Source jewelry factory · Lab-grown diamonds, moissanite & fine jewelry · MOQ from 1 piece
Our capabilities · Source factory since 2015
A true jewelry factory — rough stone to finished piece.
SGARIT isn’t a trading company. We run our own lab-grown diamond production, gemstone cutting, CAD, casting, stone-setting, finishing and quality control — all under one roof at our factory in Guangzhou, China.
Our factory
One factory, end to end
The full loop, under one roof.
Most suppliers handle one or two steps and outsource the rest. As a source jewelry factory, we own every stage — which is how we keep quality tight, turnarounds short, and lab-grown stones 60–90% below natural.
1
Lab-grown stone production
We grow our own HPHT and CVD diamonds, so rough supply starts in-house.
2
Gemstone cutting
Diamonds, moissanite and colored stones cut and calibrated at the source.
3
CAD & 3D design
A free 3D render plus a 360° video in 48 hours — approved before we cut metal.
4
Lost-wax casting
925 silver, brass, 9K–24K gold and platinum cast on-site.
5
Stone setting
Hand and micro setting — pavé, prong, channel and bezel.
6
Finishing & plating
Polishing, rhodium and gold plating, PVD and gold vermeil.
7
Engraving & branding
Logos, hallmarks and your own packaging — full OEM.
8
4-step quality control
Inspected at every stage, with a 99.5% pass rate.
9
Worldwide shipping
Insured delivery to 100+ countries, plus dropshipping and FBA prep.
Why this matters
What makes us a real source factory.
Plenty of websites say “factory.” Here’s what actually sits behind ours.
We make our own stones
Few jewelry factories run their own HPHT/CVD lab-grown diamond production. We do — which means better supply, pricing and traceability, with every lab-grown stone clearly identified as lab-grown.
We cut at the source
In-house gemstone and moissanite cutting means tighter calibration and faster turnarounds than buying loose stones from a third party.
One roof, design to doorstep
From rough stone to a finished, branded, shipped piece — without handing your project across a chain of middlemen who each add cost and time.
Start at one piece, scale to bulk
Test a design at 1-piece MOQ, move to your own private molds, then full production — all on your own timeline.
