Before you begin

A few useful details.

Ask a different question
Do I need a complete design?

No. A reference image, occasion, stone shape or general mood is enough for us to begin narrowing the direction.

Can I review the design first?

Yes. The stone details and CAD direction are shared for approval before production begins.

Is a diamond report included?

Report availability depends on the selected stone and is made clear when the options are presented.

Can you ship internationally?

Worldwide enquiries are welcome. The available shipping route, timing and cost are confirmed for each destination before dispatch.
