Prism Shifter 1.20 is a By Erstwhile original design centering a 1.20 carat antique old European cut diamond set in an ultra-low profile 18k yellow gold mounting, with crisp geometric detailing inspired by Art Deco–era jewelry, reinterpreted through a modern lens. Step-cut baguette diamonds flank the center, adding quiet structure and contrast, while delicate pavé accents beneath the crown reward closer inspection. Clean lines, refined proportions, and a comfortably grounded profile make this ring both architectural and wearable.
By Erstwhile designs focus on proportion, restraint, and longevity—reinterpreting historic details through a modern lens. Handcrafted in the heart of New York City, the Erstwhile Collection showcases rare antique diamonds elegantly set in precious metals.
