Professional-grade Immersion & Specific Gravity Liquid (RI 1.765 / SG 3.32). Formulated from premium Methylene Iodide, this dual-purpose fluid provides instant specific gravity separation (3.32 SG) to tell loose moissanite apart from real diamonds. It eliminates surface reflections, enabling analysis of internal inclusions, origin, and treatment in rubies and sapphires. Specially formulated for unmounted loose stones, it is a critical asset for appraisal labs, jewelers, and gem buyers.

Premium Gemological Immersion & Specific Gravity Testing Liquid (RI 1.765 / SG 3.32)
Ensure absolute accuracy in your jewelry appraisal, buying, and laboratory sorting workflows with this professional Immersion / SG Liquid. Manufactured from high-purity Methylene Iodide (Diiodomethane), this premium chemical formulation is an essential diagnostic fluid for gemologists, loose stone dealers, and jewelry manufacturers.
By utilizing fixed physical principles—Specific Gravity (SG) and Refractive Index (RI)—this heavy fluid bypasses the limitations of basic electronic testers to deliver definitive, foolproof results for loose gemstones.

🔬 Advanced Refractive Index Matching & Treatment Detection
Engineered with a precise optical Refractive Index of 1.765, this immersion fluid perfectly matches the optical characteristics of natural corundum. When unmounted rubies or sapphires are submerged:
  • Eliminates Surface Glare: Outer facet reflections disappear completely, giving an unobstructed view inside the stone.
  • Exposes Hidden Treatments: Easily spot lattice diffusion layers, glass/resin fracture fillings, and composite assembly lines in gemstone doublets or triplets.
  • Origin Diagnostics: Allows rapid analysis of internal "fingerprint" inclusions and natural color-zoning to help verify gemstone origin.
💎 Instant Moissanite vs. Genuine Diamond Separation
Operating at a calibrated natural density of 3.32 SG, this heavy liquid offers an un-fakeable physical sorting method for loose parcels. Because electronic testers can be tricked by thermal conductivity, this density test provides physical certainty:


  • Loose Moissanite (3.22 SG) Floats cleanly on the surface of the fluid.
  • Genuine Diamond (3.52 SG) Sinks rapidly directly to the bottom.
📦 Versatile Multi-Tool For Laboratories
  • Heavy Liquid Parcel Sorting: Efficiently separates lower-density gems like emerald, tourmaline, jadeite, and quartz (which float) from high-density gems like ruby, sapphire, topaz, zircon, and garnet (which sink).
  • Refractometer Contact Bridge: Can be utilized as a contact fluid on standard gem refractometers to obtain accurate RI readings for any gem under 1.74 RI.
    ⚠️ GHS HAZARD & HANDLING SAFETY WARNING
    • Chemical Composition: Diiodomethane (CAS No. 75-11-6).
