Quality control runs at two levels: the stones and the piece. Centre stones ship with IGI or GIA certification under your programme, verifiable by report number against the laboratory’s own database. Finished pieces pass station QC through production and a final inspection against your approved pre-production sample.

Before shipment, orders are photographed and filmed under standard lighting. You review what actually ships, not a sample photo taken six months ago — which means remote approval is a real decision, and a dispute after delivery is rare because the evidence already exists.

In detail

How quality control & testing actually works here

Quality control inspection of finished jewelry at Vesta Jewelry

What gets checked

Setting security under pressure, stone alignment, finish consistency, plating coverage and thickness, metal purity marks, dimensional accuracy against the specification, and clasp and hinge function on chains and bracelets.

Inspection against the PPS

Bulk is measured against your signed-off pre-production sample rather than against a drawing. A drawing is open to interpretation; a physical approved object is not. This is why we insist on a PPS even when a client is in a hurry.

Stone verification

Report numbers are listed on packing documentation so your receiving team can verify each certified stone directly with the issuing laboratory before goods enter stock. We would rather you checked than trusted.

Documentation you keep

QC photographs and video per order, retained on both sides. If something is wrong on arrival, the comparison is immediate and factual rather than a negotiation about what left the floor.

The five inspection stages

Quality control is not a final gate, it runs through the build: material inspection before anything is cut, casting inspection for porosity and fill, stone setting inspection for security and alignment, polishing inspection for finish and plating coverage, and final product inspection against your approved sample. Catching a casting fault at station two costs an hour; catching it at dispatch costs a production run.

Metal and material standards

Metals to declared purity — 9K, 10K, 14K (Au585), 18K (Au750) gold, platinum (Pt950) and 925 sterling silver — with hallmarking to your market’s requirements. Materials are nickel-free and lead-free as standard, which matters for EU and US retail compliance and for the customer who reacts to everything.

Warranty and after-sales

Quality problems caused by manufacturing are ours to fix — repair or replacement, and we would rather you told us than absorbed it. Report a quality issue with photographs within the inspection window agreed in your order confirmation and it is handled; wear damage and after-use damage sit outside that, as they do with any manufacturer honest about it.

If a piece is faulty

Photograph it and tell us. Manufacturing faults are ours to repair or replace — that is what sampling, a PPS and documented QC exist to prevent in the first place, and when the system fails the cost of failure is not yours to carry.
