The "Cloudy Stone" Trap: Why Simulants & Plated Brass Don’t Last
Many social-media jewelry brands charge $400–$800 for "lab-created white sapphire" or cubic zirconia set in gold-plated sterling silver or brass. Within months of handwashing, lotion, and daily wear, porous simulants scratch and absorb skin oils (turning milky gray), while thin gold plating rubs off. Real lab-grown diamonds score a perfect 10 on the Mohs hardness scale—meaning they will never cloud, scratch, or lose their crisp white flash for generations.
Lab-Grown Diamond vs. Moissanite in Small Melee Sizes (2mm–3mm)
Because moissanite is doubly refractive with a 2.65 refractive index, small stones in a tennis bracelet can throw an unnatural "disco-ball" rainbow glare under restaurant or office lighting. Lab-grown diamonds are singly refractive (2.42 RI)—producing the unmistakable crisp white brilliance and high-contrast scintillation of pure diamond.

Frequently Asked Questions
Will a Viviour lab-grown diamond pass a diamond tester?
Yes. Because Viviour uses 100% real lab-grown diamonds (pure crystallized carbon), they test identically to earth-mined diamonds on thermal and electrical conductivity testers.
