Why we love it

The Seraph ring was crafted to enhance the fiery brilliance of authentic antique-cut stones, meticulously fashioned by hand in the soft glow of candlelight. Inspired by its meaning of 'burning ones, fiery ones', we selected this stone as the centerpiece for our inaugural Seraph ring. With its elevated crown and petite table peeking just above the lower bezel, this stone accentuates the distinctive characteristics of the cushion-like old mine cut.
