How Our Gemology Team Tests Moissanite Quality Before It Ships - Moissanite Shine

At Moissanite Shine, every stone you receive has passed through a structured, multi-point quality review conducted by our in-house gemology team. We don't rely on supplier certificates alone — we inspect every shipment ourselves, because your confidence in what you're buying depends on ours. This article walks you through exactly what we test, how we test it, and why each checkpoint matters for the stone you'll wear every day. Shop GRA certified DEF VVS1 moissanite rings online USA →

Why We Inspect Every Stone Ourselves

Moissanite is produced in controlled lab environments — but "lab-created" does not mean "automatically perfect." Cut geometry, polish consistency, and optical symmetry can vary significantly between stones, even within the same batch from the same supplier. Our gemology team reviews each incoming shipment against our internal grading standards before any stone is photographed, listed, or fulfilled. Stones that don't meet our thresholds are returned — no exceptions.

The 6-Point Quality Inspection

# Inspection Point What We Check Our Standard Why It Matters
1 Cut Grade Verification Table percentage, depth percentage, crown angle, pavilion angle Excellent cut only — Very Good or below rejected Cut is the most important factor in optical performance — an excellent cut maximizes every property that makes moissanite visually superior. Cut quality guide →
2 Optical Performance Testing Brilliance (white light return), fire (spectral color dispersion), scintillation (sparkle pattern under movement) Hands-on visual assessment under controlled lighting — not spec-sheet review alone A stone can pass proportions on paper but perform poorly visually; direct optical assessment is the definitive test. Why moissanite has more fire than diamond →
3 Color Grade Confirmation Color grade (D–F colorless range) assessed under neutral daylight-equivalent lighting; face-up warm tint check DEF (colorless) confirmed independently — any warm tint disqualifies the stone Supplier documentation can misrepresent color — independent assessment is the only reliable confirmation. Color grades explained →
4 Clarity Inspection (Loupe & Microscope) 10× loupe magnification; microscope for larger stones; inclusions, surface blemishes, polish marks documented VS1 clarity minimum — stones below VS1 not accepted VVS1 is our standard for all listed stones; step-cut stones (emerald, asscher) particularly require high clarity as their open facets make inclusions more visible
5 Symmetry & Polish Assessment Facet alignment, culet centering, girdle evenness Asymmetric stones rejected regardless of other grades Poor symmetry creates uneven light return — not visible in product photos but immediately noticeable in person; no grade exception for symmetry failures
6 GRA Certificate Cross-Verification GRA certificate data compared against team's independent assessment of the actual stone Certificate must match our findings — discrepancies result in rejection and return Certificate fraud is rare but documented in the moissanite market; our independent assessment is the final quality checkpoint.

What Happens to Stones That Don't Pass?

What Happens Details
Returned to supplier Rejected stones are returned with documented findings — specific inspection point failures recorded
Supplier batch tracking Rejection rates by supplier batch are recorded over time — this data directly informs sourcing decisions and supplier relationships
No seconds or discounted sales Rejected stones are not sold as "seconds" or at discount — they leave our inventory entirely
