Technical specifications
Precision zirconia, measured to tolerance
Every LIRUI component is produced from high-density zirconia ceramic and checked against standard tolerance ratings and Vickers hardness metrics. Our formulations are chosen for dimensional stability, a consistent surface finish, and reliable hole geometry across bead, pendant, and component runs.
Request the full specification guide for tolerance tables, material purity standards, and hardness data for each formulation.

Dimensional guidelines
Beads, pendants, and structural accessories

Beads
Bead diameters and drilling
Standard bead diameters are supplied with matching hole sizes so each piece threads and seats consistently. Custom diameters and hole drilling can be specified for bespoke designs.
Pendants
Pendant contours and dimensions
Pendant contours are documented across length, width, and thickness, with drilling positions confirmed against your design. Full dimension schematics are available on request.


Structural accessories
Components and custom accessories
Jewelry components and customized ceramic accessories are dimensioned to your drawings. Hole sizes, surface finish, and tolerances are agreed before production begins.
