Kattri has an intriguing website, but alas, it gives no detail at all on the pieces shown or how/where to buy them. This ring, part of the asymmetry collection, is summed up as, “Asymmetry, KATTRI’s third collection, was inspired by the shapes and lines used throughout art deco architecture. KATTRI has juxtaposed certain characteristics of art deco with a strong element of asymmetry to create a more unconventional and unique design. This features a new addition to KATTRI’s pieces; the iridescent and timeless pearl.”
