  • Loose Rough

    Natural gemstones in raw or minimally polished form, ranging from transparent to opaque.

  • Loose Cut in any style

    Gemstones shaped into various forms such as faceted, cabochon, or beads, with or without drilling.

  • Set in jewellery

    Gemstones mounted in jewellery or decorative items using open or closed back settings.

  • Carvings

    Gemstones hand-carved into artistic, cultural, or decorative designs with fine craftsmanship.

  • Beads strung on a wire

    Gemstones fashioned into beads and assembled into necklaces, bracelets, or decorative strands.

All materials submitted to JGL undergo an extensive regimented series of testing through:
  • Independent Expert Evaluation

    Assessment by two or more certified gemologists/graders.

  • Industry-Standard Instrument Testing

    Testing using globally accepted gemological instruments.

  • Advanced Scientific Spectral Analysis
