How we work
Every client has a different need, so we offer four ways of working.
- Contract manufacturing: we produce your finished design or technical file under your brand.
- Custom design: we develop the model with you from an idea, sketch or reference image.
- Private label: you offer selected models from OSKA collections under your own brand.
- Wholesale orders: made-to-order production runs for jewelers and retail chains.
Atelier services
- CAD design and prototyping
- Stone setting, plating (rhodium, black rhodium, gold) and finishing
- Casting, assembly, polishing and quality control
- Samples before a production run
How the process works
- Request: you send us the model, karat, estimated quantity and target market.
- Quotation: we prepare a project-specific quotation based on weight, stones and workmanship.
- Model and sample: the CAD drawing is sent for your approval and a sample is made when needed.
- Production: casting, assembly, stone setting and polishing are completed in our atelier.
- Inspection and delivery: each piece is checked for dimensions, stones and surface before delivery.
Why Istanbul
Istanbul is a long-established jewelry manufacturing centre where skilled craftsmanship, stone supply and workshop infrastructure sit in the same district. That proximity shortens the path from drawing to finished piece and makes close quality control possible on labour-intensive designs. The city is also close to both European and Gulf markets.
Frequently asked questions
Who do you work with?
Jewelry brands, jewelers, retail chains, wholesalers and designers preparing their own collections. For individual custom orders, you can also message us on WhatsApp.
Why are there no prices on the site?
The gold price changes daily, and cost also depends on karat, weight, stones and workmanship. We therefore quote each project separately.
Where do I start?
Start with whatever you have: a drawing, a photo, a sample or a model you like from our collections. Fill in the quotation form or message us on WhatsApp.
