Who We Are

A diamond manufacturer, not a middleman.

Variation is a certified fine-jewelry manufacturer specializing in lab-grown diamonds. We grow-source, cut, certify, set, and finish — supplying loose IGI-certified stones and fully finished diamond jewelry to brands, designers, and retailers around the world.

Everything happens under one roof: diamond sourcing, CAD, casting, stone-setting, finishing, and quality control. That means one accountable partner for OEM, ODM, and private-label production — with full control over quality, timelines, and your intellectual property.

"Every stone IGI certified, every piece made in-house — from a single loose diamond to a full collection."

Whether you arrive with finished tech packs or a first sketch, we take it from concept to certified, export-ready collection.

Why It Matters

Built different.

Every Diamond IGI Certified

Each stone is independently graded for cut, colour, clarity, and carat — verified quality your customers can trust, on paper.

Everything In-House

Diamonds, CAD, casting, setting, finishing, and QC under one roof — no outsourcing, no middlemen marking up your order.

CVD & HPHT, Any Shape

Round, oval, emerald, cushion, pear and more — including the rare Portuguese cut — in the grades and sizes your line needs.

Your IP, Protected

Every project is covered by a strict NDA. Your designs, molds, and collections stay entirely yours.

How It Works

From sketch to certificate.

A clear, four-step path with a sample in your hands before you commit to a run.

Step One
Design & CAD

Share your designs, sketches, or references, along with the diamond shapes and grades you want. We refine everything into production-ready 3D CADs and quote — all under NDA.

Step Two
Sampling

We set a certified diamond into a physical sample for your approval, usually within two weeks, so you sign off before any bulk run.

Step Three
Production

On approval, your order goes into production — completed in three to four weeks, with certification and quality control at every stage.

Step Four
Dispatch

Finished pieces pass final inspection and ship with their IGI certificates, export-ready, from our facility in India.

Who We Work With

Made for brands at every stage.

From a first-time founder launching a debut collection to an established label running monthly ranges, our low minimums and 10,000-piece monthly capacity scale with you — startups, boutiques, designers, and retailers worldwide.

Diamond manufacturing, answered.

The questions we hear most from brands and designers. If yours isn't here, message us and we'll answer directly.

Message Us on WhatsApp
What is your minimum order quantity (MOQ)?
Our MOQ is 5 pieces per style — low enough to launch or test a collection, while still delivering full manufacturing and certification quality. Running several styles? We can plan them into one production cycle.
Are your diamonds certified?
Yes. Every lab-grown diamond we set is IGI certified — independently graded for cut, colour, clarity and carat, with a certificate that ships with each piece.
Do you use CVD or HPHT diamonds?
Both. We source and set both CVD and HPHT lab-grown diamonds, in the shapes, sizes, and grades your collection calls for.
What shapes and grades can you supply?
All popular shapes — round, oval, emerald, cushion, pear and more, including the rare Portuguese cut — across a full range of colour and clarity grades. Tell us your target and we'll match it.
Which metals do you set them in?
9K to 18K gold, BIS hallmarked, in yellow, white and rose, plus 950 platinum. All nickel-free and lead-free for compliant sale in the US and EU.
Do you supply loose diamonds or finished jewelry?
Both. We can supply certified loose lab-grown diamonds, fully finished diamond jewelry, or a mix of the two.
Do you offer OEM, ODM, and private label?
Yes — all three, entirely in-house. OEM from your finished designs, ODM from your concept, and private label fully branded and packaged as your own.
How long from design to delivery?
About two weeks for a sample, then three to four weeks for production once approved — so most first orders are ready within roughly five to six weeks.
Will my designs stay confidential?
Always. Every project is covered by a strict NDA, and your designs and molds remain entirely your intellectual property.
