesalers, lab grown diamonds represent a significant market opportunity: stones that are optically and chemically identical to natural diamonds, at price points that open new consumer segments and improve margin structures across bridal, fashion, and fine jewellery categories.
Chemically Identical
Pure carbon crystal structure — identical to mined diamonds at the atomic level.
Visually Indistinguishable
Cannot be differentiated from natural diamonds by the naked eye or standard jewellery loupe.
IGI Certified
Every lab grown diamond we supply carries a full IGI grading report with cut, colour, clarity and carat.
Consistent Supply
Controlled production means consistent availability — no rough market volatility affecting supply timelines.
Global Demand Growth
Lab grown diamond retail adoption in the U.S. has grown significantly — particularly in bridal and fashion jewellery.
Margin Opportunity
Lower per-carat cost relative to natural diamonds creates retail pricing flexibility and margin expansion.
Why Source Lab Grown Diamonds From Surat?
Surat is not just the world’s cutting and polishing capital for natural diamonds — it has rapidly become the dominant global hub for lab grown diamond processing too. The infrastructure, skilled artisan workforce, and proximity to CVD reactor manufacturers make it the most efficient point in the world to source polished lab grown diamonds.
Proximity to CVD Reactor Manufacturers
Many of India’s CVD diamond growth facilities are based in and around Gujarat — reducing transit time from reactor to polishing bench to lab submission to export.
Mature Polishing Expertise
Surat’s workforce of over one million skilled diamond workers brings the same precision polishing expertise to lab grown stones that has made it the world’s natural diamond processing capital.
Cost Efficiency Without Compromise
Lower operating costs relative to Antwerp, New York or Tel Aviv — combined with direct manufacturer access — means better pricing at the same or higher quality standard.
IGI Lab Access
IGI’s Surat office provides rapid turnaround on lab grown diamond certification — typically faster than submission through western hubs — reducing lead times on certified inventory.
Established Export Infrastructure
Surat’s export ecosystem — freight forwarders, customs agents, insurance providers — is fully equipped for regular international diamond shipments to the USA, UK, and UAE.

Private Label Supply
Manufacturers and branded jewellery labels can work with us on specification-matched lab grown programs aligned to their production schedules and quality requirements.
CVD vs HPHT — Which Lab Grown Diamond Should You Buy?
Both CVD and HPHT produce genuine diamonds. The choice between them depends on your product application, customer expectations, and pricing strategy. Here’s what you need to know.
CVD
Chemical Vapour Deposition
- Carbon-rich gas is introduced into a vacuum chamber where it deposits carbon atom by atom onto a diamond seed crystal
- Produces Type IIa diamonds — the purest form of diamond, rare in nature
- Generally available in a wider range of large sizes (3ct+)
- The dominant method in Surat’s lab grown production ecosystem
- Slightly lower production cost at larger sizes vs HPHT
- May require post-growth treatment for colour improvement in some stones — declared on IGI certificate
- The preferred choice for high-end bridal, solitaire, and fashion jewellery programs
HPHT
High Pressure High Temperature
- Replicates the geological conditions under which natural diamonds form — extreme pressure and temperature applied to a carbon source
- Produces diamonds with a slightly different crystal growth pattern to CVD
- Particularly strong for fancy colour diamonds — especially yellow and pink
- Often preferred for smaller sizes and melee production
- Well-established technology with a long track record in jewellery trade acceptance
- Typically does not require post-growth colour treatment
- Well-suited to fashion jewellery, coloured stone programs, and parcel supply
IGI Certification — The Global Standard for Lab Grown Diamonds
The International Gemological Institute (IGI) is the world’s leading certification body for lab grown diamonds. Every lab grown diamond we supply carries a full, verifiable IGI grading report — no exceptions.
Why IGI — Not GIA — for Lab Grown?
IGI was the first major lab to develop a dedicated grading protocol for lab grown diamonds and has processed significantly more lab grown stones than any other certification body. IGI reports are the industry standard accepted by U.S., UK, and UAE retailers and wholesalers for lab grown inventory.
