B2B Jewelry Partner — Source · Manufacture · Fulfil
Launch a fine jewelry brand from anywhere in the world. We handle sourcing, manufacturing, and fulfilment — so you focus entirely on selling.
Browse our ready collections or brief us on a custom design. Share it with your customers. Only order when you have a sale.
We source the stones, manufacture the piece, pack it in your branded packaging, and ship it directly to your customer — anywhere in the world. You never touch the inventory. You never manage the logistics. You just sell.
No studio, no stockroom, no production team. Your brand runs on our infrastructure — and your customers never know the difference.
Your backend, finally running like a well-oiled engine.
From stone sourcing to your customer's doorstep — with nothing for you to manage in between.
The right stone. Every time. Guaranteed.
Operating from Surat and Mumbai — the heart of the world's diamond industry — we source across the full spectrum with complete transparency. Every stone comes with a certificate. Every price is what it is — no markups buried in the invoice, no surprises at the end.
Launch today. No design work required.
Browse our curated catalog of pre-designed fine jewelry — rings, pendants, earrings, and bracelets across multiple styles and price points. Choose what fits your brand, add your markup, and start selling.
Our design team works with you personally through our curated Lookbook — helping you explore styles, stone combinations, and metal options before committing to a single piece.
Ready collection designs are available across our partner network and are not exclusive. They are the fastest path to a live, sellable catalog.
Your design. Yours alone.
Brief us on a concept — a sketch, a reference image, a description — and our design team produces the CAD, renders, and a physical sample for your approval before a single gram of metal is cast.
Every custom design commissioned through Grandior is exclusive to your brand — permanently. We do not reproduce, sell, or offer it to any other partner, in your market or anywhere in the world.
Built to your spec. Finished to a standard your customers will notice.
Your pieces are cast, set, polished, and quality-checked to a designer-level finish in our partner ateliers. Every piece is inspected against your approved sample before it leaves the bench. We check every piece against your approved sample before it ships. That’s the process.
Your brand on the box. Delivered in 7 days.
From order confirmation to your customer's door in 7 days. We ship in your branded packaging, with your certificates and inserts, tracked and insured. Your customer receives a complete branded experience. They never know we exist.
Buy only when you have an order.
No inventory to hold. No pieces to buy before you have a sale. Sell first, order after — it’s that straightforward.
Book a Discovery CallWhen you commission a custom piece through Grandior, we build it to your exact specification — and we never offer it to anyone else. No other brand in your market, or anywhere in the world, gets access to your design. Ready collection pieces are available across our partner network and are not exclusive. The choice is always yours: move fast with our catalog, or build something that is entirely and permanently your own.
Sourced from the world's diamond capital — certified, transparent, and fairly priced.
Chemically, physically, and optically identical to mined diamonds — typically at 60–80% less than mined stones. Your customers are already asking for them. We make sure you can say yes.
For brands that serve customers who specifically want mined stones. Ethically sourced, fully certified, available across all grades and cuts. Every stone traceable to origin.
Ruby, Sapphire, Emerald — the classics. Heat-treated or untreated as specified, with certificates where required. For brands building coloured stone collections or bespoke commissions.
Tanzanite, Aquamarine, Amethyst, Topaz, Morganite, and more. For brands that want colour, character, and room to price competitively.
The highest refractive index of any gemstone — more visible brilliance than diamond. If your customers want serious sparkle without the diamond price tag, moissanite is the honest answer.
We operate from Surat — the city that cuts and polishes over 90% of the world's diamonds. Proximity means access, and access means better stones at fairer prices with full traceability.
From your first message to your customer’s unboxing — here’s what working with us looks like.
Pick from our ready collection or brief us on a custom design. A reference image and a description is all we need. No technical knowledge required.
We source matching stones with certificates and present options for your approval. For custom pieces, we produce CAD renders and a physical sample before any metal is cast.
List your pieces. Take orders. Collect payment. You don't need to commit to production until a customer has paid you. No inventory risk. No upfront spend.
Once you have an order, place it with us. We manufacture to your approved specification — cast, set, polished, and QC'd to a designer finish. Every time.
We ship in your branded packaging, with your certificate, tracked and insured, directly to your customer. Order to door in 7 days. Grandior nowhere to be seen.
You have the brand identity, the audience, and the creative vision. You don't need a factory — you need a production partner that performs like one. Grandior makes your brand operate like a business ten times its size, without the overhead.
Add a fine jewelry category, offer custom commissions, or dropship on demand — without holding a single piece until it sells. Expand your offering without expanding your risk.
For brands that run entirely online. List our ready collections under your name, or build a custom exclusive catalog — and let us fulfil every order directly to your customer, anywhere in the world.
You order when you have a sale. Until then, nothing is committed and nothing is at risk.
Production-level precision with a finish your customers will notice. Every piece checked against your approved sample before it leaves us.
From order confirmation to your customer's door in 7 days. Tracked, insured, and branded throughout. Fast enough to compete with anyone.
Custom pieces are exclusive to your brand — permanently. We never offer your designs to other partners. What you commission belongs to you, in your market and everywhere else.
We operate from Surat and Mumbai — the world's diamond capital. Every stone is certified. Every price is visible. No hidden margins, no bait-and-switch, no fine print.
Your packaging. Your certificate. Your inserts. Your brand on every touchpoint. Your customer never encounters Grandior. That is not a feature — it is the entire point.
Sourcing, design, manufacturing, fulfilment — one relationship, one point of contact, one team accountable for all of it. No chasing multiple vendors. No gaps in accountability.
Run your jewelry brand from a laptop. No studio, no workshop, no team required. If you can sell, we can supply. Your backend just works. Quietly. Without you having to think about it.
"We built Grandior because we were sellers ourselves. We know exactly what breaks when the backend isn't working — and we built the operation to make sure it never breaks for you."
What partners tell us
Ready to see if we're the right fit?
Book a 30-Minute CallWe didn't start Grandior as manufacturers. We started as sellers — running jewelry brands, managing customer expectations, chasing suppliers, and dealing with inconsistent quality, opaque pricing, and a supply chain that was built to disadvantage small buyers.
The backend of the jewelry business was broken. Too many middlemen. Too much room for margins to disappear quietly. Too easy for small brands to be overcharged, underserved, or simply misled about what they were buying. Fraud was common — and largely invisible to buyers who didn't know the industry.
We knew it could work differently. So we built the operation we always wished existed: transparent sourcing, fair pricing, designer-finish manufacturing, and a backend that actually works the way it should.
Fine jewelry should not require a production team, a warehouse, or a decade of industry contacts to sell. With the right partner behind you, it doesn't.
Our sourcing and production teams are based in Surat — the city that cuts and polishes over 90% of the world's diamonds — and Mumbai, India's commercial capital. Our client operations team is based in California, serving our US, European, and Australian brand partners in their timezone and business culture.
Twenty-five years of combined industry experience sits behind every order. We know where the stones come from, how they are graded, what they are actually worth, and how to manufacture to a standard that holds up under your customers' scrutiny.
Tell us what you're building — a first catalog, a custom piece, or a full production partnership. We respond to every enquiry within one business day with a straight answer on feasibility, timeline, and pricing. No sales pitch. No obligation.
