1. Multi-Layer 18K Thick Gold Vermeil vs Flash Water Plating

Master jewelry pieces undergo multi-layer vacuum PVD electroplating with genuine 18K yellow, white, or rose gold at a thickness of 3 to 5 microns over a 925 sterling silver or solid brass core, tested for sweat resistance.

Flash water plating uses mere 0.05-micron gold washes that oxidize and rub off to expose gray metal within weeks.

2. Diamond Tester Conductivity: D-Color VVS1 Moissanite

Our fine jewelry pieces utilize hand-set D-Color VVS1 lab-created moissanite gemstones featuring 2.65 refractive index (higher than natural diamond at 2.42), 100% passing portable thermal diamond tester pens with audible confirmation.
