Old European cut lab-created strontium titanate diamond simulant with lab-created white sapphire accents in 18K yellow gold over sterling silver leverback earrings combine a specific historical cut aesthetic with exceptional optical performance. The old European cut - a precursor to the modern round brilliant with a higher crown, smaller table, and circular culet - creates a distinctly different light return from modern cuts: softer, more diffuse, more reminiscent of candlelight-era fine jewelry. Applied to strontium titanate - the highest-dispersion white stone available, with more fire than diamond - the old European faceting delivers that exceptional dispersion in a romantic, vintage optical mode. The white sapphire accents add precise bright sparkle as a frame. At 0.95 inches long with warm gold leverbacks, these earrings have both presence and security.
