Catalog vs. Bespoke

What “made to order” means

The design is in the catalog. The stone is not — you choose it with us from 2–4 GIA-certified candidates we propose to fit your budget, carat weight and color/clarity range. The piece is then built in our Prague atelier in 4–8 weeks.

For an original design from scratch (drawing, CAD, prototype), see bespoke (1:1 commission). For a loose stone without a setting, see private sourcing.
