In an industry flooded with lab-created glass, resin-injected composites, and gamma-irradiated counterfeits, SUIYING maintains a strict scientific testing protocol. We operate an uncompromising gemological verification framework before any rough mineral enters our lapidary studio.
Our 4-Tier Scientific Testing Standard
1. Specific Gravity & Hydrostatic Balance
Every batch of raw crystal rough undergoes hydrostatic specific gravity testing to measure true atomic density, immediately distinguishing natural quartz (SG 2.65) and natural beryl from lightweight polymer imitations or dense leaded glass.
2. Refractive Index (RI) & Polariscopic Examination
Using precision optical refractometers and cross-polarized light filters, our gemologists observe internal light propagation to verify genuine anisotropic crystalline structure versus isotropic synthetic polymers.
3. Raman Spectroscopy & Infrared Spectrometry (FTIR)
To detect microscopic resin injections, paraffin vacuum stabilization, or artificial organic dyes, random specimens from every geological lot undergo infrared spectroscopy to guarantee zero polymer peaks in the molecular fingerprint.
4. Zero Thermal Baking Verification
Naturally occurring Citrine owes its golden luster to subterranean geothermal iron oxidation over millions of years. We reject industrially heat-baked Brazilian Amethyst (often sold deceptively as citrine), ensuring your talisman radiates authentic solar resonance.
Individual Specimen Certificate
Every finished SUIYING talisman is assigned an individualized atelier registration code, guaranteeing that the piece you wear on your wrist is 100% natural, untreated, and geologically sovereign.
