Gold color and setting
Rings are made in yellow, white or rose gold. Rhodium plating is applied on white gold, and black plating on models where contrast is wanted. Stone seats are calculated according to the stone size at the CAD stage; prong, channel, pavé or bezel setting is chosen according to the model. The fit of every stone is checked one by one after setting.
Stone sourcing
We can source lab-grown diamonds in the size, color and clarity range you specify, or work with stones you send us. The product information clearly states that the stone used is a lab-grown diamond.
Frequently asked questions
Can I have the same ring made with both a lab-grown and a natural diamond?
Yes. The model stays the same, only the stone changes. This way you can offer the same design at two different levels.
Do you produce my own design?
Yes. We do contract manufacturing from your drawing, photo or CAD file; we also offer custom design for a new model.
What is needed for a quote?
The model image, stone size and quality, gold karat and color, and the estimated quantity are enough. You can send them via the quote form or WhatsApp.
