A 1.33-carat rectangular octagonal lab-created strontium titanate diamond simulant center with 0.43 carats of white zircon accents in 18K yellow gold over sterling silver creates a ring where the highest-dispersion white stone is framed by the sparkle of natural zircon - two optical performers working together. The rectangular octagonal cut gives the strontium titanate center architectural precision while its exceptional fire creates the rainbow-color light events that exceed diamond's dispersion. The zircon accents add natural gemstone sparkle with their own distinctive high refractive index. In warm gold, both stones appear richer. An optically outstanding ring.
