Case Study: GRA-Certified Moissanite Stud Earrings in 925 Sterling Silver

This is a production case study for Moissanite Stud Earrings – 2ct GRA Certified 925 Silver – a piece MIRAMETAL builds in its own Guangzhou workshop. It documents how the piece is actually made, what a buyer controls before production starts, and how the order moves from a reference to a packed carton.

What this piece has to do

Moissanite looks like diamond but behaves differently in setting. A brand selling moissanite to customers who compare it against mined diamond has to answer two questions before a customer buys: is the stone certified, and will it stay secure in a silver mount?

How MIRAMETAL produces it

Every step below runs in-house – CAD design, mold-making, casting, stone setting, polishing, plating and quality control. Nothing is subcontracted, which is what keeps an approved sample and a bulk run on the same route.

Stone intake

Moissanite arrives with GRA certification documents that travel with the shipment, so the certificate can be traced to the stones in your order.

Setting

The 2ct total is set as a matched pair in 925 sterling silver, and both stones are checked under magnification for seat depth and claw tension before the pair is released.

Polishing and finish

The sterling silver is polished to a bright finish so the moissanite reads as the focal point rather than the mount.

Inspection

100% inspection before packing – stone security, surface finish, pair matching and hallmark legibility.

Quality and compliance

ISO 9001 certified workshop, EU REACH and US CPSIA compliant. Every piece is inspected before it is packed: stone security where stones are involved, plating coverage, surface finish and the 925 hallmark. Inspection photos can be provided before dispatch, and the QC record for a batch is kept so a repeat order can be checked against the original approval.

Order terms

MIRAMETAL has been making jewelry in Guangzhou Since 1990 – 30+ years of production – and works with jewelry brands in international markets. Orders start from 1 piece, sampling runs 3-7 days after design approval, and production covers CAD design, mold-making, casting, stone setting, polishing, plating and quality control.

Frequently asked questions

Is the moissanite in these earrings certified?

Yes. These studs are set with GRA-certified moissanite, and the certification paperwork travels with the shipment so you can file it for your own customers.

What is the minimum order for moissanite jewelry?

One piece. MIRAMETAL produces jewelry from a single unit, so a moissanite line can be launched as a sample order before any bulk commitment.

How long does sampling take?

3-7 days after design approval. Sampling runs on the same in-house line as production, so an approved sample is the piece your bulk order reproduces.

Will the stones loosen during shipping?

They are inspected for seat depth and claw tension before the earrings are packed, and the pair is checked as a set so both stones sit at the same height.