What an IGI Lab Grown Report Covers
Each IGI report details: carat weight, shape, measurements, cut grade, colour grade, clarity grade, fluorescence, growth method (CVD or HPHT), and whether any post-growth treatment has been applied. The report is laser-inscribed with a unique ID on the diamond’s girdle.
Laser Inscription & Traceability
All IGI certified lab grown diamonds above a certain size carry a laser-inscribed report number on the girdle — verifiable online at any time. This inscription confirms the stone’s identity and makes misrepresentation essentially impossible at the retail level.
Our Certification Process
We manage the full IGI submission and retrieval process on your behalf — from sorting and packaging through lab submission, result review, and certificate matching. We review all results before shipment and flag any grade discrepancies against your specification before proceeding.
Turnaround Times
IGI Surat typically provides lab grown grading reports within 5–10 business days for standard service. Express services are available for urgent programs. We build certification timelines into every procurement schedule so there are no surprises on delivery dates.
No House Certificates
We do not supply lab grown diamonds with manufacturer certificates, house grades, or reports from non-recognised laboratories. Every stone we sell is IGI certified — full stop. Your customers and downstream buyers will never be left with unverifiable grading claims.
From Enquiry to Delivery — Our Sourcing Process
We operate a structured procurement process for every order — whether you’re placing a first trial order of 10 stones or establishing an ongoing replenishment program for hundreds of carats per quarter.
Specification Mapping
We document your precise requirements — shape, carat range, colour/clarity window, growth method preference (CVD or HPHT), certification requirements, and target pricing band. This becomes the sourcing brief we work to.
Sourcing & Selection
We source against your brief from our Surat manufacturing network. Stones are shortlisted against your specification before being presented with full measurement details and pre-certification grading information.
IGI Certification Submission
Approved stones are submitted to IGI Surat for full grading. We manage the submission, monitor progress, and review results against your specification before accepting certificates.
Pre-Shipment Inspection
Every order undergoes a pre-shipment review — physical inspection against certificates, stone-by-stone matching, and video documentation provided to you for approval before packing.
Export Documentation
We prepare all export documentation — commercial invoice, packing list, insurance certificate, and country-of-origin documentation — in the format required by your destination country’s import requirements.
Insured International Shipment
Diamonds ship via established international diamond courier with full transit insurance. Tracking is provided from despatch to delivery. Post-delivery support available for any documentation or query requirements.

Natural vs Lab Grown — Positioning Both for Your Retail Program
Understanding where natural and lab grown diamonds sit relative to each other — and how to position both to your customers — is essential for any retailer building a complete diamond offering.
| Factor | Natural Diamonds | Lab Grown Diamonds |
|---|---|---|
| Chemical Composition | Pure carbon crystal — identical | Pure carbon crystal — identical |
| Visual Properties | Indistinguishable to naked eye | Indistinguishable to naked eye |
| Hardness (Mohs) | 10 — hardest known material | 10 — hardest known material |
| Origin | Formed over billions of years beneath the earth | Grown in controlled laboratory environment |
| Certification Standard | GIA or IGI (both widely accepted) | IGI (dominant industry standard) |
| Price Point (per carat) | Higher — scarcity-driven market | Lower — technology-driven supply |
| Price Stability | Relatively stable with Rapaport benchmarking | Prices have declined significantly — now stabilising |
| Consumer Perception | Heritage, rarity, traditional sentiment | Modern, accessible, ethical alternative |
| Retail Margin Structure | Standard wholesale-to-retail margin | Often higher % margin due to lower cost base |
| Best Application | Heritage bridal, investment-oriented buyers, high-value pieces | Fashion, accessible bridal, younger consumers, gift purchase |
| Supply Consistency | Subject to rough market and polishing pipeline | More consistent — technology-controlled production |
Our Recommendation for Retailers
The most successful jewellery retailers don’t choose between natural and lab grown — they stock both, positioned clearly for different customer motivations. A heritage bridal customer seeking rarity and tradition will gravitate toward natural. A modern buyer prioritising size, accessibility, or value will choose lab grown. Stocking both with clear, confident positioning allows you to serve the full market without losing either customer. We supply both categories with equal quality discipline and certification rigour — making us the only sourcing partner you need for your diamond inventory.
