OEM and ODM 18K gold gemstone jewelry manufacturing
Gemformia supports both customer-led designs and design development for finished gemstone jewelry. Our team in Daluotang, Panyu, Guangzhou works with jewelry brands, stores, online sellers, designers and individual custom projects.
OEM: manufacture an agreed customer design
Start with your CAD drawing, STL file or an established design reference. Specify the gemstone, 18K gold requirements, jewelry dimensions, setting and finish. We review the construction and agree the production specifications before manufacturing.
ODM: develop a design with our team
Start with a sketch, reference photograph or design brief and budget. We work through the design proposal, hand drawing or 3D modeling, stone requirements and manufacturing stages with you. This is design development for a finished jewelry project.
Finished custom jewelry starts from one piece. We’ll work to complete your custom piece as soon as possible and confirm the timeline with you before production. Timing depends on the design, materials and manufacturing requirements. Complex designs may take longer; shipping time is additional.
Custom 18K gold jewelry from one piece
Gemformia makes custom colored gemstone jewelry and connects design development with gemstone processing and setting. Our current gallery includes colored gemstone ring designs and textured bracelets, with an 18K gold royal blue ring among the examples. Metal and gemstone specifications are confirmed for each custom project.
These pieces show possible starting points for a custom project. They are not fixed-price retail listings. We review the design, stone specifications, metal requirements, finished size and quantity before confirming what the work involves.
Custom gemstone rings in 18K gold
Develop a ring around your chosen gemstone, setting and ring size. Our current ring gallery includes pink sapphire, aquamarine, royal blue gemstone and yellow jadeite designs. Share a CAD file, sketch or reference photo, together with the stone dimensions and the details you would like to change.
For a custom emerald ring, tell us whether you require a natural or lab-grown stone. Include the stone dimensions and your design reference so we can review the requirements. You can explore our lab-grown emerald rings before discussing your own design.
Custom earrings in 18K gold
Work with Gemformia as your custom earring manufacturer, from design development through gemstone processing and setting. We can review lab-grown emerald earrings and other colored gemstone earring designs in 18K gold against your reference and specifications.
For your own pair, share the gemstone dimensions, desired length, setting reference and fastening details. We review these together with your preferred metal and finish before quoting. Finished custom jewelry starts from one piece; pricing and specifications are agreed for each project.
Can you make jewelry from my photo, sketch or CAD file?
If you already have an STL file or CAD drawing, include it in your brief. A reference photograph or hand-drawn sketch is also useful when the design is still being developed. Describe the parts you want to retain or change, rather than relying on the image alone.
For rings, include the size and the dimensions of any main stone. For earrings, explain the desired dimensions, wearing proportions and fastening details. Tell us your preferred metal and finish. If you have a target budget, sharing it helps us review the customization approach.
