Diamond and Lab-Grown Diamond Jewelry Manufacturing
OSKA manufactures jewelry set with natural diamonds and lab-grown diamonds in Istanbul for brands and jewelers. From solitaire rings to full eternity tennis bracelets, setting design, stone setting and final inspection are done in the same atelier.
Natural or lab-grown diamonds?
A lab-grown diamond has the same chemical and optical structure as a natural diamond; the difference is that it is grown in a controlled environment rather than underground. Brands that want to offer a larger stone for the same budget choose lab-grown; those keeping a traditional fine-jewelry line choose natural diamonds. The manufacturing process is identical for both, and the stone type is stated clearly in the product information. For details, see lab-grown diamond jewelry manufacturing.

Settings and stone setting
The setting determines the quality of a stone-set piece as much as the stone does. Stone seats are calculated at the CAD stage from the diameter of each stone; prong, channel, pavé or bezel setting is chosen according to the design. After setting, the seat and security of every stone are checked. Settings are made in 9K, 10K, 14K or 18K gold.
Stone supply
We can source stones to the size, colour and clarity range you specify, or work with stones you send. If you need certified stones, simply state this at the quotation stage.
Frequently asked questions
Can I send my own stones?
Yes. We design the setting to the dimensions of your stones and carry out the setting.
Can the same design be made with both natural and lab-grown diamonds?
Yes. The model stays the same and only the stone changes, so you can offer one design at two price levels.
What do you need for a quotation?
