Our subsidiary services

Rutile

In addition to its traditional services, Djeva also proposes rutile crystals.

Appraisals

As a service to its clientele, Djeva checks in polarised light the position of the optical axes on semi-finished pieces.

Thermal treatments

On customers’ request, Djeva carries out, before final polishing, a thermal treatment to eliminate the internal stresses provoked by the machine-finishing.
