Observe refractive-index readings for suitable gemstones with a gem refractometer and light.

Observe gemstone refractive-index readings

• ✅ Add an optical reading to your examination – The tool provides a 1.30–1.81 RI range.
• ✅ View the scale through an eyepiece – The optical assembly lets you observe the sample reading.
• ✅ Illuminate the measurement setup – The included light supplies illumination.

• Specifications: refractive-index range 1.30–1.81 RI; 0.01 RI scale divisions; approximately 61 × 130 × 32 mm.

• Package: refractometer, light and instructions.

Use appropriate contact fluid and testing procedures. A refractive-index reading alone does not establish authenticity or value.
