4.80 carats of asscher-cut lab-created strontium titanate diamond simulant set in 18K yellow gold over sterling silver hoop earrings creates a piece where an extraordinary optical stone and an architectural cut combine in a warm gold hoop format. The asscher cut's hall-of-mirrors step faceting shows strontium titanate's exceptional dispersion in the specific mode of step cuts - where the rainbow-color fire appears in sweeping, dramatic events rather than the pinpoint sparkle of brilliant cuts. At 4.80 carats across the hoops, the strontium titanate has the surface area to deliver its fire spectacularly. In warm gold, every color event appears richer.
