If your current lab-grown diamond supplier keeps running out of stock, ships inconsistent quality, or goes quiet after the order you are not alone.

A Reliable LGD Partner
Looking for a reliable lab-grown diamond manufacturer in Surat?
Many jewelers and wholesalers from the USA, UAE, UK and Europe face the same challenge: their current supplier runs out of stock mid-season, ships mismatched quality, or stops responding after the order.
We supply lab-grown diamonds in bulk with consistent quality and the best price — serving man-made diamonds to wholesalers and jewelers in 15+ countries. We're here for steady supply, not one-time deals. We deal in HPHT and IGI-certified lab-grown diamonds, matched to your exact requirements.
As a Surat-based CVD & HPHT diamond manufacturer, we maintain bulk production capacity and ready inventory across all sizes, shapes and clarity grades — from 0.01 ct melee to 30+ ct statement stones. IGI / SGL certified per your requirement.
Our Focus Is Simple
Six promises we keep, on every parcel.
With strong in-house production and ready inventory, we help you avoid delays and last-minute sourcing problems. Whether you need round brilliants, fancy shapes or custom specifications — we deliver what you ask for.
01

Quality control happens at every stage — rough selection to final polish. What you approve in the sample is what you receive in bulk.
02
Keep the Supply Stable, Always
Ready inventory of CVD and HPHT lab-grown diamonds across all sizes and shapes. Orders dispatch on time, every time.

Why Choose Us
Why wholesalers & jewelers choose
Arihant Lab Diamond.
In-House Manufacturing in Surat
Rough buying, planning on Sarine, sawing, 4P, polishing and grading — all in-house. Tighter QC, faster turnaround, no inflated pricing.
CVD + HPHT Under One Roof
Most suppliers specialize in one technology. We manufacture both — pick by product, client preference or target price.
Full Range 0.01 ct to 30+ ct
Very few Surat manufacturers carry this range. Melee for pavé, mid-range for solitaires, 10–30+ ct collector stones.
IGI Certification on Every Stone
IGI / SGL certificates available per request — confidence for regulated USA, UK, UAE and Australia markets.
Strict Quality Matching Before Dispatch
Each stone color, clarity, cut, carat matched against your spec sheet. What you confirm is what ships.
Scalable Supply for Growing Businesses
From 100 pieces to 5,000 — production capacity and mindset built for your growth.
Problems We Solve
Common LGD supplier problems — and
how we solve them.
Problem 1
Stock runs out at the worst time
You commit to a buyer, but mid-season your supplier says they're out of matching stock.
How We Solve It
We keep ready stock across popular sizes, shapes and clarity grades. When you order, we don't scramble — we dispatch.
Problem 2
Quality mismatch after delivery
Your spec was correct — but the parcel that arrived was a different color, clarity or cut. Trust broken.
How We Solve It
Our matching process verifies every parcel against your approval before dispatch. No after-delivery complaints.
Problem 3
Pricing changes without warning
You quoted your client based on the supplier's rate. The supplier revises silently — your margin collapses.
How We Solve It
Upfront pricing, clear revision communication per stone. No post-order surprises. You plan with certainty.
How We Supply
From Surat to your door.
A supply process designed for B2B buyers — jewelers, wholesalers and diamond traders who require clarity, speed and reliability at every stage.
Share Your Requirement
Carat, color, clarity, shape, technology, certification, quantity. A spec sheet works best — use our RFQ form or email.
Get Matched Stones + Certificates
We sort matching selections, verify each stone against your spec, and send IGI/SGL certificates via email or WhatsApp.
Approve Quality and Pricing
Review certificates, photos and videos at your end. Once approved, we send a detailed sheet with each stone and total.
