Engineered for perfection

We refused every compromise. This is the loupe.

Grading starts with detailed inspection of the diamond, so we built the optic our own graders demand. A corrected triplet that shows the stone exactly as it is: no color fringing, no edge distortion, no excuses.

Optics

Corrected to the very edge

The aplanatic, achromatic triplet combines three precision-ground elements so the image stays sharp and true across the whole 21 mm field, the correction serious grading demands.

  • Achromatic: color-corrected, no fringing on facet edges
  • Aplanatic: distortion-free, flat field edge to edge
  • 10× magnification, the reference for clarity grading
Coating & finish

Built to disappear into daily use

A matte anodized finish on the machined aluminum body keeps reflections away from the stone, resists scratches and fingerprints, and stays comfortable in the hand through a full day at the bench.

  • Matte black anodized aluminum body
  • Non-reflective, no stray glare on the stone
  • Resists scratches through years of bench use
Ergonomics

Opens with one hand, sits right in it

The fold-out cover swings smoothly on a machined pivot and doubles as a grip. Balanced weight and a rounded profile keep the loupe steady against your eye, and protect the lens the moment you fold it away.

  • Smooth one-handed fold-out action
  • Cover doubles as a grip and lens guard
  • Lanyard attachment for showroom days
