-2 Rounddouble cutwhite
Small round diamonds for pavé, halos, eternity bands, side stones and watch settings, from +00‑0 up to -6 sieve, with -2 as our specialty. Polished on automatic machines from natural rough first, and from lab-grown CVD and HPHT rough on the same lines.
Natural rough is our main work. Each parcel is planned on Sarine systems for yield and polished to round double cut.
Lab-grown CVD and HPHT rough runs through the same planning, laser and polishing stations as natural goods, kept in separate lots.
