A curated catalog of SOSNA Diamonds house designs in natural white diamonds. GIA-certified stones, executed in platinum 950 or 18k white gold. Each piece made to order in Prague — 4–8 weeks.
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.
